that's what we're already doing (well technicall yin the `pre-package`
phase).
Thing is that the `package` phase is _always_ executed before `verify`, and
we can't get around that aside from building a custom life-cycle. And we have
to print a warning in this case, as the jar is still created and thus could be
used.---
