title: Android Unit Tests - no such property: bootClasspath
body: <p>I'm trying to execute a simple test case for Android following just announced unit testing support - <a href="http://tools.android.com/tech-docs/unit-testing-support">http://tools.android.com/tech-docs/unit-testing-support</a></p>
  
  <p>After carefully following the walkthrough I'm trying to run <code>./gradlew test</code>.
  I'm getting this error:</p>
  
  <pre><code>Execution failed for task ':app:compileDebugGroovy'.
  &gt; No such property: bootClasspath for class: com.android.build.gradle.AppPlugin
  </code></pre>
  
  <p>while using <code>com.android.tools.build:gradle:1.1.0-rc1</code>.</p>
  
  <p>Anyone else got stuck on that?</p>
