I just built AD 3.0.0 without problems.

I saw the error is:

* What went wrong:
Could not open settings generic class cache for settings file '/tmp/tmpnnchbo3y/anomaly-detection/settings.gradle' (/usr/share/opensearch/.gradle/caches/7.6.1/scripts/f2pbr3693ueh1pzcvl0sbr014).
> BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 64

What does "settings generic class cache" mean?

I think we are now using JDK20 (https://github.com/opensearch-project/opensearch-build/blob/aa65a8ecd69f77c3d3104043dd1c48dff708bffa/manifests/3.0.0/opensearch-3.0.0.yml#L9) and gradle version 7.6.1. It looks like the current gradle version doesn't support JDK20.

@kaituo Could you help upgrade the gradle version so it starts to support Java 20 for the main branch?

Also make sure we include java 20 in your CI matrix.
