I've updated jenkins and all plugins and now git can't poll my git branches anymore.

Found 67 remote heads on git@server:stuff.git
Done. Took 1.4 sec
No changes

But running manually the ls-remote, not only there is no branch at all matching that hash, but the branch in question has clearly a different hash. I've seen other bugs complaining about the plugin picking the first or the last item, or picking from the right side, or doing whatever else incorrectly, but in this case it simply doesn't work at all

git ls-remote -h git@server:stuff.git | grep a1903aa4a6afd4dda0b7c136b21c7f374d9160f2
(nothing)

git ls-remote -h git@server:stuff.git | grep a1903aa4a6afd4dda0b7c136b21c7f374d9160f2 | grep project
