Is your feature request related to a problem? Please describe.

Maven uses two different folders generated-sources and generated-test-sources. Test related files supose to get into generated-test-source folder. In current implementation all generated files in a single forlder - ${project.build.directory}/generated-sources/openapi by default.

there are problems with the approach:

• test files go to production artifact
• production artifact becomes dependencies (it increses dangerous in the light of recent vulnerability in logging library - the more non essential libraries in prod the likely to catch new vulnerability)

I suspect that majority of java developers just disable generating the test files

I wonder if it it possible to make mvn plugin alligned with conventional folder-structure

Describe the solution you'd like

The solution is to introduce additional parameter testOutput which is ${project.build.directory}/generated-test-sources/openapi by default.

Describe alternatives you've considered

there are several workarounds:

• copy test files after generation with another maven plugin
• use org.codehouse.mojo:build-helper-maven-plugin to mark the folder with test files as mvn-test-source

both of these ways have different flaws
