How to keep library dependencies updated to Scala version?

I am compiling my project with sbt and am getting an UNRESOLVED DEPENDENCIES error.

The fact is that I fetched the example I use (a hello world program) from an online blog, that uses scalaVersion := "2.10.0" as shown below. I am using 2.11.2.

How do I update the library dependencies (in the build.sbt) to the latest version of Scala, specifically the revision part?

build.sbt

name := "Hello Test #1"

version := "1.0"

scalaVersion := "2.10.0"

resolvers += "Typesafe Repository" at "http://repo.typesafe.com/typesafe/releases/"

libraryDependencies += "com.typesafe.akka" % "akka-actor_2.10" % "2.2-M1"

The error:

name := "Hello Test #1"

version := "1.0"

scalaVersion := "2.11.2"

resolvers += "Typesafe Repository" at "http://repo.typesafe.com/typesafe/releases/"

libraryDependencies += "com.typesafe.akka" %% "akka-actor" % "2.3.4"

This should do it. Note the %% and no version specified for the Akka artifact. Doing so, SBT will automatically append your Scala version to the artifact. See docs for more details.
