how can I know whether the plugin is used by any jobs in jenkins

Question

Jenkins had 600+ plugins, in the real system, we are used to install lots of plugins.

And sometimes, we want to remove some plugins to make system more clean or replace

Answer 1

As of early 2018 there is a "Plugins Usage Plugin" that gives you a nice list of the plugins and where they are used. We've noticed that depending on the system sometimes it doesn't seems to catch all the plugins, but it gives a really lovely list of the plugins and all jobs related to a specific plugin in an expandable list.
