Exact same problem here.
I tried many ways: clearing jenkins “caches” dir, upgrade all plugins… the problem was still there.
Another workaround I found was to temporarily set git checkouts to use ssh with no credential at all (so using user operating system git).
In fact as soon as I set a credential to git checkout (via https or even uselessly ssh ) I had this problem. I tried also with a brand new credential. Same result.
The only definitive way to fix the problem is to downgrade to jenkins 2.291
This is a very blocking issue I think and should have a higher priority.
Т.е. версия 2.292 не рабочая версия, так что лучше до неё не обновляться. Последняя стабильная версия 2.291
