title: Upgraded android studio and get build error with gradle
body: <p>After upgrading to version 0.27 I get this error when trying to build and run my project:</p>
  
  <pre><code>Gradle: A problem occurred evaluating root project 'BeerPortfolioPro'.
  &gt; Gradle version 1.6 is required. Current version is 1.8-20130730220035+0000
  </code></pre>
  
  <p>My gradle file begins with this:</p>
  
  <pre><code>buildscript {
      repositories {
          mavenCentral()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:0.5.+'
      }
  }
  </code></pre>
  
  <p>I tried changing it to 1.6 and 1.8 and neither fixed the problem.</p>
