title: Android Studio 1.0 failing build at dexDebug or dexRelease
body: <p>I recently upgraded from Android Studio 0.9.2 to 1.0 (including version 1.0.0 of the Gradle plugin) and I'm having an issue with building my project.</p>
  
  <p>Whenever I build I get the following exception at the dexDebug or dexRelease step:</p>

  <p>I tried increasing the heap size of Android Studio to <code>-Xmx4096m</code> but to no avail.
  In Android Studio 0.9.2 with version 0.14 of the gradle plugin building worked fine.</p>
  
  <p>This is the build.gradle file of my project:</p>
  
  <pre><code>// Top-level build file where you can add configuration options common to all sub-projects/modules.
  buildscript {
      repositories {
          mavenCentral()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:1.0.0'
      }
  }
  </code></pre>
  
  <p>And this is the build.gradle file of my module:</p>
