+# 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-jersey2-java8-localdatetime</artifactId>
+  <version>1.0.0</version>
+  <scope>compile</scope>
+</dependency>
+```
+
+### Gradle users
+
+Add this dependency to your project's build file:
+
+```groovy
+compile "org.openapitools:petstore-jersey2-java8-localdatetime:1.0.0"
+```
+
+### Others
+
+At first generate the JAR by executing:
+
+```shell
+mvn clean package
+```
+
+Then manually install the following JARs:
+
+- `target/petstore-jersey2-java8-localdatetime-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.AnotherFakeApi;
+
+...
+
+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);
+
+AnotherFakeApi apiInstance = new AnotherFakeApi(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.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 body = new Client(); // Client | client model
+        try {
+            Client result = apiInstance.call123testSpecialTags(body);
+            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();
+        }
+    }
+}
+
+```
