title: SBT, Scala version mismatch
body: <p>i have installed <code>Scala 2.11.8</code> version, and i installed <code>SBT 0.13.12</code> version as well.</p>
  
  <p>when i create one directory and inside that directory typed sbt and sbt prompt opened. Inside <strong>SBT prompt</strong>, when i checked <strong>libraryDependencies</strong> i found like this: </p>
  
  <pre><code>sbt:sparkp&gt; libraryDependencies
  [info] * org.scala-lang:scala-library:2.12.4
  </code></pre>
  
  <p>But in machine, i have installed <code>scala 2.11.8</code> version, when i checked <strong>scala -version</strong> it shows </p>
  
  <pre><code>hadoop@localhost:~$ scala -version
  Scala code runner version 2.11.8 -- Copyright 2002-2016, LAMP/EPFL
  </code></pre>
  
  <p>Did i made any mistake while installing <strong>sbt</strong>? or i need to change any configuration properties after installation?</p>
  
  <p>please help out.</p>
  
  <p><strong>Note:</strong> There are some questions regarding this error in <strong>stackoverflow</strong>, but i didn't get exact answer that's why i am asking new question.</p>
