+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:

+OpenAPI Petstore
+- API version: 1.0.0
+
+This is a sample server Petstore server. For this sample, you can use the api key `special-key` to test the authorization filters.
+
+
+*Automatically generated by the [OpenAPI Generator](https://openapi-generator.tech)*
+
+
+## Requirements
+
+Building the API client library requires:
+1. Java 1.8+

+
+## Installation
+
+To install the API client library to your local Maven repository, simply execute:
+
+```shell
+mvn clean install
+```
+
+To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:
+
+```shell
+mvn clean deploy
+```
+
+Refer to the [OSSRH Guide](http://central.sonatype.org/pages/ossrh-guide.html) for more information.

+<dependency>
+  <groupId>org.openapitools</groupId>
+  <artifactId>petstore-okhttp-gson</artifactId>
+  <version>1.0.0</version>
+  <scope>compile</scope>
+</dependency>
+```
+
+### Gradle users
+
+Add this dependency to your project's build file:
+
+```groovy
+  repositories {
+    mavenCentral()     // Needed if the 'petstore-okhttp-gson' jar has been published to maven central.
+    mavenLocal()       // Needed if the 'petstore-okhttp-gson' jar has been published to the local maven repo.
+  }
+
+  dependencies {
+     implementation "org.openapitools:petstore-okhttp-gson:1.0.0"
+  }
+```
+
+### Others

+Please follow the [installation](#installation) instruction and execute the following Java code:
+
+```java
+
+// Import classes:
+import org.openapitools.client.ApiClient;
+import org.openapitools.client.ApiException;
+import org.openapitools.client.Configuration;
+import org.openapitools.client.auth.*;
+import org.openapitools.client.models.*;
+import org.openapitools.client.api.PetApi;
+
+public class Example {
+  public static void main(String[] args) {
+    ApiClient defaultClient = Configuration.getDefaultApiClient();
+    defaultClient.setBasePath("http://petstore.swagger.io/v2");
+    
+    // Configure OAuth2 access token for authorization: petstore_auth
+    OAuth petstore_auth = (OAuth) defaultClient.getAuthentication("petstore_auth");
+    petstore_auth.setAccessToken("YOUR ACCESS TOKEN");
+
+    PetApi apiInstance = new PetApi(defaultClient);
+    Pet pet = new Pet(); // Pet | Pet object that needs to be added to the store
+    try {
+      Pet result = apiInstance.addPet(pet);
+      System.out.println(result);
+    } catch (ApiException e) {
+      System.err.println("Exception when calling PetApi#addPet");
+      System.err.println("Status code: " + e.getCode());
+      System.err.println("Reason: " + e.getResponseBody());
+      System.err.println("Response headers: " + e.getResponseHeaders());
+      e.printStackTrace();
+    }
+  }
+}
+
+```

+- **Location**: HTTP header
+
+### petstore_auth
+
+- **Type**: OAuth

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
+#
+#       You can find Gradle at https://github.com/gradle/gradle/.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+
+OpenAPI Petstore
+
+- API version: 1.0.0
+
+This is a sample server Petstore server. For this sample, you can use the api key `special-key` to test the authorization filters.
+
+
+*Automatically generated by the [OpenAPI Generator](https://openapi-generator.tech)*
+
+## Requirements
+
+Building the API client library requires:
+
+1. Java 1.8+
+2. Maven (3.8.3+)/Gradle (7.2+)
+
+## Installation
+
+To install the API client library to your local Maven repository, simply execute:
+
+```shell
+mvn clean install
+```
+
+To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:
+
+```shell
+mvn clean deploy
+```
+
+Refer to the [OSSRH Guide](http://central.sonatype.org/pages/ossrh-guide.html) for more information.
+
+### Maven users
+
+Add this dependency to your project's POM:
+
+```xml
+<dependency>
+  <groupId>org.openapitools</groupId>
+  <artifactId>petstore-openapi3-jersey2-java8</artifactId>
+  <version>1.0.0</version>
+  <scope>compile</scope>
+</dependency>
+```
+
+### Gradle users
+
+Add this dependency to your project's build file:
+
+```groovy
+  repositories {
+    mavenCentral()     // Needed if the 'petstore-openapi3-jersey2-java8' jar has been published to maven central.
+    mavenLocal()       // Needed if the 'petstore-openapi3-jersey2-java8' jar has been published to the local maven repo.
+  }
+
+  dependencies {
+     implementation "org.openapitools:petstore-openapi3-jersey2-java8:1.0.0"
+  }
+```
+
+### Others
+
+At first generate the JAR by executing:
+
+```shell
+mvn clean package
+```
+
+Then manually install the following JARs:
+
+- `target/petstore-openapi3-jersey2-java8-1.0.0.jar`
+- `target/lib/*.jar`
+
+## Usage
+
+To add a HTTP proxy for the API client, use `ClientConfig`:
+```java
+
+import org.glassfish.jersey.apache.connector.ApacheConnectorProvider;
+import org.glassfish.jersey.client.ClientConfig;
+import org.glassfish.jersey.client.ClientProperties;
+import org.openapitools.client.*;
+import org.openapitools.client.api.PetApi;
+
+...
+
+ApiClient defaultClient = Configuration.getDefaultApiClient();
+ClientConfig clientConfig = defaultClient.getClientConfig();
+clientConfig.connectorProvider(new ApacheConnectorProvider());
+clientConfig.property(ClientProperties.PROXY_URI, "http://proxy_url_here");
+clientConfig.property(ClientProperties.PROXY_USERNAME, "proxy_username");
+clientConfig.property(ClientProperties.PROXY_PASSWORD, "proxy_password");
+defaultClient.setClientConfig(clientConfig);
+
+PetApi apiInstance = new PetApi(defaultClient);
+
+```
+
+## Getting Started
+
+Please follow the [installation](#installation) instruction and execute the following Java code:
+
+```java
+
+import org.openapitools.client.*;
+import org.openapitools.client.auth.*;
+import org.openapitools.client.model.*;
+import org.openapitools.client.api.PetApi;
+
+public class PetApiExample {
+
+    public static void main(String[] args) {
+        ApiClient defaultClient = Configuration.getDefaultApiClient();
+        defaultClient.setBasePath("http://petstore.swagger.io/v2");
+        
+        // Configure OAuth2 access token for authorization: petstore_auth
+        OAuth petstore_auth = (OAuth) defaultClient.getAuthentication("petstore_auth");
+        petstore_auth.setAccessToken("YOUR ACCESS TOKEN");
+
+        PetApi apiInstance = new PetApi(defaultClient);
+        Pet pet = new Pet(); // Pet | Pet object that needs to be added to the store
+        try {
+            Pet result = apiInstance.addPet(pet);
+            System.out.println(result);
+        } catch (ApiException e) {
+            System.err.println("Exception when calling PetApi#addPet");
+            System.err.println("Status code: " + e.getCode());
+            System.err.println("Reason: " + e.getResponseBody());
+            System.err.println("Response headers: " + e.getResponseHeaders());
+            e.printStackTrace();
+        }
+    }
+}
+
+```

+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

Subject: [PATCH 017/352] [Python] pass api_client configuration to model
 deserialize (#13922)

configures logging and determines cpu count every time.
This causes extreme performance issues when deserializing larger sets of
items.

That is, one file will be created per API; APIs are generated defined according to tags in your spec documentation. The destination filename of `Interface.kt` will act as a suffix for the filename. So, a tag of `Equipment` will output a corresponding `EquipmentInterface.kt`.
 * Because `api.mustache` is the same mustache filename as used in your target generator (`kotlin` in this example), we support the following:
   - The destination filename provides a suffix for the generated output. APIs generate per tag in your specification. So, a tag of `Equipment` will output a corresponding `EquipmentImpl.kt`. This option will be used whether `api.mustache` targets a user customized template or a built-in template.
-  - The built-in template will be used if you haven't provided an customized template. The kotlin generator defines the suffix as simply `.kt`, so this scenario would modify only the generated file suffixes according to the previous bullet point.

   - Your `api.mustache` will be used if it exists in your custom template directory. For generators with library options, such as `jvm-okhttp3` in the kotlin generator, your file must exist in the same relative location as the embedded template. For kotlin using the `jvm-okhttp3` library option, this file would need to be located at `my_custom_templates/libraries/jvm-okhttp/api.mustache`. See [templating](./templating.md) for more details.
 * Compile `my_custom_templates/other/check.mustache` with the supporting files bundle, and output to `scripts/check.sh` in your output directory. Note that we don't currently support setting file flags on output, so scripts such as these will either have to be sourced rather than executed, or have file flags set separately after generation (external to our tooling).

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

Subject: [PATCH 038/352] Don't cast list to tuple in python-prior binding
 (#14014)

* Add test for python-prior type conversion error

In the spirit of test driven development, this test intentionally fails.
A following commit will fix the code to comply with the test.

See: https://github.com/OpenAPITools/openapi-generator/issues/14012

* Don't cast list to tuple in python-prior binding

Tweak the python-prior API bindings, so that they no longer cast lists
to tuples when making a POST request with a multipart/form-data
content-type. This fixes an interaction with
`urllib3.request_encode_body`, whose `fields` parameter expects tuples,
not lists.

cc @spacether

See: https://urllib3.readthedocs.io/en/stable/reference/urllib3.request.html

Fix: https://github.com/OpenAPITools/openapi-generator/issues/14012

From 9039c83bc46e5efa42b92f16ed4bed31d27442c1 Mon Sep 17 00:00:00 2001
From: Jeremy Audet <audet.jeremy@pm.me>
Date: Sat, 19 Nov 2022 10:46:42 -0500
Subject: [PATCH 045/352] Migrate python-prior/tests_manual/ to pathlib
 (#14043)

This change has no functional impact. In my view, `pathlib` has a more
pleasant API than `os.path`.  Incidentally, this slightly reduces line
count.

Subject: [PATCH 066/352] [Micronaut] Improving micronaut-model and
 micronaut-client generation (#14065)

* fix documentation

* improve build.gradle.mustache and pom.xml.mustache to assume different serialization libs jackson or micronaut-serde-jackson

* improve pojo.mustache to skip generating @JsonDeserialize as for micronaut-serde-jackson

* improve model generating by removing visible flag from @JsonTypeInfo as it is not supported by micronaut-serde-jackson

Co-authored-by: dmitry.kubakhov <dmitry.kubakhov@check24.de>

From 57644b681788634decacc55e0a1c9c1b792d9bfb Mon Sep 17 00:00:00 2001
From: Clemens Heppner <ch@cheppner.de>
Date: Fri, 25 Nov 2022 09:17:17 +0100
Subject: [PATCH 067/352] Initialization of typeAliases was triggered by
 fromModel(...), which is incorrect. (#14054)

When fromOperation(...) was called before fromModel, the aliases were uninitialized.

