Jason van Zyl commented on MNG-3960:
------------------------------------
This is result of cleaning out some code in Plexus, no one has ever implemented
the Suspendable interface but it won't hurt to restore them and then this
problem will go away.
> cannot build projects which use plexus-maven-plugin with 3.0-alpha-1
