..because it depends on the scala-repl, which isn't by default in the runner script.

Wow nice catch! Looks like we should use reflection to make repl-specific and maybe also scaladoc-specific parts of the code more robust. Is this a blocker for you?

Thanks for the quick answer. It's more of a "nice to have" than a blocker, I'm often testing/debugging outside of Sbt on real-life projects. I can work around by manually adding the Repl to the classpath.
