scala - sbt heapsize 不够？

Question

当我尝试编译时 scalala我得到一个 OutOfMemoryError:

> compile
[info] 
[info] == compile ==
[info]   Source analysis: 127 new/modified, 0 indirectly invalidated, 0 removed.
[info] Compiling main sources...
[info] == compile ==

我对 SBT 了解不多，所以我不知道我做错了什么。
我改成的sbt文件:

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

为 scala 2.8.1 编译时出现同样的问题。

我怎样才能编译 scalala？

谢谢你的帮助!

尝试稍微增加堆大小，在 sbt put 中:

-Xmx1524M
