Howdy, my pain point was plugin-testing-harness 3.3.0 that is really ancient, while master of it was mixing maven3 and maven4 support... so I went to split things.
IMO we need to split (like maven-3.x and master branch) for maven 3 and maven 4 support, as there is really no need to support "both", as in case of plugins, they are "this or that", they cannot be maven3 and maven4 at the same time. Hence, I started with maven-plugin-testing: https://github.com/apache/maven-plugin-testing/tree/maven-3.x Please eyeball and would like to prepare a 3.4.0 release of it soon. By the way, same should be done in maven-plugin-plugin (no need to support creation of maven3 and maven4 plugins at the same time)... and maybe same pattern (using branches maven-3.x and master for 3 and 4) should be applied to all plugins? Thanks T
