scala 2.11 and the upgrade to 2.1.1

I just updated my pom with this:

`

<properties>
   <maven.compiler.source>1.6</maven.compiler.source>
   <maven.compiler.target>1.6</maven.compiler.target>
   <scala.version>2.11</scala.version>
   <encoding>UTF-8</encoding>

`

and assumed it would work.

Running mvn clean install, however, gives me the blow build error, how can i fix it?

Failure to find org.scala-lang:scala-library:jar:2.11 in http://repository.excilys.com/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of excilys has elapsed or updates are forced → [Help 1]

When we say we target Scala 2.11, it’s really "we target Scala 2.11.x”.
2.11 is only the major version.
It that case the correct version is not 2.11, but 2.11.4.

Downloading 2.11.4 via SBT now.
Thanks.
