Maven Spring Generator split API/Model/... into different modules

Description

If not already possible, I'd like to propose a new feature to split the API/Model/... not just into different packages but also different modules.

Our current project which we created manually looks like this:

• Project (Parent with packaging pom)
  • App (Module with packaging jar) contains the Application and the Controller Class. Injecting Services which implement the ServiceApi.
  • Model (Module with packaging jar) contains the Models.
  • ServiceApi (Module with packaging jar) contains the Interfaces for the Services by using the Model classes.
  • Services (Module(s) with packaging jar) one for each Impl of the ServiceApi we can inject into the App.

When we could at least use your generator to create the Project, App module and Model module, that would be great :)

openapi-generator version

We are currently using

• groupId: org.openapitools
• artifactId: openapi-generator-maven-plugin
• version: 5.4.0

but are open to use any other version.

OpenAPI declaration file content or url

Following the OpenApi3 Spec

Suggest a fix/enhancement

Additional configuration params or additionalProperties for the plugin in the pom.xml like

• apiModule
• modelModule
• ...

Thanks, kopi

Start by locating the Maven Spring generator and reviewing how its current API and model packages are configured. Compare the requested App, Model, ServiceApi, and Services module layout with the generator's existing options and the suggested apiModule and modelModule parameters. Done means the generator can produce the requested module separation through documented configuration.
