I'm trying to manually downgrade Mailer to 1.11 from 1.15, but every time I do, it seems hell-bent on re-appearing as 1.15. Since there's no nice uninstall button for it in Jenkins, I'm removing the JPI and related folder from $JENKINS_HOME/plugins then restarting the Jenkins service per the Jenkin

You're likely using a plugin that requires a newer version of Jenkins than 1.532.x (specifically 1.577 or newer). Possibly because you manage those using Chef or a similar tool and completely ignore the plugins' dependencies. On 07.04.2015, at 12:56, Andrew Langhorn wrote: > Hi, > > We run J
