I dont know much about SBT so I dont know what I am doing wrong. 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 occured when compiling for scala 2.8.1.

How can I manage to compile scalala?

Thanks for any help!

Answer 1

Try to increase heap size a bit, in sbt put:

-Xmx1524M

Answer 2

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

$ JAVA_OPTS=-Xmx1524M

If that doesn't work and you are using OpenJDK on a Linux based OS, then you can also try this:

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

Answer 3

Just setting SBT_OPTS may not work as the JAVA_OPTS appear after those and at least my java version "1.7.0_80" uses the last flag to set the heapsize.
