Not able to delete deprecated plugins

[Nagaraju Yarlagadda]

Hi Guys, 

I am not able to delete deprecated plugs. I am getting below errors. Please suggest how can I remove below plugin

Failed to load: Gitlab Hook Plugin (gitlab-hook 1.4.2) - Plugin is missing: ruby-runtime (0.12)

Thanks for asking.  The Ruby runtime plugin is deprecated.  It does not support Java 11 or Java 17.  Plugins that depend on the Ruby runtime plugin are deprecated.  They do not support Java 11 or Java 17.  Current versions of Jenkins require either Java 11 or Java 17.

Remove the gtilab-hook plugin file (gitlab-hook.jpi) and folder (gitlab-hook) from the plugins directory in your Jenkins home directory.  Remove any other plugins that are on the list in the "Deprecating non-Java plugins" blog post.

Thanks,
Mark Waite
