Thanks Kenney, that fixed the problem. At the same time, it would be
helpful if the error explained this nuance.
Before I add to Jira, can we assume that MavenProject.getArtifacts()
should *never* return null for a valid project with resolved
dependencies? If so, the method could throw an
DependencyResolutionRequiredException instead:
"Dependencies have not been resolved. If this is a plugin, verify that
@requiresDependencyResolution is set in the mojo object. See the
developer's documentation for more detail."
Thoughts?
