> When creating a feature pack, a missing dependency caused the AetherArtifactFile resolver to throw an NPE.  However, it did not give any clue as to which dependency was missing.  I will submit a patch for this so that a proper error message can accompany a RuntimeException.
> Here is the stack trace for the NPE:
