Scala version not updating

My project used Scala version 2.10.2. I am trying to update to 2.11.4. I have updated my build.sbt.

But now when I run sbt compile it still shows me Resolving org.scala-lang#scala-library;2.10.2 .... I believe it means that my Scala version hasn't been updated. What am I doing wrong?

You can always use show to see the value of any setting:

% sbt
[info] Loading project definition from ...
[info] Set current project to ...
> show scalaVersion
[info] 2.12.0-M1

scalaVersion tells you which Scala version your project is built with. You can also verify it using console:

> console
[info] Starting scala interpreter...
[info] 
Welcome to Scala version 2.12.0-M1 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_45).
Type in expressions to have them evaluated.
Type :help for more information.

scala> scala.util.Properties.versionString
res0: String = version 2.12.0-M1

This may be different from the Scala version used to compile your build definition. sbt 0.13 always uses Scala 2.10 for that:

> eval scala.util.Properties.versionString
[info] ans: String = version 2.10.4

You can't change that; it's determined by the sbt version.
