Author: stephenc

New Revision: 1143035

URL: http://svn.apache.org/viewvc?rev=1143035&view=rev
Log:
[MDEP-316] dependency:copy and dependency:unpack behave differently with M2 and M3 (should always search the reactor for artifacts)

o With this patch all copy and unpack will not resolve from the reactor always (both M2 and M3)
