java - Swagger Codegen生成重复的变量

我正在尝试从包含以下内容的Yaml生成客户端

  acceptParam:
    name: Accept
    type: string
    required: true
    in: header
    description: Accepted Content-type. Should be set to application/json
  contentTypeParam:
    name: Content-Type
    type: string
    required: true
    in: header
    description: Request Content-type. Should be set to application/json

这意味着accept并且contentType将出现在生成的方法签名中。

最重要的是，我像这样配置插件

<plugin>
    <groupId>io.swagger.codegen.v3</groupId>
    <artifactId>swagger-codegen-maven-plugin</artifactId>
    <version>3.0.18</version>
    <executions>
        <execution>
            <goals>
                <goal>generate</goal>
            </goals>
            <phase>generate-sources</phase>
            <configuration>
                <inputSpec>${project.basedir}/src/main/resources/swagger.yaml</inputSpec>
                <language>java</language>
                <configOptions>
                    <dateLibrary>joda</dateLibrary>
                    <localVarPrefix>localVar</localVarPrefix>
                </configOptions>
                <library>resttemplate</library>
                <output>${project.build.directory}/generated-sources</output>
                <modelPackage>com.example.client.model</modelPackage>
                <apiPackage>com.example.client.api</apiPackage>
                <generateApiTests>false</generateApiTests>
                <generateModelTests>false</generateModelTests>
            </configuration>
        </execution>
    </executions>
</plugin>

不过，之后 mvn clean install

我越来越

错误：（130,31）Java：方法中已经定义了变量accept

并且生成的代码包含

public Response authorize(Request body, String accept, ...) {
   ....
   final List<MediaType> accept = apiClient.selectHeaderAccept(accepts);    
   ....
}

我尝试了不同版本的插件（从2.3.0到最新版本），在克服了许多其他问题之后，我总是这样结束。
