Henrik commented on GROOVY-8779: -------------------------------- I'm currently unable to switch to using java 8, since the code base is thoroughly changed to java10. I am specifying bytecode version 10 a couple of places in the intellij preferences & project settings. I tried using 2.5.3-SNAPSHOT, and now it works. Yay! Do you know which specific change in this version that fixed the issue? > Groovy 2.5.2 triggers a bug in IntelliJ IDEA > -------------------------------------------- > > Key: GROOVY-8779 > URL: https://issues.apache.org/jira/browse/GROOVY-8779 > Project: Groovy > Issue Type: Bug > Affects Versions: 2.5.2 > Environment: Mac OSX High SIerra > Reporter: Henrik > Assignee: Paul King > Priority: Major > Fix For: 3.0.0-alpha-4, 2.5.3 > > > I have a Java 10.0.2 / Groovy 2.5.1 project in IntelliJ IDEA 2018.2.3.
