How to retrieve the git branch name that was built by Jenkins when using inverse branch selection strategy?
Looks like it's a Jenkins bug? You can grab in your build script the name of the checked out branch with this:
git symbolic-ref -q --short HEADActually Jenkins has the working copy in detached HEAD, which is why git branch returns "no branch". See this quite detailed answer for digging into reconciliation with between a detached HEAD and a branch.
Because git never checks out a branch just a commit directly you have to do the following:
To get the sha of the checked out commit:
git rev-parse HEADTo get the all branches that commit is under:
git branch -a --contains SHAThe out put of the second command could look like this
masterremotes/origin/HEAD -> origin/masterremotes/origin/develop
