[BUG] Model Name Mapping is not functional in Java codegen.

Bug Report Checklist

Hi, I have attempted to use the modelNameMapping configuration. But the generated SDK does not seem to render it.

Went through few reference PRs. #16209

The configuration was passed via pom.xml

Seems like the support is available only for select generators.

Could you please suggest how to proceed and enable support for java.

• Have you provided a full/minimal spec to reproduce the issue?

which openapi generator are you using? can you share the full pom.xml to repeat the issue more easily?

@wing328 Sure, have updated the entire plugin. Please do note that the same thing didn't work even with plugin version 7.1.0. As a workaround what I have done is create a class and use it via schemaMapping.

My usecase is that if I have List<EntityModel<UserAccount>> to enable Spring Hateoas links, The generated class name is EntityModelUserAccount instead of UserAccount causing the SDK consumers to break. Hence, trying to make sure that the generated SDK will continue with the same name.

I have the same problem. The --model-name-mappings option seems to have no effect for -g java --library okhttp-gson.
