问题
I have a question about updating GitHub plugin.
Everytime I do an update plugin such as GitHub and restart the jenkins, Jenkins start crashing. when I try to access jenkins through URL in my browser, the error page shows up with some exception "class not found jenkins/model jenkins" . and then in order to make jenkins working again , I have to delete the plugin entirely from the plugins directory. I wish someone has an answer for this because I really need to make my github projects available to jenkins for build. Thanks

It is a very usual problem with Jenkins. My workaround was to either update the jenkins (where ever it is installed) and restarting the hudson service. sometimes even restarting the service works. often you might need to remove those plugins from within (/var/lib/hudson/plugins/) and restart the service.
