Hi,
I am running Jenkins 2.1 on Mint 17.
I installed the "docker-build-step" plugin (which also installed "docker-common") and noticed upgrades for git and gitlab-plugin so upgrades those too. The latter also upgraded "authentication-tokens" and "credentials".
They installed and I restarted Jenkins. When it restarted there were several problems. When I went to the URL, I got "Please wait while Jenkins is restarting" message. Waited, got bored, restarted server. In /var/logs/jenkins, the log had entry of
Jul 06, 2016 3:44:39 PM hudson.init.impl.InstallUncaughtExceptionHandler$DefaultUncaughtExceptionHandler uncaughtException
SEVERE: A thread (pool-6-thread-2/21) died unexpectedly due to an uncaught exception, this may leave your Jenkins in a bad way and is usually indicative of a bug in the code.
java.lang.NoClassDefFoundError: org/jenkinsci/plugins/github_branch_source/GitHubSCMSource.
So I went to /var/lib/jenkins/plugins and added .disabled to the following jpi files
github-api.jpi
github-branch-source.jpi
github.jpi
github-organization-folder.jpi
Rebooted and url then gave log in screen.
Is there a problem with the github plugins and the upgraded git and gitlab plugins and / or docker plugins?
Regards,
John
