    [ https://issues.jboss.org/browse/JBIDE-16220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12938162#comment-12938162 ] 

Mickael Istria commented on JBIDE-16220:
----------------------------------------

> btw. unit tests cannot catch api issues if they are constantly built against the latest and just updated to work.

They don't catch up API versioning issues, but they do catch up breaking changes. ie if API change in a non-backward compatible way, we can expect a test to fail with a NoSuchMethodError or a NoClassDefFound.

> Git 1.8.2 includes an option to have submodules track a branch tip, rather than specific commit IDs.
> {code:title=https://github.com/git/git/blob/master/Documentation/RelNotes/1.8.2.txt#L186-L188}
>  "git submodule" started learning a new mode to integrate with the
>    tip of the remote branch (as opposed to integrating with the commit
>    recorded in the superproject's gitlink).
> {code}
> Therefore, while the solution [~dgolovin] has for his https://github.com/dgolovin/jbosstools-submodules project is a decent option, it requires updating to stay current with branch tips. It's therefore only really as useful as it stays current.
> If we can get Git 1.8.2 or newer installed on the Jenkins slaves, we could do a submodule build against whatever branch we wanted - master, 4.2.0.Alpha1x, etc.
