I have a mixed java/gorrvy project., IntelliJ IntelliJ IDEA 2019.3.2 (Community Edition) Build #IC-193.6015.39, built on January 21, 2020
I want to use JDK 13 preview features, so I turned it on in java language.
But now groovyc fails
Preview features are not enabled for utils/annotation/Nullable (class file version 57.65535). Try running with '--enable-preview'
I want to add '--enable-preview' to groovy compiler, see https://issues.apache.org/jira/browse/GROOVY-9073
but can't find how to do it
