How to make app resources accessible to sbt console initialCommands?

I'm using sbt 0.11 and Scala 2.9.1 (which appears to evaluate REPL lines in the same thread). In my build.sbt I have:

initialCommands in console := """
println(Thread.currentThread)
println(Thread.currentThread.getContextClassLoader)
ru.circumflex.orm.Context.get() // reads my src/main/resources/cx.properties
"""

Context.get() loads resources with:

val bundle = ResourceBundle.getBundle(
  "cx", Locale.getDefault, Thread.currentThread.getContextClassLoader)

This results in an error (the REPL appears to buffer up its own output after stdout/stderr):

> console

Removing the last initialCommand line and running it in the REPL results in no error, since by that time the resource is visible.

Any hints on how to deal with this and make my app's resources accessible to initialCommands?


Discovered the answer soon after posting this. Just prepend this line to initialCommands:

Thread.currentThread.setContextClassLoader(getClass.getClassLoader)
