I have big grails project (five modules + 2 custom no pre-compiled plugins).
At first – compilation was failed with out of memory in javac. I added as params:
-J-Xmx1024m -J-Xms512m -J-XX:MaxPermSize=2048m
great, first OOM – fixed.
At second – I have OOM in groovy compiler. How to pass memory params from Idea to groovyc? Also my application should work in NOT forking mode
You don't set the groovyc memory directly. You should set/increase your memory settings directly in the IntelliJ settings. The documentation can be found here: https://www.jetbrains.com/idea/help/increasing-memory-heap.html
In general, in your IntelliJ installation's bin folder, there will be 2 files of interest: idea.exe.vmoptions and idea64.exe.vmoptions. You would adjust the settings for the file that matches the idea.exe or idea64.exe you use to launch IntelliJ
Within the file, you can adjust your heap memory for IntelliJ as a whole. My guess is you are running out of perm gen space and should increase your MaxPermGenSize. The settings would looks similar to this (I have 16gb memory on my PC):
-Xms750m
-Xmx2g
-XX:MaxPermSize=350m
