Hello Martin, Indeed, most of the tests check for regressions and use Maven3-based projects. Quickly glancing through tests, we have some Maven4 (and model 4.1.0) specific: CI-friendly versions, the new "sources" layout structure, and root POMs, to name a few. But you are correct. We do not have explicit tests for modular-jar and classpath-jar dependencies. I will look into that.
