Scala 2.10 and Akka 2.0 and 2.1 import problems (Await, Future, Duration)

As a quick note, import statements that used to be like this with Akka 2.0:

import akka.dispatch.Await
import akka.dispatch.Future
import akka.util.duration._

are now like this with Akka 2.1 and Scala 2.10.x:

import scala.concurrent.{Await, Future}
import scala.concurrent.duration._

The Duration object in Akka 2.0 has also been moved, and it’s now included with the scala.concurrent.duration._ import statement.

If you’re seeing compiler error messages like this when trying to compile your Scala 2.10 and Akka 2.1 project:

object Await is not a member of package akka.dispatch

you (probably) have this problem, and changing your import statements as shown will solve your problem.


You may also need this import statement for your Future expressions:


If you are using the Scala IDE project with Eclipse, it gives you part of that information, but not all of it.
