How do I configure Jenkins to strip the leading “origin/” in git branch parameter?
I'm using Jenkins with a branch parameter to specify the branch to build from. Other stuff downstream needs the branch name to not have the leading "origin/" -- just "feature/blahblah" or "bugfix/12345" or similar. The advanced settings for the parameter let me specify a branch filter via regex, but I'm a regex newbie and the solutions I've found in searching are language-dependent. The Jenkins documentation for this is sparse.
When a user clicks on "build with parameters", for the branch I want to see branch names that omit the leading "origin/". I'm not sure how to write a regex for Jenkins that will "consume" that part of the branch name before setting the parameter value.