(cherry picked from commit 44ea23168362cfacf8a61ff944701990cf3fea76)

 ## Inline Schema Naming
 
-Inline schemas are created as separate schemas automatically and the auto-generated schema name may not look good to everyone. One can customize the name using the `title` field or the `inlineSchemaNameMapping` option, e.g. in CLI
+Inline schemas are created as separate schemas automatically and the auto-generated schema name may not look good to everyone. One can customize the name using the `title` field or the `inlineSchemaNameMapping` option. For exmaple, run the following,
 
 ```
 java -jar modules/openapi-generator-cli/target/openapi-generator-cli.jar generate -g java -i  modules/openapi-generator/src/test/resources/3_0/inline_model_resolver.yaml -o /tmp/java3/ --skip-validate-spec --inline-schema-name-mappings inline_object_2=SomethingMapped,inline_object_4=nothing_new
 ```
+will show the following in the console:
+```
+[main] INFO  o.o.codegen.InlineModelResolver - Inline schema created as arbitraryObjectRequestBodyProperty_request. To have complete control of the model name, set the `title` field or use the inlineSchemaNameMapping option (--inline-schema-name-mappings in CLI).
+[main] INFO  o.o.codegen.InlineModelResolver - Inline schema created as meta_200_response. To have complete control of the model name, set the `title` field or use the inlineSchemaNameMapping option (--inline-schema-name-mappings in CLI).
+```
+For example, to name the inline schema `meta_200_response` as `MetaObject`, use the `--inline-schema-name-mappings` option as follows:
+```
+java -jar modules/openapi-generator-cli/target/openapi-generator-cli.jar generate -g java -i  modules/openapi-generator/src/test/resources/3_0/inline_model_resolver.yaml -o /tmp/java3/ --skip-validate-spec --inline-schema-name-mappings meta_200_response=MetaObject,arbitraryObjectRequestBodyProperty_request=ArbitraryRequest
+```
 
