How to get full stacktrace in SBT 0.10.0?

I'm using SBT 0.10.0 to compile a combination of Java and Scala files. When I run the program through sbt run it returns a nonzero error but doesn't show me a stacktrace -- it simply fails silently with the cryptic message:

Nonzero exit code: 1

If I run the program through scala command line, it does show the stacktrace.

Is there any way 开发者_如何学运维I can get SBT to print out the entire stacktrace?

Execute sbt to get into the sbt shell, then try run followed by last run.

last <command> outputs everything that the command produced (all log levels, including [debug]) and stacktraces.

last run, as shown here, is the way to go, but it can be annoying if you are doing something like running in a loop with ~ run and just want to see your app's exceptions. You can tell SBT to enable printing the stack traces automatically for a task like this:

traceLevel in run := 0

Further reference here.

In SBT 0.13.x, the stack trace's printed out so the question might've become irrelevant now.
