Hi,
I am trying to manage jenkins plugins with helm values.yaml config file. When I compare my config file with plugin list in Dashboard => Manage Jenkins => Plugins => Installed plugins, I saw that values.yaml does not incluede plugins workflow-cps-global-lib, popper2-api, jsch,ace-editor, javax-mail-api, command-launcher,aws-java-sdk. I checked them on Jenkins dashboard and see I can uninstall them (so they are not dependency to other plugins) to sync plugin config with actual state. However they enter Uninstallation pending state, comes back when I restart jenkins. How can I delete these plugins and what could be the reason of this situation?
Thank you

I noticed a similar issue but with fewer plugins than you. Several plugins used to be part of the core of Jenkins such as maven, svn, etc… and these would always come back no matter what I did. In newer versions of Jenkins this seems to have improved but I still see a few remaining plugins that always come back. We are on the latest 2.440 LTS so there are less of these plugins, so maybe you can try with 2.440 and see if you are able to get rid of more plugins.

I would check the version of your helm chart as well. The init container logic has changed in newer versions. We are still on an older chart (v3.x IIRC), but we plan on upgrading to the latest chart as soon as we get some free cycles to test and deploy it (older chart upgrades broke many things, but that should not be the case anymore).

The issue you’re experiencing might be due to the fact that these plugins may be dependencies of other plugins that are still installed in your Jenkins instance. Even if the Jenkins UI doesn’t explicitly list them as dependencies, they might still be required by other plugins. :person_shrugging:

Plugins like ace-editor are obsolete. They can be uninstalled and they should not come back. This can only happen when there is some other process, that fills the plugins directory.
Some other plugins like javax-mail-api will come back if you have an older plugin installed that might implicitly depend on it. I was also not able to permanently remove. But what works is to disable the plugin and then it stayed disabled.
