@theaviary I get the following error while trying to build my first Griffon app:

@theaviary I'm using Java 11: $ java -version openjdk version "11.0.6" 2020-01-14

@theaviary Also, I'm using the gradle version specified by the wrapper: distributionBase=GRADLE_USER_HOME distributionPath=wrapper/dists distributionUrl=https\://services.gradle.org/distributions/gradle-4.7-bin.zip zipStoreBase=GRADLE_USER_HOME zipStorePath=wrapper/dists
