Alternately, use "console-quick", which brings up a console with your dependencies on the classpath, but not your actual code.

As a (lengthy) side-note, that name really bugs me. In sbt, we have console-quick and console-project (brings up a console with your build on the classpath). Argh! These are kinds of consoles. They should be quick-console and project-console! Alas, those are the names that Mark Harrah gave us, so they're the ones we have to live with, I guess.
