copy of Jenkins system not working

[Nordin, Lars P]

I’m trying to duplicate a current Jenkins setup but I’ve run into problems trying to get the copy working correctly.

Only the deploy jobs are displayed in the UIT and the logs show many of the other jobs fail on job load.

The version of Jenkins is the same and the versions of Java are close (1.7.0_65 vs 1.7.0_71).

I created a copy  by installing Jenkins from rpm, and then copying /var/lib/Jenkins execluding the lower sub-directories in Jenkins/jobs to save space.

 

What do I need to change to fix this?

Lars,

Check to make sure you have the same plugins installed/active on the target system as you do on the source configuration (also make sure the versions of the plugins are the same or at least as close as possible).  Also, check to make sure file owner/permissions are correct on the target system (i.e. match the source system) for the job xml files.

Thanks!  (and thanks for the quick reply!) The git-client plugin was in a funky state. Versions 1.0.5 and 1.6.0 were both installed but on the Jenkins copy the v1.0.5 version was the preferred version instead of v.1.6.0. I fixed the problem by uninstalling git-client plugin and installing just the later version.
