Hoping to get some troubleshooting tips. Trying to use dokka for a multi-module gradle project (with both java and kotlin sourcesets), and some projects are failing with the following error (full stacktrace in thread): 
java.lang.ClassCastException: class com.intellij.psi.PsiArrayType cannot be cast to class com.intellij.psi.impl.source.PsiClassReferenceType (com.intellij.psi.PsiArrayType and com.intellij.psi.impl.source.PsiClassReferenceType are in unnamed module of loader java.net.URLClassLoader @7dcea628)
Gradle version: 7.3.3 kotin/dokka plugin version: 1.5.31 and 1.6.10 (tried upgrading, same result on both) jdk: 11.0.13 platform: Intel Mac
Copy code

Hi! Looks rather strange. Is the project open source or have you been able to make a reproducible example by any chance? It would help greatly
p
The project is not open source, unfortunately. There are a few of the subprojects that are throwing this error, so I’m looking to see what they have in common, and failing that, I’ll see if I can try and figure out an SSCCE that I can push publicly. Either way, I’ll follow up with more info when I have something that may be useful. Is there any logging that I can enable in the dokka gradle plugin to figure out which particular files it’s trying to parse? Don’t seem to be getting much useful info from Gradle’s info/debug logging.
just to circle back, I was able to isolate the cause and have opened a ticket https://github.com/Kotlin/dokka/issues/2350

Nice, thank you so much! Im surprised this hasn't been caught earlier
p
No problem! Was glad I could isolate the issue, even if it took a bit (had to setup the dokka project locally and dig into the debugger to figure out what code elements were causing the break).
