How do I increase Groovy's JVM Heap Size?

Question

Some sources on the web claims that I should be able to give the -Xmx param to groovy but that just gives me java.io.FileNotFoundException when it can't find the -Xmx file. Other sources tell me to set some variable named JAVA_OPTS but how do I do that? And how do I know if it worked?

Answer 1

$ export JAVA_OPTS="$JAVA_OPTS -Xmx64M"
$ groovy

Answer 2

UPDATED: Go to your Groovy home folder and go into the bin directory. In startGroovy.bat, you can set it from 128MB to 512MB like this:

...
@rem set GROOVY_OPTS="-Xmx128m"
set GROOVY_OPTS="-Xmx512m"
