Exception when configuring tests

[ColOfAbRiX]

If I add a configuration for testing, even if empty like:

wartremover {
  test {}
}

I get this exception and I can't configure tests:

> Failed to notify project evaluation listener.
   > java.lang.AbstractMethodError (no error message)

I'm using Scala 2.12.14, Gradle 6.6.1, gradle-wartremover 0.14.2

Hello, could you please try it in Gradle 7.x? 🙏

I'm afraid we don't plan to upgrade to gradle 7 anytime soon.
And thanks for your quick replies :)

Hello, unfortunately, we have all the projects in Gradle 7.x and the plugin works well there. As Gradle upgraded Groovy version when switching from 6.x to 7.x, maybe there is no workaround. It would be valuable if you could provide a Git repo with a minimal project to demonstrate the bug 🙏

The other day I had a quick look at past commits (down to version 0.12.0) and the code where this error seems to happen appear unchanged
