Java code generation fails with id & setId field names

[dhoffer]

Description

I have a Java model class that has these fields (and more).

private String id;
private String setId;

openapi-generator version

7.10.0

OpenAPI declaration file content or url

type: object
      properties:
        id:
          description: "Unique identifier of the record."
          maxLength: 36
          minLength: 1
          type: string
          example: 3b0b1b1a-a3c0-4267-894a-0c40cb84a5af
        setId:
          description: User-defined ID.
          type: string
          example: 2b0b1b1a-a3c0-4267-894a-0c40cb84a5af

Generation Details

Steps to reproduce

The issue is that the codegen tool has correctly made the setId() method for the id field but then it makes another setId() method for the setId field which is incorrect. It should be making a setSetId() method for the setId field.

How to fix/resolve this?

please give it a try with the name mapping option: https://github.com/openapitools/openapi-generator/blob/master/docs/customization.md#name-mapping

I am using the Maven plugin and could not determine how to use the name mapper with the plugin, How would I add that to the configOptions?

      <cleanupOutput>true</cleanupOutput>
      <skipValidateSpec>false</skipValidateSpec>
      <useJakartaEe>true</useJakartaEe>
      <dateLibrary>java8</dateLibrary>
      <library>apache-httpclient</library>
      <identifierNamingConvention>snake_case</identifierNamingConvention>

Here is an example of what I tried and it didn't work.

            <cleanupOutput>true</cleanupOutput>
            <nameMappings>setId=similarSetId</nameMappings>

I just figured out how to do this, it must be set in the configuration element group and then set like this:

<nameMappings> <nameMapping>setId=userDefinedId</nameMapping> </nameMappings>
