First, you can open a bug in JIRA, since a NPE like this should at least be
avoid to throw a more user friendly exception. To help find the origin of
the NPE, please run your build in verbose mode to get the full stack trace.

Second, I see many "null" in your logs, maybe you have a resolver with no
name? This should raise a clear error, but maybe we have a bug there.
