Stupid GMail sent the message before I was done... The rest of the error says: "phase 'semanic anaylisis' in source unit '__BuildScript_' Unsupported major class version 63"
I.e. it is trying to use Gradle 7.5 while NetBeans is running on JDK 19 and failing. What is interesting is the first message - that Java 19 is not supported by Gradle 7.6. That is false. 7.6 is when Gradle gets Java 19 support. The suggestion to downgrade to 7.5 which is known not to work is a little funny. Basically the release notes for NetBeans 16 should mention that Gradle projects don't work if you run the IDE with JDK 19, JDK 17 should be used instead.
