scala - How to set heap size in play/activator? -


I get "java.lang.OutOfMemoryError: Java heap space" when you run activation. I want to set the stack in unlimited size. I read somewhere that I somehow need this kind of change SBT_OPTS or _JAVA_OPTION: 

  Export SBT_OPTS = "- Xmx2G -XX: + UseConcMarkSweepGC -XX: + CMSClassUnloadingEnabled -XX: MaxPermSize = 2G-XSS2M -Deser.timezone = GMT "

I did not find any documents anywhere on this.

tl; dr Activator -ship

You can use JAVA_OPTS can affect (other Java programs), SBT_OPTS (SBT also affected), ACTIVATOR_OPTS enable) and there is also a -mem flag that you can use.

I think -J-Xmx512M will also work.
