How to resolve 'Failed Loading item <job name>' ?

[David Aldrich]

Hi

 

I have deleted some jobs that used the deprecated multi-branch project plugin. I have also uninstalled that plugin. 

 

Since restarting the system (running Jenkins 2.85) I get exceptions for those deleted jobs:

 

Failed Loading item <job name>

com.thoughtworks.xstream.mapper.CannotResolveClassException: freestyle-multi-branch-project

 

How can I clear these?

 

(The entire exception is shown below).

 

Best regards

 

David

Two options:
1. Install the plugin again, delete the jobs from the UI
2. Delete the folders on disk

I did delete the jobs from the UI before removing the plugin. So I guess I need to delete them from disk. Would that be from the master at:

/var/lib/jenkins/jobs

?
