scala: delimited continuation issues

Question

Here is a code I have problem to compile. My question is very simple. How to fix compilation error?

I did try to run this from sbt and from command prompt. SBT configuration below. I did add references to continuation plugin! But looks like this is not helping! See error below.

I've got this from scaladocs: http://www.scala-lang.org/files/archive/api/2.11.8/scala-continuations-library/#scala.util.continuations.package

    object MainApp 
    {
       def main(args: Array[String]): Unit = 
       {
        import scala.util.continuations._

         val uuidGen : String = "UniqueValue"

def ask(prompt: String): Int @cps[Unit] =
  shift {
        k: (Int => Unit) => {
        val id = uuidGen
            printf("%s\nrespond with: submit(0x%x, ...)\n", prompt, id)
        }
}

def go =
    reset {
         println("Welcome!")
         val first = ask("Please give me a number")
         val second = ask("Please enter another number")
         printf("The sum of your numbers is: %d\n", first + second)
}

      go

     }
   }

Sbt configuration for the refrences
