First the approach to modularization should be thought out, as jlink/jpackage is picky about only packaging modules. Now our packages are not modularized, and modularization and unit tests somewhat conflict with each other. Unit tests normally in the same package as the tested unit, but modularization does not allow you to have multiple source trees (main and test) exporting the same package. There are workarounds which might be effectively handled by the build framework provided by konveyor, but these need to be explored and tested.

There is a PoC for packaging in the magwas/testfx repo, including the pom and github actions, packaging to linux and windows, and also able to create web server package delivering the UI.
