我有下面打开的API模式文件

openapi: 3.0.1
info:
  title: tt
  version: 1.0.0
servers:
  - url: https://1.1.1.1
paths:
  /controller/user/login:
    post:
      tags:
        - default
      summary: Login
      requestBody:
        content:
          application/json:
            schema:
              type: object
              example:
                email: user
                password: user
                from: user
      parameters:
        - name: Content-Type
          in: header
          schema:
            type: string
          example: application/json
      responses:
        '200':
          description: Successful response
          content:
            application/json: {}

我试图生成java客户端使用下面的pom配置

<plugin>
    <groupId>org.openapitools</groupId>

当我试图生成客户端使用mvn清洁安装我得到下面的错误

DefaultApi.java:[91,25] variable contentType is already defined in method controllerUserLoginPostWithHttpInfo(java.
lang.String,java.lang.Object)

在www.example.com中DefaultApi.java，我看到生成的类包含两个同名的变量

public ResponseEntity<Void> controllerUserLoginPostWithHttpInfo(String contentType, Object body) throws RestClientException {
        Object postBody = body;
        
        String path = apiClient.expandPath("/controller/user/login", Collections.<String, Object>emptyMap());

        final MultiValueMap<String, String> queryParams = new LinkedMultiValueMap<String, String>();
        final HttpHeaders headerParams = new HttpHeaders();
        final MultiValueMap<String, String> cookieParams = new LinkedMultiValueMap<String, String>();
        final MultiValueMap formParams = new LinkedMultiValueMap();

        if (contentType != null)
        headerParams.add("Content-Type", apiClient.parameterToString(contentType));

        final String[] accepts = { 
            "application/json"
        };
        final List<MediaType> accept = apiClient.selectHeaderAccept(accepts);
        final String[] contentTypes = { 
            "application/json"
        };
        final MediaType **contentType** = apiClient.selectHeaderContentType(contentTypes);

        String[] authNames = new String[] {  };

        ParameterizedTypeReference<Void> returnType = new ParameterizedTypeReference<Void>() {};
        return apiClient.invokeAPI(path, HttpMethod.POST, queryParams, postBody, headerParams, cookieParams, formParams, accept, contentType, authNames, returnType);
    }

我也尝试了配置选项，但它不做任何更改

<configOptions>
    ...
    <localVarPrefix>localVar</localVarPrefix>
</configOptions>