 Another useful option is `inlineSchemaNameDefaults`, which allows you to customize the suffix of the auto-generated inline schema name, e.g. in CLI
 ```

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+Echo Server API
+
+- API version: 0.1.0
+
+Echo Server API
+
+
+*Automatically generated by the [OpenAPI Generator](https://openapi-generator.tech)*
+
+## Requirements
+
+Building the API client library requires:
+
+1. Java 11+
+2. Maven/Gradle
+
+## Installation
+
+To install the API client library to your local Maven repository, simply execute:
+
+```shell
+mvn clean install
+```
+
+To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:
+
+```shell
+mvn clean deploy
+```
+
+Refer to the [OSSRH Guide](http://central.sonatype.org/pages/ossrh-guide.html) for more information.
+
+### Maven users
+
+Add this dependency to your project's POM:
+
+```xml
+<dependency>
+  <groupId>org.openapitools</groupId>
+  <artifactId>echo-api-native</artifactId>
+  <version>0.1.0</version>
+  <scope>compile</scope>
+</dependency>
+```
+
+### Gradle users
+
+Add this dependency to your project's build file:
+
+```groovy
+compile "org.openapitools:echo-api-native:0.1.0"
+```
+
+### Others
+
+At first generate the JAR by executing:
+
+```shell
+mvn clean package
+```
+
+Then manually install the following JARs:
+
+- `target/echo-api-native-0.1.0.jar`
+- `target/lib/*.jar`
+
+## Getting Started
+
+Please follow the [installation](#installation) instruction and execute the following Java code:
+
+```java
+
+import org.openapitools.client.*;
+import org.openapitools.client.model.*;
+import org.openapitools.client.api.QueryApi;
+
+public class QueryApiExample {
+
+    public static void main(String[] args) {
+        ApiClient defaultClient = Configuration.getDefaultApiClient();
+        // Configure clients using the `defaultClient` object, such as
+        // overriding the host and port, timeout, etc.
+        QueryApi apiInstance = new QueryApi(defaultClient);
+        TestQueryStyleFormExplodeTrueArrayStringQueryObjectParameter queryObject = new HashMap(); // TestQueryStyleFormExplodeTrueArrayStringQueryObjectParameter | 
+        try {
+            String result = apiInstance.testQueryStyleFormExplodeTrueArrayString(queryObject);
+            System.out.println(result);
+        } catch (ApiException e) {
+            System.err.println("Exception when calling QueryApi#testQueryStyleFormExplodeTrueArrayString");
+            System.err.println("Status code: " + e.getCode());
+            System.err.println("Reason: " + e.getResponseBody());
+            System.err.println("Response headers: " + e.getResponseHeaders());
+            e.printStackTrace();
+        }
+    }
+}
+
+```

+ - [Pet](docs/Pet.md)
+ - [Tag](docs/Tag.md)
+ - [TestQueryStyleFormExplodeTrueArrayStringQueryObjectParameter](docs/TestQueryStyleFormExplodeTrueArrayStringQueryObjectParameter.md)
+
+
+## Documentation for Authorization
+
+All endpoints do not require authorization.
+Authentication schemes defined for the API:
+
+## Recommendation
+
+It's recommended to create an instance of `ApiClient` per thread in a multithreaded environment to avoid any potential issues.
+However, the instances of the api clients created from the `ApiClient` are thread-safe and can be re-used.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

-##  Gradle start up script for UN*X
-##
+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

Subject: [PATCH 088/352] [typescript-fetch] Fix response type to be Response
 or undefined (#13825)

* Fix response type to be Response or undefined

Current generated code produces a `response` variable set to undefined, and TS does not like you changing the type of the variable later. Therefore, set the type of the variable to be `Response` or `undefined`

Solves OpenAPITools/openapi-generator#12007

* Update samples

* Changes manually cherry-picked (for the most part) from https://github.com/OpenAPITools/openapi-generator/pull/12685/files

* Examples updated post changes

* Missed a change in the mustache template

* Update examples after last fix

* Missed dereference for required files

* Update unit tests

* Missed another test case update

* `f := *f` isn't quite the same as `*f, err = ...`

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+        defaultClient.setBasePath("http://localhost:3000");
+        
+        PathApi apiInstance = new PathApi(defaultClient);
+        String pathString = "pathString_example"; // String | 
+        Integer pathInteger = 56; // Integer | 
+        try {
+            String result = apiInstance.testsPathStringPathStringIntegerPathInteger(pathString, pathInteger);
+            System.out.println(result);
+        } catch (ApiException e) {

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
+#
+#       You can find Gradle at https://github.com/gradle/gradle/.

+*    To mock the client, use the generic AddApiHttpClients.
+*    To mock the server, change the client's BaseAddress.
+*
+* 3. Locate the test you want below
+*      - remove the skip property from the Fact attribute
+*      - set the value of any variables if necessary
+*
+* 4. Run the tests and ensure they work.

-## Questions
-
-- What about HttpRequest failures and retries?
-  If supportsRetry is enabled, you can configure Polly in the ConfigureClients method.
-- How are tokens used?
-  Tokens are provided by a TokenProvider class. The default is RateLimitProvider which will perform client side rate limiting.
-  Other providers can be used with the UseProvider method.
-- Does an HttpRequest throw an error when the server response is not Ok?
-  It depends how you made the request. If the return type is ApiResponse<T> no error will be thrown, though the Content property will be null. 
-  StatusCode and ReasonPhrase will contain information about the error.
-  If the return type is T, then it will throw. If the return type is TOrDefault, it will return null.

+## Questions
+
+- What about HttpRequest failures and retries?
+  If supportsRetry is enabled, you can configure Polly in the ConfigureClients method.
+- How are tokens used?
+  Tokens are provided by a TokenProvider class. The default is RateLimitProvider which will perform client side rate limiting.
+  Other providers can be used with the UseProvider method.
+- Does an HttpRequest throw an error when the server response is not Ok?
+  It depends how you made the request. If the return type is ApiResponse<T> no error will be thrown, though the Content property will be null. 
+  StatusCode and ReasonPhrase will contain information about the error.
+  If the return type is T, then it will throw. If the return type is TOrDefault, it will return null.
+- How do I validate requests and process responses?
+  Use the provided On and After methods in the Api class from the namespace Org.OpenAPITools.Rest.DefaultApi.
+  Or provide your own class by using the generic ConfigureApi method.

-## Questions
-
-- What about HttpRequest failures and retries?
-  If supportsRetry is enabled, you can configure Polly in the ConfigureClients method.
-- How are tokens used?
-  Tokens are provided by a TokenProvider class. The default is RateLimitProvider which will perform client side rate limiting.
-  Other providers can be used with the UseProvider method.
-- Does an HttpRequest throw an error when the server response is not Ok?
-  It depends how you made the request. If the return type is ApiResponse<T> no error will be thrown, though the Content property will be null. 
-  StatusCode and ReasonPhrase will contain information about the error.
-  If the return type is T, then it will throw. If the return type is TOrDefault, it will return null.

+## Questions
+
+- What about HttpRequest failures and retries?
+  If supportsRetry is enabled, you can configure Polly in the ConfigureClients method.
+- How are tokens used?
+  Tokens are provided by a TokenProvider class. The default is RateLimitProvider which will perform client side rate limiting.
+  Other providers can be used with the UseProvider method.
+- Does an HttpRequest throw an error when the server response is not Ok?
+  It depends how you made the request. If the return type is ApiResponse<T> no error will be thrown, though the Content property will be null. 
+  StatusCode and ReasonPhrase will contain information about the error.
+  If the return type is T, then it will throw. If the return type is TOrDefault, it will return null.
+- How do I validate requests and process responses?
+  Use the provided On and After methods in the Api class from the namespace Org.OpenAPITools.Rest.DefaultApi.
+  Or provide your own class by using the generic ConfigureApi method.

-## Questions
-
-- What about HttpRequest failures and retries?
-  If supportsRetry is enabled, you can configure Polly in the ConfigureClients method.
-- How are tokens used?
-  Tokens are provided by a TokenProvider class. The default is RateLimitProvider which will perform client side rate limiting.
-  Other providers can be used with the UseProvider method.
-- Does an HttpRequest throw an error when the server response is not Ok?
-  It depends how you made the request. If the return type is ApiResponse<T> no error will be thrown, though the Content property will be null. 
-  StatusCode and ReasonPhrase will contain information about the error.
-  If the return type is T, then it will throw. If the return type is TOrDefault, it will return null.

+## Questions
+
+- What about HttpRequest failures and retries?
+  If supportsRetry is enabled, you can configure Polly in the ConfigureClients method.
+- How are tokens used?
+  Tokens are provided by a TokenProvider class. The default is RateLimitProvider which will perform client side rate limiting.
+  Other providers can be used with the UseProvider method.
+- Does an HttpRequest throw an error when the server response is not Ok?
+  It depends how you made the request. If the return type is ApiResponse<T> no error will be thrown, though the Content property will be null. 
+  StatusCode and ReasonPhrase will contain information about the error.
+  If the return type is T, then it will throw. If the return type is TOrDefault, it will return null.
+- How do I validate requests and process responses?
+  Use the provided On and After methods in the Api class from the namespace Org.OpenAPITools.Rest.DefaultApi.
+  Or provide your own class by using the generic ConfigureApi method.

Subject: [PATCH 111/352] Add support for Angular v15 (#14231)

* Add support for Angular v15

Support for:

- rxjs 7.5.5
- ngPackagr 15.0.2
- zonejs 0.11.5
- typescript >=4.8.2 and <4.10.0

Note that tsTickle is not added to the dependencies when generating for
Angular 15, as:
- it is not a real dependency
- tsTickle is compatible with any of the TypeScript versions that
  Angular 15 supports.

* Generate samples for Angular v15

- typescript-angular-v15-provided-in-root
- typescript-angular-v15-query-param-object-format

* Drop sample typescript-angular-v15-query-param-object-format

* Fix typo

* Add tests for sample

Use credentials instead of api_key to avoid deprecation warnings when
initialising ConfigurationParameters.

* Update samples/client/petstore/typescript-angular-v15-provided-in-root/package.json

* Fix tests by removing context initialisation

Also updated the test dependencies.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+
+
+#### General usage
+
+In your Angular project:
+
+
+```
+// without configuring providers
+import { ApiModule } from '';
+import { HttpClientModule } from '@angular/common/http';
+
+@NgModule({
+    imports: [
+        ApiModule,
+        // make sure to import the HttpClientModule in the AppModule only,
+        // see https://github.com/angular/angular/issues/20575
+        HttpClientModule
+    ],
+    declarations: [ AppComponent ],
+    providers: [],
+    bootstrap: [ AppComponent ]
+})
+export class AppModule {}
+```
+
+```
+// configuring providers
+import { ApiModule, Configuration, ConfigurationParameters } from '';
+
+export function apiConfigFactory (): Configuration {
+  const params: ConfigurationParameters = {
+    // set configuration parameters here.
+  }
+  return new Configuration(params);
+}
+
+@NgModule({
+    imports: [ ApiModule.forRoot(apiConfigFactory) ],
+    declarations: [ AppComponent ],
+    providers: [],
+    bootstrap: [ AppComponent ]
+})
+export class AppModule {}
+```
+
+```
+// configuring providers with an authentication service that manages your access tokens
+import { ApiModule, Configuration } from '';
+
+@NgModule({
+    imports: [ ApiModule ],
+    declarations: [ AppComponent ],
+    providers: [
+      {
+        provide: Configuration,
+        useFactory: (authService: AuthService) => new Configuration(
+          {
+            basePath: environment.apiUrl,
+            accessToken: authService.getAccessToken.bind(authService)
+          }
+        ),
+        deps: [AuthService],
+        multi: false
+      }
+    ],
+    bootstrap: [ AppComponent ]
+})
+export class AppModule {}
+```
+
+```
+import { DefaultApi } from '';
+
+export class AppComponent {
+    constructor(private apiGateway: DefaultApi) { }
+}
+```
+
+Note: The ApiModule is restricted to being instantiated once app wide.
