... simply means "the IUs we're looking for cannot be found on the site(s) listed in the target file (or p2.mirror script generated from the target file).

I was getting the same error when I was validating unified.target BEFORE having publishing the JBT JunoSR0a target platform site. Having pushed the site to the URL specified in unified.target...

the error is still there. Which means we have at least one missing IU on the target platform. Another case of where we require multiple versions of an IU -- in this case, Mylyn needs lucene.core 2.9.1, and checkstyle needs 3.5.

> In order to make maintainance easier and target-platform more reliable, we should improve the way we create target-platforms so we only maintain multople.target and other platforms (local, unified) get generated from it.
