The current build of cucumber-jvm is built against Scala 2.10.0-RC1. This means that it won't run on a project using Scala 2.9.2. These projects are restricted to cucumber-jvm version 1.0.9.
It should be possible to cross build cucumber-scala for both Scala 2.9.2 and 2.10.0-RC1 so that the plugin can build against the latest version.
