Most likely if you review the system log you'll see that your jobs could not be loaded because one or more plugins are required and they are not present; as another poster said, you'll need to go into the Update Center in the new Jenkins version and fully upgrade all of your plugins. Doing so will probably resolve your problem.
----- Original Message ----- From: jenkinsci-users@googlegroups.com To: jenkinsci-users@googlegroups.com At: Jul 23 2013 08:44:45 Hi, I upgraded Jenkins from 1.466.12 to 1.509.2. After restarting the Jenkins Tomcat server, almost all of the Jobs disappeared from the Jenkins web interface. The file system still showed that all of the jobs; however, they disappeared from the UI. After I restored 1.466.12, the jobs appeared in the Jenkins Web interface. We are using Jenkins Enterprise from CloudBees. Has anyone else seen that behavior (i.e. Jobs missing after doing an upgrade)? If so, any ideas on how to resolve this?
