If you are using groovy console and want to enable the new parser Parrot, just set the environment variable JAVA_OPTS=-Dgroovy.antlr4=true
P.S. setting environment variable GROOVY_OPTS=-Dgroovy.antlr4=true does NOT work. Cheers, Daniel.Sun -- Sent from: http://groovy.329449.n5.nabble.com/Groovy-Dev-f372993.html
