Dump classpath used for sbt run?

[Sean Rhea]

All,

In development I run my program like this:

sbt run "--foo bar"

and that works fine. But in production use, I want to pass particular
arguments to the JVM, and I don't need to load sbt. So I end up doing
something like

CLASSPATH=`find lib* -name '*.jar' | xargs echo | sed -e 's/
/:/g'`:project/boot/scala-2.8.1/lib/scala-library.jar:target/scala_2.8.1/classes
java -Xmx32M my.class.Name --foo bar

Is there a better way to do that? Something like

CLASSPATH=`sbt dump-classpath` java -Xmx32M my.class.Name --foo bar

Any pointers on how I might write one if not?

Thanks,
Sean

I was dumping my classpaths as a way to troubleshoot my build recently and maybe this task can help you too:

lazy val printClasspath = task { this.runClasspath.getPaths.foreach(println); None }

runClasspath is a PathFinder [1] instance and you can interrogate it even further. I guess building a ':'-separated list of those paths will be easy.
