Sbt heapsize is not enough?

Question

When I try to compile scalala , I get OutOfMemoryError:

I don’t know much about SBT, so I don’t know what I am doing wrong. In the sbt file, I changed to:

 java $SBT_OPTS -Dfile.encoding=UTF-8 -Xss4M -Xmx1024M -XX:MaxPermSize=1024M -XX:NewSize=512M -XX:NewRatio=3 -jar `dirname $0`/project/sbt-launch-0.7.5.jar "$@" 

Build.properties:

 #Project properties #Mon Apr 11 02:52:55 PDT 2011 project.organization=org.scalala project.name=scalala sbt.version=0.7.4 project.version=1.0.0.RC2-SNAPSHOT def.scala.version=2.9.0 build.scala.versions=2.9.0 project.initialize=false 

The same problem occurred when compiling for scala 2.8.1.

How do I compile scalala?

Thanks for any help!

Answer 1

Try increasing the heap size a bit, in sbt put:

 -Xmx1524M 

Answer 2

Team

sbt can read the JAVA_OPTS or SBT_OPTS environment variable. Co you can try:

$ JAVA_OPTS = -Xmx1524M

If this does not work and you are using OpenJDK for Linux based OS, you can also try the following:

 # echo 1 > /proc/sys/vm/overcommit_memory 

Answer 3

Just setting SBT_OPTS may not work, because after that the JAVA_OPTS tag appears, and at least my java version "1.7.0_80" uses the last flag to set heapsize.
