NoClassDefFoundError: com/virtuslab/contextbuddy/ContextBuddy$

I get a NoClassDefFoundError immediately after starting up IntelliJ.

Stack trace:

Is context buddy open source? I wonder if I could contribute a fix for that..

I need to add that this error occurs after I try to install Context Buddy using IntelliJ's Plugin Marketplace. I noticed that the blog recommends to download the plugin from some other place. Can it be due to that? If so, can the version at the marketplace be updated?

By the way, the pasted stacktrace doesn't show up when I did the following:

1. uninstalled the plugin, restarted the IDE
2. installed the plugin, but without restarting the IDE
3. modified the downloaded zip in ~/.cache/JetBrains/IdeaIC2020.1/plugins the following way:

• packaged the classes directory into a context-buddy.jar
• removed the classes directory
• pasted the created jar into lib next to other jars

4. restarted the IDE

Then the menu actions are available though I can click on anything and nothing happens, apart of the help.

The plugin downloaded from the link at the blog also generates this error.

When I repackaged the version mentioned at the blog post (moved contents of classes into a jar in lib), the Context Buddy was able to display some UI elements:

but then I can't do anything useful with that and I can see the following in the Idea log:
