After much debugging, found the correct way of setting the gradle application JVM options via the Application plugin settings in the build.gradle
It does however need a large 2g heap to succeed for the failing jdk11u publishes.

The new jenkins_worker has jdk-21, so had to upgrade gradle to support that.
