Installing SBT an Mac OSX 10.6 - scala

Question

I am trying to get SBT running on my Mac Operating System.
So far, I downloaded the Jar-Launcher and installed in into the /bin folder.
Then I created a SBT script, containing the following lines:
export PATH=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin:$PATH
java -Xmx512M -jar ` $0` /bin/sbt-launch-0.7.7.jar "$#"
When I call SBT on the Console, I receive the following series of error messages:
> /bin/sbt: fork: Resource temporarily unavailable
java.io.IOException: Cannot run program "sh": error=35, Resource temporarily unavailable

What is going wrong here?

Answer 1

Looks like you have a stray $0 there (which is expanded to the name of the current process sh). Try
java -Xmx512M -jar /bin/sbt-launch-0.7.7.jar "$#"
instead. That should get you up and running. The usual way is to call sbt like so:
java -Xmx512M -jar `dirname $0`/sbt-launch.jar "$#"
supposed you have the shell script sbt in the same folder as sbt-launch.jar because that is where dirname $0 points at.
