You can enable the Parrot parser using -Dgroovy.antlr4=true (set via JAVA_OPTS if needed). The new parser supports do/while loops, classic array initialization, !in/!instanceof operators, === identity operator, safe indexing, try-with-resources, Java lambda and method reference syntax, Elvis assignment operator and much more... Note: If building Apache Groovy from the source distribution yourself, you need to bootstrap the Gradle wrapper using a version of Gradle prior to 4.0. Best regards, The Apache Groovy team.
