Hi,

Thanks for looking into this.
What I did:

  1. Started Intellij
  2. Opened a project
  3. Saw the error at the bottom right corner where the notifications are:

    image1798×1256 117 KB

I have SonarQube configured to do the checks on commit, which also doesn’t work (I guess because the plugin fails to load).

Hey @Aleksandr_F, could you please share all the non-bundled plugins you use in your IDE?

You can do that by going to Menu -> Help -> About, click the Copy and Close button and share the result here.

Thank you!

The error message indicates a classloading conflict: the SonarQube for IDE plugin is trying to access com.intellij.util.lang.JavaVersion, but this class has been loaded twice within your IDE’s environment (classloader).

When this happens in a class related to SonarQube for IDE, the cause often points to another plugin providing an identical class, usually because of a forked version of our extension.

In your case, I’m not exactly sure how this happens. I see that kotlin recently added JavaVersion with the same package to their extension, so it might conflict with IntelliJ IDEA. However, I don’t reproduce the issue on my side with the same version as you.

I suggest you disable your non-bundled plugins and see if the issue happens again. Then you could re-enable them one by one until you find the plugin that is causing the issue.

Thanks!
