Sbt: why does it need scala-lang 2.10.3?

Question

My build.sbt:

import android.Keys._

android.Plugin.androidBuild

name := "teacher-journal"

scalaVersion := "2.11.0"

proguardCache in Android ++= Seq(
    ProguardCache("org.scaloid") % "org.scaloid"
)

proguardOptions in Android ++= Seq("-dontobfuscate", "-dontoptimize", "-dontwarn scala.collection.mutable.**")

libraryDependencies += "org.scaloid" %% "scaloid" % "3.3-8"

scalacOptions in Compile += "-feature"

run <<= run in Android

install <<= install in Android

It gives me an error:

Sbt 0.13.2, system scala 2.10.2, java 8, fedora 20. Why does it need scala 2.10.3 and how to fix an error?

Everything works for my friend with similar configuration on Ubuntu.

Fixed by cleaning ~/.sbt and ~/.ivy2
