I have a deprecated Jenkins plugin installed (WMI Windows Agents Plugin, v1.8.1), and I'm trying to uninstall it.
Problem
When I uninstall the plugin from the Jenkins web UI, it gets stuck at "Uninstallation pending" no matter how long I wait.
What I Tried
When I do a safe restart after a long wait, the UI shows that the plugin is still installed, as if I had not attempted an uninstall. I also tried disabling the plugin before attempting another uninstall—still stuck at pending uninstallation. Doing a yet another safe-restart after a long wait doesn't work either.
After you click uninstall, while the status is "Uninstallation pending",
click on Available Plugins and without selecting any plugins click on Download now and Install after Restart.
For some reason this completes the uninstallation
I initially couldn't uninstall the WMI Windows Agents Plugin on Jenkins 2.375.2 either.
This comment on JENKINS-70454 suggested that upgrading to Jenkins 2.375.3 might help, and indeed:
I could uninstall the plugin as expected after upgrading.
FWIW: I assume that hudson.PluginManager#considerDetachedPlugin was somehow responsible for keeping that plugin, as
journalctl -ujenkins | grep windows
showed me
hudson.PluginManager#considerDetachedPlugin: Loading a detached plugin as a dependency: /var/lib/jenkins/plugins/windows-slaves.jpi
after every reboot (but to be honest, I don't know much about detached plugins).

I have updated my jenkins server and see the following message for some plugins. I am not sure how to fix this. I looked at the dependencies section for that plugin and I see they are already installed. Not sure what else is missing so I can see the update available. Dependency for this is Mailer which is already installed on my server.
That is frustrating but you can try uploading plugins manually.
You can download plugins from here link to plugin storage.
Of course you have to roughly see what version of the plugin goes with your jenkins version.
Once you downloaded 'proper' plugin version, you go to manage plugins, advanced tab and there you can upload the plugin file. After that restart jenkins and check changes. You should really go to manage plugins, updated plugin tab and update selected plugins...
It could be guess work, but I'm sure after a couple of guesses you'll get to the version of Jenkins you have.
You might need to upgrade jenkins.. here are all jenkins war files:
https://get.jenkins.io/war-stable/
Last but not least... don't try to fix all dependencies.. fix those you use, rest is optional.
we have upgraded jenkins. war to the latest version and we can see the latest version in Jenkins console as well.
But the issue is when we open add/or remove programs from control panel it is still pointing to the old version. Please let me know what can be done to resolve the issue.
You don't have to do anything. This will have no effect on your set up. Though Add or remove programs will show the earlier version that you installed but whenever you decide to uninstall it, it's going to uninstall whichever version will be present in your Jenkins installation directory.
Note: What i have observed is that it actually removes the Windows service when it uninstalls but leaves the Jenkins installation directory structure intact.
I realize that this question has been asked before but I feel like my case is different.
About five hours after I launch jenkins I sometimes see this message appear when loading the jenkins administrator panel:
Jenkins detected that you appear to be running more than one instance of Jenkins that share the same home directory '’. This greatly confuses Jenkins and you will likely experience strange behaviors, so please correct the situation."
This is strange, it happens every time I launch it, eventually making Jenkins unusable. I installed Jenkins via homebrew and launch is via the jenkins CLI. I manually do this so I don't see how it's possible that Jenkins launches twice.
I reinstalled Jenkins after completely removing it. Still no luck.
Anyone have any issues like this before?
I also had a similar problem and solved it with following checks:
Check if another java process is running which runs jenkins e.g. in unix using top
If you're using tomcat, search for a second instance of tomcat having the jenkins.war exploded somewhere
Could be helpful to just have one version of java installed
Today I noticed that several of our Jenkins jobs (which are independant, different projects and everything) failed.I investigated an finally listed all processes on the machine that Jenkins uses with the top command. It showed me a very greedy process launched by Jenkins, which name is iLmBjh. Not very clear, isn't it?I tried some things and finally killed it. But it appeared again when I launched a new Jenkins job.Do someone know what this process does? It's the first time I see it on the processes list...
Ok, I guess I found the problem and it's kind of surprising. On our Jenkins instance, we had the JiraTestReporter plugin installed. Our Jira licence ended today. And when I checked the Jenkins logs, it was full of Jira error messages.What is disturbing is that we weren't using it at all... in any of our jobs!I uninstalled it and was able to run my job again. The iLmBjh process did not come back.
I have a question about updating GitHub plugin.
Everytime I do an update plugin such as GitHub and restart the jenkins, Jenkins start crashing. when I try to access jenkins through URL in my browser, the error page shows up with some exception "class not found jenkins/model jenkins" . and then in order to make jenkins working again , I have to delete the plugin entirely from the plugins directory. I wish someone has an answer for this because I really need to make my github projects available to jenkins for build. Thanks
It is a very usual problem with Jenkins. My workaround was to either update the jenkins (where ever it is installed) and restarting the hudson service.
sometimes even restarting the service works.
often you might need to remove those plugins from within (/var/lib/hudson/plugins/) and restart the service.
