title: Eclipse ADT plugins are not able to update to 21.0 version
body: <p>I have updated the Android SDK tools to 21 version in Android SDK. But when I open my eclipse it says to update the ADT tools in eclipse as SDK version is 21.0.</p>
  
  <p>So I also tried to update the eclipse plugin but it is not updating and so I can not write code now. So What should I do to update ADT tools for eclipse?</p>
  
  <p>I appreciate you answer if you have.</p>
