Hi,
I have upgraded .war file to LTS 2.426.3 All [Config.xml under jobs > [jobname] is disappearing from jenkins server because of which jobs are not showing up in UI. all pipelines, jobs, and build history are missing. I tried with backup config.xml and still no luck. Most of the plugins are up to date. What’s wrong? It never happened before.
Have you updated all plugins after upgrading Jenkins? If not do so now.
When all pipeline jobs are missing, then probably the corresponding plugins failed to load thus the jobs can’t be shown.
Yes we have updated all plugins.
Ex: I have created Test folder in Jenkins UI and added few jobs under Test folder. Jenkins changes are getting reverted in on or 2 days. And one more issue after restart the service missing the job configs, build history UI and console.
Could it be that you have some custom way of starting your Jenkins? You should look what you’re doing there.
