Created a pull request for making "maven-plugin-testing" buildable with
Maven 4.0.0-beta4:
https://github.com/apache/maven-plugin-testing/pull/44
A similar pull request is needed for "maven-compiler-plugin". We could
update the current plugin, or merge the reworked plugin (after
correction of integration tests). The latter would be more disruptive,
with risks of regressions that I didn't spotted with the tests. Is there
any advice about which approach to choose?
With the second option, we would need a page describing the changes in
Maven 4. Even with the first option, we need to document at least the
"<modules>" change. Do we have this page somewhere?
