It would be great if local build of windup eclipse plugins could create a composite update site.

Details:

1) windup eclipse plugin source: https://github.com/windup/windup-eclipse-plugin

2) windup eclipse code nightly update site: http://download.jboss.org/jbosstools/neon/snapshots/builds/windup-eclipse-plugin-NIGHTLY/latest/all/repo/

3) jbt dependency update site: http://download.jboss.org/jbosstools/neon/snapshots/updates/

4) Jenkins job: https://jenkins.mw.lab.eng.bos.redhat.com/hudson/view/Windup/job/windup-eclipse-plugin-NIGHTLY/

Making these maven flags would allow for easier over-riding so that when windup tools branch for alpha1 they can change the deps to our am2 release for stability.
