Subject RE: eclipse and maven working together...
Date Thu, 14 Mar 2013 03:48:46 GMT
Oh and btw, I checked in a new profile called impatient.  With it, I cut off a whole minute
(about 25% for me) off the build.  Use it in place of developer.  Developer profile is still
there.

mvn -o -P impatient,systemvm clean install -DskipTests=true
