Jobs are stuck after a restart

[heurtematte]

This is a recurring issue where the jenkins build queue is stuck after a reboot.

Workaround: clear the queue with Jenkins.instance.queue.clear()

Doing exactly what @heurtematte mentioned 😄 https://github.com/jenkinsci/purge-build-queue-plugin/blob/master/src/main/java/io/jenkins/plugins/PurgeBuildQueueAction.java#L74

Yep, but we would still need to do it manually. Would be nice to allow this action only for project leads.

@mbarbero wdyt about a groovy init script that clears the queue after every Jenkins start?

agreed.

it depends :) Do we have cases where a Jenkins restart actually leads to successful jobs restart? If that's the case, then it means that by implementing your plan, you will effectively solve your issue, but also remove the auto-restart feature for others.

I don't have hard numbers, but anecdotally it's rare that jobs in the queue start cleanly after a restart.

+1 groovy init script

If it don't work as expected, install `purge-build-queue-plugin for project.

On https://ci.eclipse.org/sirius, I observed that some jobs have dissapered (without any information, as if they never existed). For example, a job sirius.sonar-master has been launched this morning. But it never ended and it is no longer visible. Is there a link with this issue ?

Please open a separate HelpDesk issue about this.