+This is to ensure that all services are treated as singletons.
+
+#### Using multiple OpenAPI files / APIs / ApiModules
+In order to use multiple `ApiModules` generated from different OpenAPI files,
+you can create an alias name when importing the modules
+in order to avoid naming conflicts:
+```
+import { ApiModule } from 'my-api-path';
+import { ApiModule as OtherApiModule } from 'my-other-api-path';
+import { HttpClientModule } from '@angular/common/http';
+
+@NgModule({
+  imports: [
+    ApiModule,
+    OtherApiModule,
+    // make sure to import the HttpClientModule in the AppModule only,
+    // see https://github.com/angular/angular/issues/20575
+    HttpClientModule
+  ]
+})
+export class AppModule {
+
+}
+```
+
+
+### Set service base path
+If different than the generated base path, during app bootstrap, you can provide the base path to your service.
+
+```
+import { BASE_PATH } from '';
+
+bootstrap(AppComponent, [
+    { provide: BASE_PATH, useValue: 'https://your-web-service.com' },
+]);
+```
+or
+
+```
+import { BASE_PATH } from '';
+
+@NgModule({
+    imports: [],
+    declarations: [ AppComponent ],
+    providers: [ provide: BASE_PATH, useValue: 'https://your-web-service.com' ],
+    bootstrap: [ AppComponent ]
+})
+export class AppModule {}
+```
+
+
+#### Using @angular/cli
+First extend your `src/environments/*.ts` files by adding the corresponding base path:
+
+```
+export const environment = {
+  production: false,
+  API_BASE_PATH: 'http://127.0.0.1:8080'
+};
+```
+
+In the src/app/app.module.ts:
+```
+import { BASE_PATH } from '';
+import { environment } from '../environments/environment';
+
+@NgModule({
+  declarations: [
+    AppComponent
+  ],
+  imports: [ ],
+  providers: [{ provide: BASE_PATH, useValue: environment.API_BASE_PATH }],
+  bootstrap: [ AppComponent ]
+})
+export class AppModule { }
+```
+
+### Customizing path parameter encoding
+
+Without further customization, only [path-parameters][parameter-locations-url] of [style][style-values-url] 'simple'
+and Dates for format 'date-time' are encoded correctly.
+
+Other styles (e.g. "matrix") are not that easy to encode
+and thus are best delegated to other libraries (e.g.: [@honoluluhenk/http-param-expander]).
+
+To implement your own parameter encoding (or call another library),
+pass an arrow-function or method-reference to the `encodeParam` property of the Configuration-object
+(see [General Usage](#general-usage) above).
+
+Example value for use in your Configuration-Provider:
+```typescript
+new Configuration({
+    encodeParam: (param: Param) => myFancyParamEncoder(param),
+})
+```

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+
+## Requirements
+
+Building the API client library requires [Maven](https://maven.apache.org/) to be installed.
+
+## Installation & Usage
+
+To install the API client library to your local Maven repository, simply execute:
+
+```shell
+mvn install
+```
+
+To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:
+
+```shell
+mvn deploy
+```
+
+Refer to the [official documentation](https://maven.apache.org/plugins/maven-deploy-plugin/usage.html) for more information.
+
+After the client library is installed/deployed, you can use it in your Maven project by adding the following to your *pom.xml*:
+
+```xml
+<dependency>
+    <groupId>org.openapitools</groupId>
+    <artifactId>echo-api-feign-json</artifactId>
+    <version>0.1.0</version>
+    <scope>compile</scope>
+</dependency>
+
+```
+
+And to use the api you can follow the examples bellow:
+
+```java
+
+    //Set bearer token manually
+    ApiClient apiClient = new ApiClient("petstore_auth_client");
+    apiClient.setBasePath("https://localhost:8243/petstore/1/");
+    apiClient.setAccessToken("TOKEN", 10000);
+
+    //Use api key
+    ApiClient apiClient = new ApiClient("api_key", "API KEY");
+    apiClient.setBasePath("https://localhost:8243/petstore/1/");
+
+    //Use http basic authentication
+    ApiClient apiClient = new ApiClient("basicAuth");
+    apiClient.setBasePath("https://localhost:8243/petstore/1/");
+    apiClient.setCredentials("username", "password");
+
+    //Oauth password
+    ApiClient apiClient = new ApiClient("oauth_password");
+    apiClient.setBasePath("https://localhost:8243/petstore/1/");
+    apiClient.setOauthPassword("username", "password", "client_id", "client_secret");
+
+    //Oauth client credentials flow
+    ApiClient apiClient = new ApiClient("oauth_client_credentials");
+    apiClient.setBasePath("https://localhost:8243/petstore/1/");
+    apiClient.setClientCredentials("client_id", "client_secret");
+
+    PetApi petApi = apiClient.buildClient(PetApi.class);
+    Pet petById = petApi.getPetById(12345L);
+
+    System.out.println(petById);
+  }
+```
+
+## Recommendation
+
+It's recommended to create an instance of `ApiClient` per thread in a multithreaded environment to avoid any potential issues.

+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
+#

+    :param api_key_prefix: Dict to store API prefix (e.g. Bearer).
+      The dict key is the name of the security scheme in the OAS specification.
+      The dict value is an API key prefix when generating the auth data.
+    :param username: Username for HTTP basic authentication.
+    :param password: Password for HTTP basic authentication.
+    :param discard_unknown_keys: Boolean value indicating whether to discard
+      unknown properties. A server may send a response that includes additional
+      properties that are not known by the client in the following scenarios:
+      1. The OpenAPI document is incomplete, i.e. it does not match the server
+         implementation.
+      2. The client was generated using an older version of the OpenAPI document
+         and the server has been upgraded since then.
+      If a schema in the OpenAPI document defines the additionalProperties attribute,
+      then all undeclared properties received by the server are injected into the

+      rules. The following keywords may be specified: multipleOf, maximum,
+      exclusiveMaximum, minimum, exclusiveMinimum, maxLength, minLength, pattern,
+      maxItems, minItems.
+      By default, the validation is performed for data generated locally by the client
+      and data received from the server, independent of any validation performed by
+      the server side. If the input data does not satisfy the JSON schema validation
+      rules specified in the OpenAPI document, an exception is raised.
+      If disabled_client_side_validations is set, structural validation is
+      disabled. This can be useful to troubleshoot data validation problem, such as
+      when the OpenAPI document validation rules do not match the actual API data
+      received by the server.

+          http_basic_auth:
+            type: http

+
+    Configure API client with HTTP signature authentication. Use the 'hs2019' signature scheme,
+    sign the HTTP requests with the RSA-SSA-PSS signature algorithm, and set the expiration time
+    of the signature to 5 minutes after the signature has been created.
+    Note you can use the constants defined in the {{{packageName}}}.signing module, and you can
+    also specify arbitrary HTTP headers to be included in the HTTP signature, except for the
+    'Authorization' header, which is used to carry the signature.
+
+    One may be tempted to sign all headers by default, but in practice it rarely works.
+    This is because explicit proxies, transparent proxies, TLS termination endpoints or
+    load balancers may add/modify/remove headers. Include the HTTP headers that you know
+    are not going to be modified in transit.

+    """The configuration parameters for the HTTP signature security scheme.
+    The HTTP signature security scheme is used to sign HTTP requests with a private key
+    which is in possession of the API client.
+    An 'Authorization' header is calculated by creating a hash of select headers,
+    and optionally the body of the HTTP request, then signing the hash value using
+    a private key. The 'Authorization' header is added to outbound HTTP requests.

+
+    :param key_id: A string value specifying the identifier of the cryptographic key,
+        when signing HTTP requests.
+    :param signing_scheme: A string value specifying the signature scheme, when
+        signing HTTP requests.
+        Supported value are hs2019, rsa-sha256, rsa-sha512.
+        Avoid using rsa-sha256, rsa-sha512 as they are deprecated. These values are
+        available for server-side applications that only support the older
+        HTTP signature algorithms.
+    :param private_key_path: A string value specifying the path of the file containing
+        a private key. The private key is used to sign HTTP requests.
+    :param private_key_passphrase: A string value specifying the passphrase to decrypt
+        the private key.
+    :param signed_headers: A list of strings. Each value is the name of a HTTP header
+        that must be included in the HTTP signature calculation.
+        The two special signature headers '(request-target)' and '(created)' SHOULD be
+        included in SignedHeaders.
+        The '(created)' header expresses when the signature was created.
+        The '(request-target)' header is a concatenation of the lowercased :method, an
+        ASCII space, and the :path pseudo-headers.
+        When signed_headers is not specified, the client defaults to a single value,
+        '(created)', in the list of HTTP headers.
+        When SignedHeaders contains the 'Digest' value, the client performs the
+        following operations:
+        1. Calculate a digest of request body, as specified in RFC3230, section 4.3.2.
+        2. Set the 'Digest' header in the request body.
+        3. Include the 'Digest' header and value in the HTTP signature.
+    :param signing_algorithm: A string value specifying the signature algorithm, when
+        signing HTTP requests.
+        Supported values are:
+        1. For RSA keys: RSASSA-PSS, RSASSA-PKCS1-v1_5.
+        2. For ECDSA keys: fips-186-3, deterministic-rfc6979.
+        If None, the signing algorithm is inferred from the private key.
+        The default signing algorithm for RSA keys is RSASSA-PSS.
+        The default signing algorithm for ECDSA keys is fips-186-3.
+    :param hash_algorithm: The hash algorithm for the signature. Supported values are
+        sha256 and sha512.
+        If the signing_scheme is rsa-sha256, the hash algorithm must be set
+        to None or sha256.
+        If the signing_scheme is rsa-sha512, the hash algorithm must be set
+        to None or sha512.
+    :param signature_max_validity: The signature max validity, expressed as
+        a datetime.timedelta value. It must be a positive value.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+### Example

+```python
+from __future__ import print_function
+import time
+import os
+import petstore_api
+from petstore_api.rest import ApiException
+from pprint import pprint
+# Defining the host is optional and defaults to http://petstore.swagger.io:80/v2
+# See configuration.py for a list of all supported configuration parameters.
+configuration = petstore_api.Configuration(
+    host = "http://petstore.swagger.io:80/v2"
+)
+
+# The client must configure the authentication and authorization parameters
+# in accordance with the API server security policy.
+# Examples for each auth method are provided below, use the example that
+# satisfies your auth use case.
+
+# Configure HTTP message signature: http_signature_test
+# The HTTP Signature Header mechanism that can be used by a client to
+# authenticate the sender of a message and ensure that particular headers
+# have not been modified in transit.
+#
+# You can specify the signing key-id, private key path, signing scheme,
+# signing algorithm, list of signed headers and signature max validity.
+# The 'key_id' parameter is an opaque string that the API server can use
+# to lookup the client and validate the signature.
+# The 'private_key_path' parameter should be the path to a file that
+# contains a DER or base-64 encoded private key.
+# The 'private_key_passphrase' parameter is optional. Set the passphrase
+# if the private key is encrypted.
+# The 'signed_headers' parameter is used to specify the list of
+# HTTP headers included when generating the signature for the message.
+# You can specify HTTP headers that you want to protect with a cryptographic
+# signature. Note that proxies may add, modify or remove HTTP headers
+# for legitimate reasons, so you should only add headers that you know
+# will not be modified. For example, if you want to protect the HTTP request
+# body, you can specify the Digest header. In that case, the client calculates
+# the digest of the HTTP request body and includes the digest in the message
+# signature.
+# The 'signature_max_validity' parameter is optional. It is configured as a
+# duration to express when the signature ceases to be valid. The client calculates
+# the expiration date every time it generates the cryptographic signature
+# of an HTTP request. The API server may have its own security policy
+# that controls the maximum validity of the signature. The client max validity
+# must be lower than the server max validity.
