Specifying the Jetty port in SBT 0.10

I need to run the embedded Jetty on port different to the default 8080, using SBT 0.10 The question was answered here for SBT 0.7 - In which file do I need to add an override for the jetty port when running a lift webapp in dev mode from sbt?. I can find no reference to do the same for SBT 0.10 I am using the Full configuration (Build.scala) for multi modules and not quick the sbt dsl.
