FAILURE: Build failed with an exception.

* What went wrong:
Could not open cp_settings generic class cache for settings file '/github/spring-authorization-server/settings.gradle' (/Users/xxxxxx/.gradle/caches/8.6/scripts/8p1dsh50yfy2z8nn9b37nu6aq).
> BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 66

To Reproduce Got a fresh clone of the repo and ran: ./gradlew -b samples/demo-authorizationserver/samples-demo-authorizationserver.gradle bootRun

Expected behavior Working samples

If that matters: The samples worked for me some month ago. I've switched to a Macbook M3 and now have java 22 running.

@konstantinj Maybe this helps https://docs.gradle.org/8.6/userguide/compatibility.html#java

A Java version between 8 and 21 is required to execute Gradle. Java 22 and later versions are not yet supported.

@konstantinj As noted
