|enumPropertyNaming|Naming convention for enum properties: 'camelCase', 'PascalCase', 'snake_case', 'UPPERCASE', and 'original'| |camelCase|

|interfaceOnly|Whether to generate only API interface stubs without the server files.| |false|

|sortModelPropertiesByRequiredFlag|Sort model properties to place required parameters before optional parameters.| |null|
|sortParamsByRequiredFlag|Sort method arguments to place required parameters before optional parameters.| |null|
|sourceFolder|source folder for generated code| |src/main/kotlin|
