kredens added a comment - 2023-05-15 06:39 - edited Second time in recent weeks this plugin gets update that breaks the jobs completely  (previous one cleared all the labels set in preferences, but that was at least easy to fix by recreating them). Do you guys even check if it's working before pushing updates?  This is CRITICAL error and this update should either be pulled or fixed - yet, a week later nothing happened.

Christoph Fetzer added a comment - 2023-05-16 07:14 Seems to be a duplicate of JENKINS-71270 . The workaround mentioned there fixed the issue for me. Workaround: Push 'Save' in the Jenkins configuration.

kredens added a comment - 2023-05-16 09:32 - edited Didn't work for me, first thing I did was to try changing some resources definitions (and then saving configuration). 

Donato added a comment - 2023-05-18 03:43 Opening system configuration in "Dashboard > Manage Jenkins > System" and then hitting the 'Save' button WITHOUT any changes worked for me.

Konrad Grochowski added a comment - 2023-06-19 11:04 still reproducible in 1167.v04861534072b_  

Konrad Grochowski added a comment - 2023-06-19 11:18 but now the "workaround" works...
