Brett Porter closed MNG-4858.
-----------------------------
Resolution: Fixed
Fix Version/s: 3.0.1
Fixed in r1005860. After discussing with Benjamin, decided not to go for an
IllegalArgumentException as it would not represent a clear error link to the
user receiving it. Instead, the empty goal or overspecified goal (goal:toomany)
are sent to the MojoNotFoundException so the user ends up getting back valid
choices of goals from the plugin in question.
> NullPointerException if goal name is malformed