+# The time on the client and server must be synchronized, otherwise the
+# server may reject the client signature.
+#
+# The client must use a combination of private key, signing scheme,
+# signing algorithm and hash algorithm that matches the security policy of
+# the API server.

+# body, you can specify the Digest header. In that case, the client calculates
+# the digest of the HTTP request body and includes the digest in the message
+# signature.
+# The 'signature_max_validity' parameter is optional. It is configured as a
+# duration to express when the signature ceases to be valid. The client calculates

+# that controls the maximum validity of the signature. The client max validity
+# must be lower than the server max validity.
+# The time on the client and server must be synchronized, otherwise the

+      The dict key is the name of the security scheme in the OAS specification.
+      The dict value is the API key secret.
+    :param api_key_prefix: Dict to store API prefix (e.g. Bearer).
+      The dict key is the name of the security scheme in the OAS specification.
+      The dict value is an API key prefix when generating the auth data.
+    :param username: Username for HTTP basic authentication.
+    :param password: Password for HTTP basic authentication.
+    :param discard_unknown_keys: Boolean value indicating whether to discard
+      unknown properties. A server may send a response that includes additional
+      properties that are not known by the client in the following scenarios:
+      1. The OpenAPI document is incomplete, i.e. it does not match the server
+         implementation.
+      2. The client was generated using an older version of the OpenAPI document
+         and the server has been upgraded since then.
+      If a schema in the OpenAPI document defines the additionalProperties attribute,
+      then all undeclared properties received by the server are injected into the
+      additional properties map. In that case, there are undeclared properties, and
+      nothing to discard.
+    :param disabled_client_side_validations (string): Comma-separated list of
+      JSON schema validation keywords to disable JSON schema structural validation
+      rules. The following keywords may be specified: multipleOf, maximum,
+      exclusiveMaximum, minimum, exclusiveMinimum, maxLength, minLength, pattern,
+      maxItems, minItems.
+      By default, the validation is performed for data generated locally by the client
+      and data received from the server, independent of any validation performed by
+      the server side. If the input data does not satisfy the JSON schema validation
+      rules specified in the OpenAPI document, an exception is raised.
+      If disabled_client_side_validations is set, structural validation is
+      disabled. This can be useful to troubleshoot data validation problem, such as
+      when the OpenAPI document validation rules do not match the actual API data
+      received by the server.
+    :param signing_info: Configuration parameters for the HTTP signature security scheme.
+        Must be an instance of petstore_api.signing.HttpSigningConfiguration
+    :param server_index: Index to servers configuration.
+    :param server_variables: Mapping with string values to replace variables in
+      templated server configuration. The validation of enums is performed for
+      variables with defined enum values before.
+    :param server_operation_index: Mapping from operation ID to an index to server
+      configuration.
+    :param server_operation_variables: Mapping from operation ID to a mapping with
+      string values to replace variables in templated server configuration.
+      The validation of enums is performed for variables with defined enum values before.

+
+    Configure API client with HTTP signature authentication. Use the 'hs2019' signature scheme,
+    sign the HTTP requests with the RSA-SSA-PSS signature algorithm, and set the expiration time
+    of the signature to 5 minutes after the signature has been created.
+    Note you can use the constants defined in the petstore_api.signing module, and you can
+    also specify arbitrary HTTP headers to be included in the HTTP signature, except for the
+    'Authorization' header, which is used to carry the signature.
+
+    One may be tempted to sign all headers by default, but in practice it rarely works.
+    This is because explicit proxies, transparent proxies, TLS termination endpoints or
+    load balancers may add/modify/remove headers. Include the HTTP headers that you know
+    are not going to be modified in transit.

+        the private key.
+    :param signed_headers: A list of strings. Each value is the name of a HTTP header
+        that must be included in the HTTP signature calculation.
+        The two special signature headers '(request-target)' and '(created)' SHOULD be
+        included in SignedHeaders.
+        The '(created)' header expresses when the signature was created.
+        The '(request-target)' header is a concatenation of the lowercased :method, an
+        ASCII space, and the :path pseudo-headers.
+        When signed_headers is not specified, the client defaults to a single value,
+        '(created)', in the list of HTTP headers.
+        When SignedHeaders contains the 'Digest' value, the client performs the
+        following operations:
+        1. Calculate a digest of request body, as specified in RFC3230, section 4.3.2.
+        2. Set the 'Digest' header in the request body.
+        3. Include the 'Digest' header and value in the HTTP signature.
+    :param signing_algorithm: A string value specifying the signature algorithm, when
+        signing HTTP requests.
+        Supported values are:
+        1. For RSA keys: RSASSA-PSS, RSASSA-PKCS1-v1_5.
+        2. For ECDSA keys: fips-186-3, deterministic-rfc6979.
+        If None, the signing algorithm is inferred from the private key.
+        The default signing algorithm for RSA keys is RSASSA-PSS.
+        The default signing algorithm for ECDSA keys is fips-186-3.
+    :param hash_algorithm: The hash algorithm for the signature. Supported values are
+        sha256 and sha512.
+        If the signing_scheme is rsa-sha256, the hash algorithm must be set
+        to None or sha256.
+        If the signing_scheme is rsa-sha512, the hash algorithm must be set
+        to None or sha512.
+    :param signature_max_validity: The signature max validity, expressed as
+        a datetime.timedelta value. It must be a positive value.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+    client = petstore_api.Client() # Client | client model
+
+    try:
+        # To test special tags
+        api_response = api_instance.call_123_test_special_tags(client)
+        print("The response of AnotherFakeApi->call_123_test_special_tags:\n")
+        pprint(api_response)

+# You can specify the signing key-id, private key path, signing scheme,
+# signing algorithm, list of signed headers and signature max validity.
+# The 'key_id' parameter is an opaque string that the API server can use
+# to lookup the client and validate the signature.
+# The 'private_key_path' parameter should be the path to a file that
+# contains a DER or base-64 encoded private key.
+# The 'private_key_passphrase' parameter is optional. Set the passphrase
+# if the private key is encrypted.
+# The 'signed_headers' parameter is used to specify the list of
+# HTTP headers included when generating the signature for the message.
+# You can specify HTTP headers that you want to protect with a cryptographic
+# signature. Note that proxies may add, modify or remove HTTP headers
+# for legitimate reasons, so you should only add headers that you know
+# will not be modified. For example, if you want to protect the HTTP request
+# body, you can specify the Digest header. In that case, the client calculates
+# the digest of the HTTP request body and includes the digest in the message
+# signature.
+# The 'signature_max_validity' parameter is optional. It is configured as a
+# duration to express when the signature ceases to be valid. The client calculates
+# the expiration date every time it generates the cryptographic signature
+# of an HTTP request. The API server may have its own security policy
+# that controls the maximum validity of the signature. The client max validity
+# must be lower than the server max validity.
+# The time on the client and server must be synchronized, otherwise the
+# server may reject the client signature.
+#

+# The HTTP Signature Header mechanism that can be used by a client to
+# authenticate the sender of a message and ensure that particular headers
+# have not been modified in transit.
+#
+# You can specify the signing key-id, private key path, signing scheme,
+# signing algorithm, list of signed headers and signature max validity.
+# The 'key_id' parameter is an opaque string that the API server can use
+# to lookup the client and validate the signature.
+# The 'private_key_path' parameter should be the path to a file that
+# contains a DER or base-64 encoded private key.
+# The 'private_key_passphrase' parameter is optional. Set the passphrase
+# if the private key is encrypted.
+# The 'signed_headers' parameter is used to specify the list of
+# HTTP headers included when generating the signature for the message.
+# You can specify HTTP headers that you want to protect with a cryptographic
+# signature. Note that proxies may add, modify or remove HTTP headers
+# for legitimate reasons, so you should only add headers that you know
+# will not be modified. For example, if you want to protect the HTTP request
+# body, you can specify the Digest header. In that case, the client calculates
+# the digest of the HTTP request body and includes the digest in the message
+# signature.
+# The 'signature_max_validity' parameter is optional. It is configured as a
+# duration to express when the signature ceases to be valid. The client calculates
+# the expiration date every time it generates the cryptographic signature
+# of an HTTP request. The API server may have its own security policy
+# that controls the maximum validity of the signature. The client max validity
+# must be lower than the server max validity.
+# The time on the client and server must be synchronized, otherwise the
+# server may reject the client signature.

+      The dict key is the name of the security scheme in the OAS specification.
+      The dict value is the API key secret.
+    :param api_key_prefix: Dict to store API prefix (e.g. Bearer).
+      The dict key is the name of the security scheme in the OAS specification.
+      The dict value is an API key prefix when generating the auth data.
+    :param username: Username for HTTP basic authentication.
+    :param password: Password for HTTP basic authentication.
+    :param discard_unknown_keys: Boolean value indicating whether to discard
+      unknown properties. A server may send a response that includes additional
+      properties that are not known by the client in the following scenarios:
+      1. The OpenAPI document is incomplete, i.e. it does not match the server
+         implementation.
+      2. The client was generated using an older version of the OpenAPI document
+         and the server has been upgraded since then.
+      If a schema in the OpenAPI document defines the additionalProperties attribute,
+      then all undeclared properties received by the server are injected into the
+      additional properties map. In that case, there are undeclared properties, and
+      nothing to discard.

+      rules. The following keywords may be specified: multipleOf, maximum,

+      maxItems, minItems.
+      By default, the validation is performed for data generated locally by the client
+      and data received from the server, independent of any validation performed by
+      the server side. If the input data does not satisfy the JSON schema validation
+      rules specified in the OpenAPI document, an exception is raised.
+      If disabled_client_side_validations is set, structural validation is
+      disabled. This can be useful to troubleshoot data validation problem, such as
+      when the OpenAPI document validation rules do not match the actual API data
+      received by the server.
+    :param signing_info: Configuration parameters for the HTTP signature security scheme.
+        Must be an instance of petstore_api.signing.HttpSigningConfiguration
+    :param server_index: Index to servers configuration.
+    :param server_variables: Mapping with string values to replace variables in
+      templated server configuration. The validation of enums is performed for
+      variables with defined enum values before.
+    :param server_operation_index: Mapping from operation ID to an index to server

+    api_key_prefix={'cookieAuth': 'JSESSIONID'}

+
+    Configure API client with HTTP signature authentication. Use the 'hs2019' signature scheme,
+    sign the HTTP requests with the RSA-SSA-PSS signature algorithm, and set the expiration time
+    of the signature to 5 minutes after the signature has been created.
+    Note you can use the constants defined in the petstore_api.signing module, and you can
