That sounds like a great plan. Doing it in phases allows us to give you feedback early which is also good. Did you see the (partial) list of Maven plugins...

Looks good. Please proceed with phase 2. We should probably add a GitHub `maven.yaml` workflow so we can start testing the Maven build. Do you feel comfortable doing that as...
