What I want to do is to give jenkins two git repos (local, remote)
and make him build every commit in any branch from local, for each of them merge with the same branch from remote.

so my branch spec is local/**

and before build I want to merge with remote with the same branch. local is a clone of remote, and they get synchronized often.

Where i failed is that i specified in "Branch to merge to" value ${GIT_BRANCH}, but this didn't get resolved, and i saw
