Build fails on Redhat 9

Hi

I'm trying to build Alpaca 2.2.0 on a Redhat 9 server, and its failing:

./gradlew clean build shadowJar

FAILURE: Build failed with an exception.

• What went wrong: Could not open settings remapped class cache for dbfphw7z841crfgakv4kncmip (//.gradle/caches/6.3/scripts-remapped/settings_2c91rbuqgcu40irth01tctxef/dbfphw7z841crfgakv4kncmip/settingsdeec0faa97453e2ce860d75e6bf1604b).

I've tried deleting the .gradle cache in my home directory and tried chmodding that cache directory to 777 and still the same error. I've also tried running the command with --no-build-cache and --no-daemon and they also failed, same error message

To reproduce: download the release bundle, uncompress it and run the command

Thanks Jon

Resolved - I was using java 22 on the system. I installed java 11 and it built fine. Not sure if the java 11 lib willwork with the java 22 vm yet
