There are dependency errors loading some plugins: Jenkow Activiti Explorer v0.3.1 and Jenkow Activiti Designer v0.3.1

[Rainer Enders]

I just upgraded Jenkins to latest version 2.19.2 and without touching any Plugins, just purely by upgrading Jenkins, I now get an Error alert in the Manage Jenkins console:

There are dependency errors loading some plugins:

• Jenkow Activiti Explorer v0.3.1
  • jenkow-plugin v0.3.1 is missing. To fix, install v0.3.1 or later.
• Jenkow Activiti Designer v0.3.1
• jenkow-plugin v0.3.1 is missing. To fix, install v0.3.1 or later.
  

I am not aware I am using or need those plugins and all plugins we used previously did not have that dependency as far as I know. Also it appears those plugins are no longer available. How can I get rid of those error message or resolve the underlying problem? Seems a but in 2.19.2 to me.

These two plugins are installed on your instance:
- Jenkow Activiti Explorer
- Jenkow Activiti Designer

This one is not:
- Jenkow Plugin

The last one is a dependency of the other two (and has always been):
https://repo.jenkins-ci.org/webapp/#/artifacts/browse/tree/PomView/releases/com/cisco/step/jenkins/plugins/jenkow-activiti-explorer/0.3.1/jenkow-activiti-explorer-0.3.1.pom
https://repo.jenkins-ci.org/webapp/#/artifacts/browse/tree/PomView/releases/com/cisco/step/jenkins/plugins/jenkow-activiti-designer/0.3.1/jenkow-activiti-designer-0.3.1.pom

This could be an error in loading Jenkow Plugin (which will be shown in the Jenkins log), or just a side effect of stricter dependency checks when loading plugins. As the changelog would tell you:

> Fix plugin dependency resolution. Jenkins will now refuse to load plugins with unsatisfied dependencies, which resulted in difficult to diagnose problems. This may result in errors on startup if your instance has an invalid plugin configuration., check the Jenkins log for details.(issue 21486)

Therefore it may not be a bug, but rather a bug fix causing this.

One of these is the solution, depending on what is causing this:
- Install Jenkow Plugin.
- Fix whatever prevents Jenkow Plugin from loading.
- Or just uninstall Jenkins Activiti Explorer and Designer if you're not using them anyway.

Daniel,

I appreciate the quick follow and I thought exactly what you pointed out.
However there is no reference whatsoever about "Jenkow" anything. I
searched all the plugins and there is nothing in either the Installed nor
the Available section that contains the name "Jenkow" in any shape or
form.

See the attached screenshots. I do not think we have any Jenkow plugin
installed at all. So this looks like a bug to me.

Thanks.

Plugins that fail to load don't show up there, because they neither can be loaded, nor are disabled.

You'll find them in JENKINS_HOME/plugins.

Thank you very much. Problem solved.