+    also specify arbitrary HTTP headers to be included in the HTTP signature, except for the
+    'Authorization' header, which is used to carry the signature.
+
+    One may be tempted to sign all headers by default, but in practice it rarely works.
+    This is because explicit proxies, transparent proxies, TLS termination endpoints or
+    load balancers may add/modify/remove headers. Include the HTTP headers that you know
+    are not going to be modified in transit.

+    """The configuration parameters for the HTTP signature security scheme.
+    The HTTP signature security scheme is used to sign HTTP requests with a private key
+    which is in possession of the API client.
+    An 'Authorization' header is calculated by creating a hash of select headers,
+    and optionally the body of the HTTP request, then signing the hash value using
+    a private key. The 'Authorization' header is added to outbound HTTP requests.

+
+    :param key_id: A string value specifying the identifier of the cryptographic key,
+        when signing HTTP requests.
+    :param signing_scheme: A string value specifying the signature scheme, when
+        signing HTTP requests.
+        Supported value are hs2019, rsa-sha256, rsa-sha512.
+        Avoid using rsa-sha256, rsa-sha512 as they are deprecated. These values are
+        available for server-side applications that only support the older
+        HTTP signature algorithms.
+    :param private_key_path: A string value specifying the path of the file containing
+        a private key. The private key is used to sign HTTP requests.
+    :param private_key_passphrase: A string value specifying the passphrase to decrypt
+        the private key.
+    :param signed_headers: A list of strings. Each value is the name of a HTTP header
+        that must be included in the HTTP signature calculation.
+        The two special signature headers '(request-target)' and '(created)' SHOULD be
+        included in SignedHeaders.
+        The '(created)' header expresses when the signature was created.
+        The '(request-target)' header is a concatenation of the lowercased :method, an
+        ASCII space, and the :path pseudo-headers.
+        When signed_headers is not specified, the client defaults to a single value,
+        '(created)', in the list of HTTP headers.
+        When SignedHeaders contains the 'Digest' value, the client performs the
+        following operations:
+        1. Calculate a digest of request body, as specified in RFC3230, section 4.3.2.
+        2. Set the 'Digest' header in the request body.
+        3. Include the 'Digest' header and value in the HTTP signature.
+    :param signing_algorithm: A string value specifying the signature algorithm, when
+        signing HTTP requests.
+        Supported values are:
+        1. For RSA keys: RSASSA-PSS, RSASSA-PKCS1-v1_5.
+        2. For ECDSA keys: fips-186-3, deterministic-rfc6979.
+        If None, the signing algorithm is inferred from the private key.
+        The default signing algorithm for RSA keys is RSASSA-PSS.
+        The default signing algorithm for ECDSA keys is fips-186-3.
+    :param hash_algorithm: The hash algorithm for the signature. Supported values are
+        sha256 and sha512.
+        If the signing_scheme is rsa-sha256, the hash algorithm must be set
+        to None or sha256.
+        If the signing_scheme is rsa-sha512, the hash algorithm must be set
+        to None or sha512.
+    :param signature_max_validity: The signature max validity, expressed as
+        a datetime.timedelta value. It must be a positive value.

Subject: [PATCH 124/352] Update Java/Feign api.mustache to accept its own
 convinience Map Class (#14008)

* Update Java/Feign api.mustache to accept convinience Map

Hi, I just saw, that the generated Map Class is never used outside of tests, but it would be the perfect fit for the changed mehods, as its use-case is exactly the same.

Also a useful change to prevent problems with Collection types and their generics parameters (f.e. Map<x, y>). See: https://stackoverflow.com/questions/62823341/openapi-generator-maven-plugin-breaks-old-feign-with-querymap

* PR checklist

Steps as requested per checklist: done.

Subject: [PATCH 125/352] Enable access token refresh (#14251)

* Enable the ruby client to support refreshing access tokens

- The client can now be configured with an access token getter proc
- The proc overrides the the static access token if it is set

* Run generators

Subject: [PATCH 128/352] typescript-nestjs / Ensure default headers remain
 unmodified (#14312)

When sending a request with a client generated by typescript-nestjs, the
default headers are modified. This occurs when headers such as "Accept"
are appended by the client.
The root of the issue is that a reference to the default headers is
stored instead of a clone.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

Subject: [PATCH 144/352] [rust] Fix declaration for arrays with object and
 array references (#14198)

* [rust] Fix declaration for arrays with object and array references

For arrays with an item defined by reference to an array or an object,
the generated type declaration was `Vec<core::models::Array>` or
`Vec<core::models::Map>` without defining a `Array` or `Map` so that the
code didn't compile.

* [rust] Fix trailing whitespace in petstore definition

+## OpenAPI Normalizer

+OpenAPI Normalizer (off by default) transforms the input OpenAPI doc/spec (which may not perfectly conform to the specification) to make it workable with OpenAPI Generator. Here is a list of rules supported:

+- `REF_AS_PARENT_IN_ALLOF`: when set to `true`, child schemas in `allOf` is considered a parent if it's a `$ref` (instead of inline schema)

+
+Example:
+```
+java -jar modules/openapi-generator-cli/target/openapi-generator-cli.jar generate -g java -i modules/openapi-generator/src/test/resources/3_0/allOf_extension_parent.yaml -o /tmp/java-okhttp/ --additional-properties hideGenerationTimestamp="true" --openapi-normalizer REF_AS_PARENT_IN_ALLOF=true

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+
+## Installation
+
+To install the API client library to your local Maven repository, simply execute:
+
+```shell
+mvn clean install
+```
+
+To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:
+
+```shell
+mvn clean deploy
+```

+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
+#
+#       You can find Gradle at https://github.com/gradle/gradle/.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+OpenAPI Petstore
+
+- API version: 1.0.0
+
+This spec is mainly for testing Petstore server and contains fake endpoints, models. Please do not use this for any other purpose. Special characters: \" \\
+
+
+*Automatically generated by the [OpenAPI Generator](https://openapi-generator.tech)*
+
+## Requirements
+
+Building the API client library requires:
+
+1. Java 1.8+
+2. Maven/Gradle
+
+## Installation
+
+To install the API client library to your local Maven repository, simply execute:
+
+```shell
+mvn clean install
+```
+
+To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:
+
+```shell
+mvn clean deploy
+```
+
+Refer to the [OSSRH Guide](http://central.sonatype.org/pages/ossrh-guide.html) for more information.
+
+### Maven users
+
+Add this dependency to your project's POM:
+
+```xml
+<dependency>
+  <groupId>org.openapitools</groupId>
+  <artifactId>petstore-webclient</artifactId>
+  <version>1.0.0</version>
+  <scope>compile</scope>
+</dependency>
+```
+
+### Gradle users
+
+Add this dependency to your project's build file:
+
+```groovy
+  repositories {
+    mavenCentral()     // Needed if the 'petstore-webclient' jar has been published to maven central.
+    mavenLocal()       // Needed if the 'petstore-webclient' jar has been published to the local maven repo.
+  }
+
+  dependencies {
+     implementation "org.openapitools:petstore-webclient:1.0.0"
+  }
+```
+
+### Others
+
+At first generate the JAR by executing:
+
+```shell
+mvn clean package
+```
+
+Then manually install the following JARs:
+
+- `target/petstore-webclient-1.0.0.jar`
+- `target/lib/*.jar`
+
+## Getting Started
+
+Please follow the [installation](#installation) instruction and execute the following Java code:
+
+```java
+
+import org.openapitools.client.*;
+import org.openapitools.client.auth.*;
+import org.openapitools.client.model.*;
+import org.openapitools.client.api.AnotherFakeApi;
+
+public class AnotherFakeApiExample {
+
+    public static void main(String[] args) {
+        ApiClient defaultClient = Configuration.getDefaultApiClient();
+        defaultClient.setBasePath("http://petstore.swagger.io:80/v2");
+        
+        AnotherFakeApi apiInstance = new AnotherFakeApi(defaultClient);
+        Client client = new Client(); // Client | client model
+        try {
+            Client result = apiInstance.call123testSpecialTags(client);
+            System.out.println(result);
+        } catch (ApiException e) {
+            System.err.println("Exception when calling AnotherFakeApi#call123testSpecialTags");
+            System.err.println("Status code: " + e.getCode());
+            System.err.println("Reason: " + e.getResponseBody());
+            System.err.println("Response headers: " + e.getResponseHeaders());
+            e.printStackTrace();
+        }
+    }
+}

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+<a name="questions"></a>
+## Questions
+
+- What about HttpRequest failures and retries?
+  If supportsRetry is enabled, you can configure Polly in the ConfigureClients method.
+- How are tokens used?
+  Tokens are provided by a TokenProvider class. The default is RateLimitProvider which will perform client side rate limiting.
+  Other providers can be used with the UseProvider method.
+- Does an HttpRequest throw an error when the server response is not Ok?
+  It depends how you made the request. If the return type is ApiResponse<T> no error will be thrown, though the Content property will be null. 
+  StatusCode and ReasonPhrase will contain information about the error.
+  If the return type is T, then it will throw. If the return type is TOrDefault, it will return null.
+- How do I validate requests and process responses?
+  Use the provided On and After methods in the Api class from the namespace Org.OpenAPITools.Rest.DefaultApi.
+  Or provide your own class by using the generic ConfigureApi method.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+## Questions
+
+- What about HttpRequest failures and retries?
+  If supportsRetry is enabled, you can configure Polly in the ConfigureClients method.
+- How are tokens used?
+  Tokens are provided by a TokenProvider class. The default is RateLimitProvider which will perform client side rate limiting.
+  Other providers can be used with the UseProvider method.
+- Does an HttpRequest throw an error when the server response is not Ok?
+  It depends how you made the request. If the return type is ApiResponse<T> no error will be thrown, though the Content property will be null. 
+  StatusCode and ReasonPhrase will contain information about the error.
+  If the return type is T, then it will throw. If the return type is TOrDefault, it will return null.
+- How do I validate requests and process responses?
+  Use the provided On and After methods in the Api class from the namespace Org.OpenAPITools.Rest.DefaultApi.
+  Or provide your own class by using the generic ConfigureApi method.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+## Questions
+
+- What about HttpRequest failures and retries?
+  If supportsRetry is enabled, you can configure Polly in the ConfigureClients method.
+- How are tokens used?
+  Tokens are provided by a TokenProvider class. The default is RateLimitProvider which will perform client side rate limiting.
+  Other providers can be used with the UseProvider method.
+- Does an HttpRequest throw an error when the server response is not Ok?
+  It depends how you made the request. If the return type is ApiResponse<T> no error will be thrown, though the Content property will be null. 
+  StatusCode and ReasonPhrase will contain information about the error.
+  If the return type is T, then it will throw. If the return type is TOrDefault, it will return null.
+- How do I validate requests and process responses?
+  Use the provided On and After methods in the Api class from the namespace Org.OpenAPITools.Rest.DefaultApi.
+  Or provide your own class by using the generic ConfigureApi method.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+```
+
+To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:
+
+```shell
+mvn clean deploy
+```
+
+Refer to the [OSSRH Guide](http://central.sonatype.org/pages/ossrh-guide.html) for more information.

+
+public class PetApiExample {
+
+    public static void main(String[] args) {
+        ApiClient defaultClient = Configuration.getDefaultApiClient();
+        // Configure clients using the `defaultClient` object, such as
+        // overriding the host and port, timeout, etc.
+        PetApi apiInstance = new PetApi(defaultClient);
+        Pet pet = new Pet(); // Pet | Pet object that needs to be added to the store
+        try {
+            Pet result = apiInstance.addPet(pet);
+            System.out.println(result);
