[JAVA] there is no way to deal with duplicated names

Description

I have a swaggery.json that contains duplicated variable name as path and query parameters. swagger-codegen doesn't provide an option to deal with such collisions.

There is no way to update swagger.json because it's coming from external resource provided by 3rd party.

Maybe, there is some workaround?

Swagger-codegen version

3.0.24

Command line used for generation

swaggerSources {
    retrofit2 {
        inputFile = file("${projectDir}/../schemas/swagger.json")
        code {
            language = 'java'
            library = 'retrofit2'
            additionalProperties = [
                    modelPackage           : "retrofit2.model",
                    apiPackage             : "retrofit2",
                    dateLibrary: 'java8',
                    interfacesOnly: 'true'
            ]
        }
    }
}

Start by reproducing generation with the provided swagger.json and the Gradle swaggerSources configuration for the Java retrofit2 library. Trace how the path and query parameters named itemId are handled, then define and verify an option for resolving that collision without changing the external specification.
