Hi, I've created a new Grails 3.3.10 app and TravisCI is failing, I got the same problem with OpenJDK 11 Unzipping /home/travis/.gradle/wrapper/dists/gradle-3.5-bin/daoimhu7k5rlo48ntmxw2ok3e/gradle-3.5-bin.zip to /home/travis/.gradle/wrapper/dists/gradle-3.5-bin/daoimhu7k5rlo48ntmxw2ok3e Set executable permissions for: /home/travis/.gradle/wrapper/dists/gradle-3.5-bin/daoimhu7k5rlo48ntmxw2ok3e/gradle-3.5/bin/gradle FAILURE: Build failed with an exception. * What went wrong: Could not determine java version from '9.0.4'.