+        } catch (ApiException e) {
+            System.err.println("Exception when calling PetApi#addPet");
+            System.err.println("Status code: " + e.getCode());
+            System.err.println("Reason: " + e.getResponseBody());
+            System.err.println("Response headers: " + e.getResponseHeaders());
+            e.printStackTrace();

+## Documentation for Authorization
+
+Authentication schemes defined for the API:
+### api_key
+
+
+- **Type**: API key
+- **API key parameter name**: api_key
+- **Location**: HTTP header
+
+### petstore_auth
+
+
+- **Type**: OAuth
+- **Flow**: implicit
+- **Authorization URL**: http://petstore.swagger.io/api/oauth/dialog
+- **Scopes**: 
+  - write:pets: modify pets in your account
+  - read:pets: read your pets
+
+
+## Recommendation
+
+It's recommended to create an instance of `ApiClient` per thread in a multithreaded environment to avoid any potential issues.
+However, the instances of the api clients created from the `ApiClient` are thread-safe and can be re-used.

+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
+#
+#       You can find Gradle at https://github.com/gradle/gradle/.

+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:

+OpenAPI Petstore
+- API version: 1.0.0
+
+This is a sample server Petstore server. For this sample, you can use the api key `special-key` to test the authorization filters.
+
+
+*Automatically generated by the [OpenAPI Generator](https://openapi-generator.tech)*
+
+
+## Requirements
+
+Building the API client library requires:
+1. Java 1.8+
+2. Maven (3.8.3+)/Gradle (7.2+)
+
+## Installation
+
+To install the API client library to your local Maven repository, simply execute:
+
+```shell
+mvn clean install
+```
+
+To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:
+
+```shell
+mvn clean deploy
+```
+
+Refer to the [OSSRH Guide](http://central.sonatype.org/pages/ossrh-guide.html) for more information.
+

+  <artifactId>okhttp-gson-awsv4signature</artifactId>
+  <version>1.0.0</version>
+  <scope>compile</scope>
+</dependency>
+```
+
+### Gradle users

+import org.openapitools.client.models.*;
+import org.openapitools.client.api.PetApi;
+
+public class Example {
+  public static void main(String[] args) {
+    ApiClient defaultClient = Configuration.getDefaultApiClient();
+    defaultClient.setBasePath("http://petstore.swagger.io/v2");
+    // Configure AWS Signature V4 authorization
+    defaultClient.setAWS4Configuration("YOUR_ACCESS_KEY", "YOUR_SECRET_KEY", "REGION", "SERVICE")
+    
+    // Configure OAuth2 access token for authorization: petstore_auth
+    OAuth petstore_auth = (OAuth) defaultClient.getAuthentication("petstore_auth");
+    petstore_auth.setAccessToken("YOUR ACCESS TOKEN");
+
+    PetApi apiInstance = new PetApi(defaultClient);
+    Pet pet = new Pet(); // Pet | Pet object that needs to be added to the store
+    try {
+      Pet result = apiInstance.addPet(pet);
+      System.out.println(result);
+    } catch (ApiException e) {
+      System.err.println("Exception when calling PetApi#addPet");
+      System.err.println("Status code: " + e.getCode());
+      System.err.println("Reason: " + e.getResponseBody());
+      System.err.println("Response headers: " + e.getResponseHeaders());

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
+#
+#       You can find Gradle at https://github.com/gradle/gradle/.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+Echo Server API
+- API version: 0.1.0
+
+Echo Server API
+
+
+*Automatically generated by the [OpenAPI Generator](https://openapi-generator.tech)*
+
+
+## Requirements
+
+Building the API client library requires:
+1. Java 1.8+
+2. Maven (3.8.3+)/Gradle (7.2+)
+
+## Installation
+
+To install the API client library to your local Maven repository, simply execute:
+
+```shell
+mvn clean install
+```
+
+To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:
+
+```shell
+mvn clean deploy
+```
+
+Refer to the [OSSRH Guide](http://central.sonatype.org/pages/ossrh-guide.html) for more information.
+
+### Maven users
+
+Add this dependency to your project's POM:
+
+```xml
+<dependency>
+  <groupId>org.openapitools</groupId>
+  <artifactId>echo-api-okhttp-gson</artifactId>
+  <version>0.1.0</version>
+  <scope>compile</scope>
+</dependency>
+```
+
+### Gradle users
+
+Add this dependency to your project's build file:
+
+```groovy
+  repositories {
+    mavenCentral()     // Needed if the 'echo-api-okhttp-gson' jar has been published to maven central.
+    mavenLocal()       // Needed if the 'echo-api-okhttp-gson' jar has been published to the local maven repo.
+  }
+
+  dependencies {
+     implementation "org.openapitools:echo-api-okhttp-gson:0.1.0"
+  }
+```
+
+### Others
+
+At first generate the JAR by executing:
+
+```shell
+mvn clean package
+```
+
+Then manually install the following JARs:
+
+* `target/echo-api-okhttp-gson-0.1.0.jar`
+* `target/lib/*.jar`
+
+## Getting Started
+
+Please follow the [installation](#installation) instruction and execute the following Java code:
+
+```java
+
+// Import classes:
+import org.openapitools.client.ApiClient;
+import org.openapitools.client.ApiException;
+import org.openapitools.client.Configuration;
+import org.openapitools.client.models.*;
+import org.openapitools.client.api.BodyApi;
+
+public class Example {
+  public static void main(String[] args) {
+    ApiClient defaultClient = Configuration.getDefaultApiClient();
+    defaultClient.setBasePath("http://localhost:3000");
+
+    BodyApi apiInstance = new BodyApi(defaultClient);
+    Pet pet = new Pet(); // Pet | Pet object that needs to be added to the store
+    try {
+      Pet result = apiInstance.testEchoBodyPet(pet);
+      System.out.println(result);
+    } catch (ApiException e) {
+      System.err.println("Exception when calling BodyApi#testEchoBodyPet");
+      System.err.println("Status code: " + e.getCode());
+      System.err.println("Reason: " + e.getResponseBody());
+      System.err.println("Response headers: " + e.getResponseHeaders());
+      e.printStackTrace();
+    }
+  }
+}
+
+```

+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
+#

 OpenAPI Normalizer (off by default) transforms the input OpenAPI doc/spec (which may not perfectly conform to the specification) to make it workable with OpenAPI Generator. Here is a list of rules supported:

+- `REF_AS_PARENT_IN_ALLOF`: when set to `true`, child schemas in `allOf` is considered a parent if it's a `$ref` (instead of inline schema).

Subject: [PATCH 208/352] [Go] Client Models using AllOf, OneOf, or AnyOf
 Correctly Include time and os imports (Attempt 2) (#14459)

* Currently, if a Model is an allOf the time and os imports are not correctly added to the generated file. This was introduced recently with a fix to not include those imports when the model is a composedSchema #13833. The logic in that fix was just slightly off as an allOf should be treated the same as a standard model.

If a model is an AllOf or does not have any composed schemas at all, the sub-models are in-lined defined in the struct. In this case, the standard logic of including the time and os imports apply.

If a model is a OneOf or AnyOf, the sub-models are included as pointers to the defined model. In this case, do not include those items in the logic of including time and os imports.

* Update example to include a time in an allOf

* Add back the accidentally removed nil check

+## Properties
+
+Name | Type | Description | Notes
+------------ | ------------- | ------------- | -------------
+**Test** | Pointer to **time.Time** |  | [optional] 
+
+## Methods
+
+### NewAllOfPrimitiveTypes
+
+`func NewAllOfPrimitiveTypes() *AllOfPrimitiveTypes`
+
+NewAllOfPrimitiveTypes instantiates a new AllOfPrimitiveTypes object
+This constructor will assign default values to properties that have it defined,
+and makes sure properties required by API are set, but the set of arguments
+will change when the set of required properties is changed
+
+### NewAllOfPrimitiveTypesWithDefaults
+
+`func NewAllOfPrimitiveTypesWithDefaults() *AllOfPrimitiveTypes`
+
+NewAllOfPrimitiveTypesWithDefaults instantiates a new AllOfPrimitiveTypes object
+This constructor will only assign default values to properties that have it defined,
+but it doesn't guarantee that properties required by API are set
+
+### GetTest
+
+`func (o *AllOfPrimitiveTypes) GetTest() time.Time`
+
+GetTest returns the Test field if non-nil, zero value otherwise.
+
+### GetTestOk
+
+`func (o *AllOfPrimitiveTypes) GetTestOk() (*time.Time, bool)`
+
+GetTestOk returns a tuple with the Test field if it's non-nil, zero value otherwise
+and a boolean to check if the value has been set.
+
+### SetTest
+
+`func (o *AllOfPrimitiveTypes) SetTest(v time.Time)`
+
+SetTest sets Test field to given value.
+
+### HasTest
+
+`func (o *AllOfPrimitiveTypes) HasTest() bool`
+
+HasTest returns a boolean if a field has been set.

Subject: [PATCH 212/352] [java] Fix template logic related to supportUrlQuery 
 (#14496)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* [java] Fix template logic related to supportUrlQuery

Generated models for arrays marked with uniqueItems: true (which end up as a Set<> in java) won't
compile because the templates are in some places using .get(i) on the sets.

Also, when the supportUrlQuery property is present in the additionalProperties map the
resulting value will be read using the key SUPPORT_STREAMING instead of 'supportUrlQuery'.

* fix NPE

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+# OpenAPI generated API stub
+
+[Spring Framework 6 HTTP Interface](https://docs.spring.io/spring-framework/docs/6.0.0/reference/html/integration.html#rest-http-interface)
+
+
+## Overview
+This code was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.
+By using the [OpenAPI-Spec](https://openapis.org), you can easily generate an API stub.
+This is an example of building API stub interfaces in Java using the Spring framework.
+
+The stubs generated can be used in your existing Spring application for HTTP integration with other REST services
+To use auto-generated interfaces you have to create your own configuration which extends default abstract configurator & provide `WebClient` instance via constructor
+```java
+@Configuration
+public class MyConfiguration extends org.openapitools.configuration.HttpInterfacesAbstractConfigurator {
+
+    public MyConfiguration(WebClient myWebClient) { // separately created WebClient instance
+        super(myWebClient);
+    }
+}
+```

Subject: [PATCH 226/352] Added a Julia client and server (#14520)

* Added a Julia client and server

This PR adds two new generators for the [Julia language](https://julialang.org/)
- `julia-client` to generate a client from specifications
- `julia-server` to generate a server with stubs that can be used to host a server conforming to the specifications

The generated code uses the Julia [OpenAPI.jl](https://github.com/JuliaComputing/OpenAPI.jl) package that includes support functions for both client and server.

* fix javadoc generation

* add changes after ensure-up-to-date run

+# Julia API client for {{packageName}}
+
+{{#appDescriptionWithNewLines}}
+{{{.}}}
+{{/appDescriptionWithNewLines}}
+
+## Overview
+This API client was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.  By using the [openapi-spec](https://openapis.org) from a remote server, you can easily generate an API client.
+
+- API version: {{appVersion}}
+{{^hideGenerationTimestamp}}
+- Build date: {{generatedDate}}
+{{/hideGenerationTimestamp}}
+- Build package: {{generatorClass}}
+{{#infoUrl}}
+For more information, please visit [{{{infoUrl}}}]({{{infoUrl}}})
+{{/infoUrl}}
+
+
+## Installation
+Place the Julia files generated under the `src` folder in your Julia project. Include {{packageName}}.jl in the project code.
+It would include the module named {{packageName}}.
+
+Documentation is generated as markdown files under the `docs` folder. You can include them in your project documentation.
+Documentation is also embedded in Julia which can be used with a Julia specific documentation generator.

+# Julia API server for {{packageName}}
+
+{{#appDescriptionWithNewLines}}
+{{{.}}}
+{{/appDescriptionWithNewLines}}
+
+## Overview
+This API server was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.  By using the [openapi-spec](https://openapis.org) from a remote server, you can easily generate an API client.
+
+- API version: {{appVersion}}
+{{^hideGenerationTimestamp}}
+- Build date: {{generatedDate}}
+{{/hideGenerationTimestamp}}
+- Build package: {{generatorClass}}
+{{#infoUrl}}
+For more information, please visit [{{{infoUrl}}}]({{{infoUrl}}})
+{{/infoUrl}}
+
+
+## Installation
+Place the Julia files generated under the `src` folder in your Julia project. Include {{packageName}}.jl in the project code.
+It would include the module named {{packageName}}.
+
+Implement the server methods as listed below. They are also documented with the {{packageName}} module.
+Launch a HTTP server with a router that has all handlers registered. A `register` method is provided in {{packageName}} module for convenience.
+
+```julia
+register(
+    router::HTTP.Router,        # Router to register handlers in
