Is there a solution to this issue?

Still happening. Mine came when trying to generate unit tests for a class.

i had the same issue, when i tried create a test class apears the same message.

This happen because you dont have the folder src/test/java. In my case i forgot add the java subfolder

When i added the subfolder java i solved this issue and i can use the plugin
