Groovy Compiler runs out of memory

Hello guys,

I've a problem compiling my Grails-project, because the Groovy compiler runs out of memory (build log is attached below). I've tried various settings, but none of them worked. I tweaked all the different UI settings regarding the compiler / build process, and I added "groovy.compiler.Xmx=4096M" to the ideas.properties file. But the JVM process, that IntelliJ launches for the groovy compiler, is always configured with "-Xmx400m", as JVisualVM depicts.

Is it even possible to increase the heap size for the groovy compiler? Or may the compiler run in the same JVM as IntelliJ?

Thank you and best regards.
