I used it with play framework, but the generation doesn't started automatically

[wuhuajie]

my steps:

1. in build.properties add
   sbt.version=1.3.10

2. in plugins.sbt add:
   addSbtPlugin("com.intenthq.sbt" % "sbt-thrift-plugin" % "1.1.0")

3. in build.sbt add
   import com.intenthq.sbt.ThriftPlugin._
thriftSourceDir := file("app/thrift/")
libraryDependencies ++= Seq( "org.apache.thrift" % "libthrift" % "0.9.3" )

4. But the sbt-thrift-plugin is not started. What is missing?

Thank you.
