JBTIS-27 asks that the core and JBTIS integration tests (itests) be split into a new repo.
However, some of those itests depend on upstream tests unit tests (utests)... ESB, for example.
So, either you
- need to publish a site from which these can be resolved 
- :: more jobs to maintain, but will make downstream builds resolve p2 deps faster, and facilitate doing headless automated test plugin installation w/ install-grinder or p2.director
- or you need to ensure that when building/running the itests, you point at the composite JBTIS site .
- :: requires that you produce a folder somewhere on download.jboss.org, like this one , and maintain that composite site... since you can't link to a folder on raw.github.com 
 https://raw.github.com/jbosstools/jbosstools-integration-stack/master/jbosstools/site/ is 404'd
Both options would work... but I suggest that building a new aggregate might be better.
If you agree, you'll want to therefore migrate the code in
to a folder under
