Dear Miles,
Actually, i tried it by hand, without scala:console and got the same problem. Do you have any recommendations?

It's missing scala.continuations.cps which is part of the runtime library rather than the plugin. If the library classfiles are all where you would expect them to be then my guess is that you've mistyped the classpath.

Dear Miles,
In the command line version i spotted the problem: a spurious $ prepended to the classpath. However, i've yet to spot the problem in the scala:console call. Best wishes, --greg

You would need to add the continuations plugin to the configuration for the maven-scala-plugin. I'm not sure this artifact is being deployed to the maven repository. I need to take a look.
