The <executePhase> part looks incorrect to me, and might explain the
problem as it would essentially setup an infinite loop in the
lifecycle and might explain why the plugin version isn't discovered.
Regardless, this would be a bug that it is not reported as an error properly.
I'm not sure why it is there, given you don't list it in your javadoc.
Can you confirm that it really is the same?
Thanks,
Brett
