Subject: [PATCH] Adds a test case that exercises the multiple-repository
 -SNAPSHOT issue. #1514

* Create a project "common" which publishes a "bad" artifact.
* Resolve project "dependent" which resolves the "bad" artifact into the cache.
* Publish a new "common" snapshot to a diffferent repository (publishLocal)
* Attempt to build the new project, leading to issues.
