Shutting down my plugin on Jenkins shutdown

[Joachim Nilsson]

Hi

How do I detect Jenkins shut-down in my plug-in so I can close down connections and thread pools in a nice way?

Regards,
Joachim

Hi Joachim,

In general, for that kind of question, the way to go is to search https://wiki.jenkins-ci.org/display/JENKINS/Extension+points for something matching your needs.

Quickly greping myself, though I never did that very thing, maybe implementing either hudson.lifecycle.Lifecycle or hudson.model.RestartListener may be of interest I guess.

My 2 cents

Btw, wondering if Jenkins does/could/should support @PostConstruct & @PreDestroy annotations. Might be a good way to handle disconnections and so on when components are teared down while shutting down.

+1 for the annotations.
Thanks for the input. I did find the Lifecycle extension before I asked but that was not the right place.
RestartListener could work though even if I do not want to veto any restart from my plugin.

Regards,
Joachim

Plugin#stop() could help with this.

Thanks!

I think I found the intended location: ItemListener

    /**
     * @since 1.446
     *      Called at the begenning of the orderly shutdown sequence to
     *      allow plugins to clean up stuff
     */
    public void onBeforeShutdown() {
    }

which is called from Jenkins from e.g. doSafeExit():
    public void cleanUp() {
        for (ItemListener l : ItemListener.all())
            l.onBeforeShutdown();
