Question: type-mapping generation for import-mappings

Description

I am wondering if there is any way to generate a file containing the type-mappings that were generated so that they could be passed into another api gen the is utilizing data models from the first.

I have been creating multiple oas definitions with empty paths and defined components, and then using Maven to version and manage these definitions as dependencies in other projects with oas definitions. The intended result is a collection of API definitions for different services within a specific business domain that can all share a set of common data models.

Ideally, I would only want to generate each common data model once. I believe the way to do this would be to create an import-mappings string that would map all my previously generated data model names to their corresponding class names.

But this would be tedious and error prone to maintain by hand. Is there a way to generate a file that contains these mappings that I could then pass in as an import-mappings file?

openapi-generator version

openapi-generator-maven-plugin:3.0.0

using java generator name

The issue names the Java generator and openapi-generator-maven-plugin; start by examining how generated type mappings and the import-mappings option are handled. Define whether an emitted mappings file can be consumed by another generation run, and verify the behavior with shared models across multiple OpenAPI definitions.
