not found: value mavlinkDialect

I'm trying to connect ardupilot / px4 to a custom simulator developed in Scala, and was hoping to use sbt-mavlink
I've started a demo project to try to get it up and running but I'm getting the following error.
I'm probably doing something stupid as I don't have much Scala / sbt experience yet.
Any help would be great.

Error while importing sbt project:

OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=384M; support was removed in 8.0
[info] Loading global plugins from /home/peter/.sbt/0.13/plugins
[info] Loading project definition from /home/peter/IdeaProjects/mavlink-demo-oldsbt/project
/home/peter/IdeaProjects/mavlink-demo-oldsbt/build.sbt:9: error: not found: value mavlinkDialect
mavlinkDialect := "/home/peter/IdeaProjects/mavlink-demo-oldsbt/mavlink/common.xml"
^
[error] Type error in expression

My build.sbt file looks like this:

name := "mavlink-demo-oldsbt"
version := "0.1"
scalaVersion := "2.10.6"
enablePlugins(SbtMavlink)
mavlinkDialect := baseDirectory.value / "mavlink" / "common.xml"

plugins.sbt looks like this:

addSbtPlugin("com.github.jodersky" % "sbt-mavlink" % "0.5.1")

Thanks, Peter

Apologies, I needed to add the line:
import com.github.jodersky.mavlink.sbt.MavlinkKeys._
Still haven't managed to generate the source though, I've added the line:
sourceGenerators in Compile += mavlinkGenerate.taskValue to my build.sbt file but can't see where the source is being generated.
