Running with fresh install and default settings against build 41 gives an error like: ``` zombie/Lua/LuaManager has been compiled by a more recent version of the Java Runtime ``` Changing the following line in zdoc.gradle (176): ``` languageVersion = JavaLanguageVersion.of(8) ``` to ``` languageVersion = JavaLanguageVersion.of(15) ``` fixes the issue for me. Not sure if 15 is the right version to pick but it gets the job to run happily and autocomplete works like a charm.
