java.lang.Throwable: psiElement is not instance of requiredClass

[kriegaex]

• IntelliJ IDEA 2023.3.4 (Ultimate Edition), Build #IU-233.14475.28, built on February 13, 2024
• Plugin version 0.12

Today, this happened one time in my IDE. Because it is unusual - I normally do not get errors from this plugin - I want to notify the maintainer.

java.lang.Throwable: psiElement is not instance of requiredClass.

Background: After a Spock version upgrade to 2.4-M2, one of my tests - GroovyMultipleAssignmentTest mentioned in the error message - started to fail compiling noth in Maven and IDEA. After a few more dependency upgrades, the error went away. But why it threw off the Spock Enhancements plugin, I have no idea.

Correction: I just noticed the path of the project. This is not the project where the compilation problem happened, but a small project meant to reproduce it, but without success. In that project, the error never occurred, which gave me a clue how to solve it in the big project, too. I.e., the plugin never threw this error in the problematic project, but in the new one which never had any compilation problems.
