I am using Tycho for my Eclipse OSGi projects, and noticed that for project in Git the Eclipse-SourceReferences header doesn't include the branch. I assume it's because I'm not understanding something about Git as to why the branch isn't necessary. But using just the repo URI, the repo path, and the commit Id, how am I assured I also have checked out the correct branch? If that sounds like a silly question .. a branch is a pointer to the tip commit. So what if the commit Id in the SourceReferences header is the tip of multiple branches?

The Eclipse-SourceReferences header is for pointing at the exact sources used to compile that version of the plug-in. It has never held any greater meaning about the original SCM, such as which branch that commit (or CVS tag) came from.

  • Right, so if I'm trying to get a copy of the source for a plugin in my Target Platform, using the SourceReferences header, don't I need to know the branch to check out after I've cloned? If the commit isn't on master will 'git checkout _commit_' know what branch to checkout? Even if there's more than one branch pointer for it? – Baron Von J Jun 27 '14 at 16:30