+    impl;                       # Module that implements the server methods
+    path_prefix::String="",     # Prefix to be applied to all paths
+    optional_middlewares...     # Optional middlewares to be applied to all handlers
+)
+```
+
+Optional middlewares can be one or more of:
+- `init`: called before the request is processed
+- `pre_validation`: called after the request is parsed but before validation
+- `pre_invoke`: called after validation but before the handler is invoked
+- `post_invoke`: called after the handler is invoked but before the response is sent
+
+The order in which middlewares are invoked are:
+`init |> read |> pre_validation |> validate |> pre_invoke |> invoke |> post_invoke`
+
+
+## API Endpoints
+
+The following server methods must be implemented:
+
+Class | Method | HTTP request | Description
+------------ | ------------- | ------------- | -------------
+{{#apiInfo}}{{#apis}}{{#operations}}{{#operation}}*{{classname}}* | [**{{operationId}}**]({{apiDocPath}}{{classname}}.md#{{operationIdLowerCase}}) | **{{httpMethod}}** {{path}} | {{summary}}
+{{/operation}}{{/operations}}{{/apis}}{{/apiInfo}}
+
+
+## Models
+
+{{#models}}{{#model}} - [{{{classname}}}]({{modelDocPath}}{{{classname}}}.md)
+{{/model}}{{/models}}

+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:

+# Julia API client for PetStoreClient
+
+This is a sample server Petstore server. For this sample, you can use the api key `special-key` to test the authorization filters.
+
+## Overview
+This API client was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.  By using the [openapi-spec](https://openapis.org) from a remote server, you can easily generate an API client.
+
+- API version: 1.0.0
+- Build package: org.openapitools.codegen.languages.JuliaClientCodegen
+
+
+## Installation
+Place the Julia files generated under the `src` folder in your Julia project. Include PetStoreClient.jl in the project code.
+It would include the module named PetStoreClient.
+
+Documentation is generated as markdown files under the `docs` folder. You can include them in your project documentation.
+Documentation is also embedded in Julia which can be used with a Julia specific documentation generator.
+

+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:

+# Julia API server for PetStoreServer
+
+This is a sample server Petstore server. For this sample, you can use the api key `special-key` to test the authorization filters.
+
+## Overview
+This API server was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.  By using the [openapi-spec](https://openapis.org) from a remote server, you can easily generate an API client.
+
+- API version: 1.0.0
+- Build package: org.openapitools.codegen.languages.JuliaServerCodegen
+
+
+## Installation
+Place the Julia files generated under the `src` folder in your Julia project. Include PetStoreServer.jl in the project code.
+It would include the module named PetStoreServer.
+
+Implement the server methods as listed below. They are also documented with the PetStoreServer module.
+Launch a HTTP server with a router that has all handlers registered. A `register` method is provided in PetStoreServer module for convenience.
+
+```julia
+register(
+    router::HTTP.Router,        # Router to register handlers in
+    impl;                       # Module that implements the server methods
+    path_prefix::String="",     # Prefix to be applied to all paths
+    optional_middlewares...     # Optional middlewares to be applied to all handlers
+)
+```
+
+Optional middlewares can be one or more of:
+- `init`: called before the request is processed
+- `pre_validation`: called after the request is parsed but before validation
+- `pre_invoke`: called after validation but before the handler is invoked
+- `post_invoke`: called after the handler is invoked but before the response is sent
+
+The order in which middlewares are invoked are:
+`init |> read |> pre_validation |> validate |> pre_invoke |> invoke |> post_invoke`
+
+
+## API Endpoints

+The following server methods must be implemented:

+## METADATA
+
+| Property | Value | Notes |
+| -------- | ----- | ----- |
+| generator name | jetbrains-http-client | pass this to the generate command after -g |
+| generator stability | EXPERIMENTAL | |
+| generator type | CLIENT | |
+| generator language | Jetbrains HTTP Client (HTTP/REST) | |
+| generator default templating engine | mustache | |
+| helpTxt | Generates a jetbrains-http client. See https://www.jetbrains.com/help/idea/http-client-in-product-code-editor.html | |
+
+## CONFIG OPTIONS
+These options may be applied as additional-properties (cli) or configOptions (plugins). Refer to [configuration docs](https://openapi-generator.tech/docs/configuration) for more details.
+
+| Option | Description | Values | Default |
+| ------ | ----------- | ------ | ------- |
+|allowUnicodeIdentifiers|boolean, toggles whether unicode identifiers are allowed in names or not, default is false| |false|
+|disallowAdditionalPropertiesIfNotPresent|If false, the 'additionalProperties' implementation (set to true by default) is compliant with the OAS and JSON schema specifications. If true (default), keep the old (incorrect) behaviour that 'additionalProperties' is set to false by default.|<dl><dt>**false**</dt><dd>The 'additionalProperties' implementation is compliant with the OAS and JSON schema specifications.</dd><dt>**true**</dt><dd>Keep the old (incorrect) behaviour that 'additionalProperties' is set to false by default.</dd></dl>|true|
+|ensureUniqueParams|Whether to ensure parameter names are unique in an operation (rename parameters that are not).| |true|
+|enumUnknownDefaultCase|If the server adds new enum cases, that are unknown by an old spec/client, the client will fail to parse the network response.With this option enabled, each enum will have a new case, 'unknown_default_open_api', so that when the server sends an enum case that is not known by the client/spec, they can safely fallback to this case.|<dl><dt>**false**</dt><dd>No changes to the enum's are made, this is the default option.</dd><dt>**true**</dt><dd>With this option enabled, each enum will have a new case, 'unknown_default_open_api', so that when the enum case sent by the server is not known by the client/spec, can safely be decoded to this case.</dd></dl>|false|
+|legacyDiscriminatorBehavior|Set to false for generators with better support for discriminators. (Python, Java, Go, PowerShell, C#have this enabled by default).|<dl><dt>**true**</dt><dd>The mapping in the discriminator includes descendent schemas that allOf inherit from self and the discriminator mapping schemas in the OAS document.</dd><dt>**false**</dt><dd>The mapping in the discriminator includes any descendent schemas that allOf inherit from self, any oneOf schemas, any anyOf schemas, any x-discriminator-values, and the discriminator mapping schemas in the OAS document AND Codegen validates that oneOf and anyOf schemas contain the required discriminator and throws an error if the discriminator is missing.</dd></dl>|true|
+|prependFormOrBodyParameters|Add form or body parameters to the beginning of the parameter list.| |false|
+|sortModelPropertiesByRequiredFlag|Sort model properties to place required parameters before optional parameters.| |true|
+|sortParamsByRequiredFlag|Sort method arguments to place required parameters before optional parameters.| |true|

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+# openAPIPetstore
+
+This Kotlin based [Spring Boot](https://spring.io/projects/spring-boot) application has been generated using the [OpenAPI Generator](https://github.com/OpenAPITools/openapi-generator).
+
+## Getting Started
+
+This document assumes you have either maven or gradle available, either via the wrapper or otherwise. This does not come with a gradle / maven wrapper checked in.
+
+By default a [`pom.xml`](pom.xml) file will be generated. If you specified `gradleBuildFile=true` when generating this project, a `build.gradle.kts` will also be generated. Note this uses [Gradle Kotlin DSL](https://github.com/gradle/kotlin-dsl).
+
+To build the project using maven, run:
+```bash
+mvn package && java -jar target/openapi-spring-1.0.0.jar
+```
+

 The difference here is that you may define `generateModels` and `modelsToGenerate` as properties, while `globalProperties` may only be configured as a configuration node.
 
+### Type and import mappings
+
+To override the mappings between OpenAPI spec types and the types used in the generated code, set `typeMappings`.
+
+```xml
+<configuration>
+    <typeMappings>
+        <!-- convert Double to BigDecimal -->
+        <typeMapping>Double=java.math.BigDecimal</typeMapping>
+    </typeMappings>
+</configuration>
+```
+
+For types that are not already included in the generator configuration, you may need to add a corresponding `importMapping` too.
+
+```xml
+<configuration>
+    <!-- convert file/binary to JAX-RS StreamingOutput -->
+    <typeMappings>
+        <typeMapping>binary=StreamingOutput</typeMapping>
+        <typeMapping>file=StreamingOutput</typeMapping>
+    </typeMappings>
+    <importMappings>
+        <importMapping>StreamingOutput=javax.ws.rs.core.StreamingOutput</importMapping>
+    </importMappings>
+</configuration>
+```
+
+
 ### Custom Generator
 
 Specifying a custom generator is a bit different. It doesn't support the classpath:/ syntax, but it does support the fully qualified name of the package. You can also specify your custom templates, which also get pulled in. Notice the dependency on a project, in the plugin scope. That would be your generator/template jar.

This is the original openapi-generator behavior.This setting is currently ignored for OAS 2.0 documents:  1) When the 'additionalProperties' keyword is not present in a 2.0 schema, additional properties are NOT allowed.  2) Boolean values of the 'additionalProperties' keyword are ignored.

-      If a schema in the OpenAPI document defines the additionalProperties attribute,

Subject: [PATCH 256/352] [java][jersey] Fix ALLOW_COERCION_OF_SCALARS (#14619)

* Remove dead code

* Refactor containsKey before get

* Minor refactor

* Use JsonMapper.builder() to build ObjectMapper

Fix a bug where ALLOW_COERCION_OF_SCALARS wasn't set properly.

* Update samples

* Oops, fix a typo

Subject: [PATCH 263/352] [Kotlin-Spring] Support multiline descriptions
 (#14406)

* [Kotlin-Spring] Support multiline descriptions

This commit adds support for multiline descriptions for operations in
the Kotlin-Spring generator, for both regular API generation (i.e.
Controller), as well as interface-only API generation.

Multiline descriptions allow us to use rich text representations, e.g.
with Markdown. Note that Markdown-formatted descriptions are rendered
nicely in Swagger-UI. I imagine that most openapi consumers will be able
(or will want to) support Markdown (at some point).

The solution for Kotlin-Spring is rather simple, using Raw Strings to
contain the `unescapedNotes`.

See: https://kotlinlang.org/docs/strings.html#raw-strings

Note that specific unescaped strings could cause problems. For example,
the string containing three double quotes `"""` would result in compile
errors for the generated code. I think this is acceptable.

Note that an improvement is possible to use `.trimMargin()` in
combination with the pipe symbol `|`, to allow specific margin
prefixing.

Note that the description is used in escaped form in the JavaDoc. This
could be resolved by prefixing every line of the unescapedNotes with a
star `*`.

For now, I've chosen to implement this the simplest way I could think
off.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

 ## Overview
 OpenAPI Generator allows generation of API client libraries (SDK generation), server stubs,  documentation and configuration automatically given an [OpenAPI Spec](https://github.com/OAI/OpenAPI-Specification) (both 2.0 and 3.0 are supported). Currently, the following languages/frameworks are supported:

+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+# JAX-RS server with OpenAPI
+
+## Overview
+This server was generated by the [OpenAPI Generator](https://openapi-generator.tech) project. By using an
+[OpenAPI-Spec](https://openapis.org), you can easily generate a server stub.
+
+This is an example of building a OpenAPI-enabled JAX-RS server.
+This example uses the [JAX-RS](https://jax-rs-spec.java.net/) framework.
+
+
+The JAX-RS implementation needs to be provided by the application server you are deploying on.
+
+To run the server from the command line, you can use maven to provision and start a TomEE Server.
+Please execute the following:
+
+```
+mvn -Dtomee-embedded-plugin.http=80 package org.apache.tomee.maven:tomee-embedded-maven-plugin:7.0.5:run
+```
+
+You can then call your server endpoints under:
+
+```
+http://localhost:80/v2/
+```
+
+Note that if you have configured the `host` to be something other than localhost, the calls through
+swagger-ui will be directed to that host and not localhost!

Subject: [PATCH 324/352] Stop using org.springframework.util.Base64Utils in
 Java generators (#14813)

This utility class has been marked as deprecated for future removal since Spring 6.0.5. All Java generators, except WebClient and RestTemplate, are already using Base64 directly.
