Does anyone have a working TravisCI configuration for Grails 3.3.x? I'm in 3.3.10 and my tests run with gradlew and failt with OpenJDK >= 9: FAILURE: Build failed with an exception. * What went wrong: Could not determine java version from '9.0.4'. On some groups they point to use Gradle > 5 and Grails 3.3.10 seems to have Gradle 3.5.
