title: Error adding dependency to project
body: <p>I'm trying to add a library as a dependency but it keeps giving me this error:</p>
  
  <blockquote>
    <p>Class android.support.v4.accessibilityservice.AccessibilityServiceInfoCompat.AccessibilityServiceInfoIcsImpl
    has already been added to output. Please remove duplicate copies.</p>
    
    <p>Execution failed for task ':BrooklynTech:dexDebug'.
    Could not call IncrementalTask.taskAction() on task ':BrooklynTech:dexDebug'</p>
  </blockquote>
  
  <p>Here is my build.gradle:</p>
  
  <pre><code>buildscript {
      repositories {
          mavenCentral()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:0.6.+'
  
      }
  }
  apply plugin: 'android'
  
  repositories {
      mavenCentral()
  }
  android {
      compileSdkVersion 19
      buildToolsVersion '19.0.0'
      defaultConfig {
          minSdkVersion 14
          targetSdkVersion 19
      }
  }
      dependencies {
          compile files('libs/Simple-Rss2-Android.jar')
          compile 'org.jsoup:jsoup:1.7.3'
          compile 'uk.co.androidalliance:edgeeffectoverride:1.0.1'
          compile 'com.github.chrisbanes.actionbarpulltorefresh:library:+'
          compile project(':libraries:calendar-card')
          compile 'com.twotoasters.jazzylistview:library:1.0.0' }
  </code></pre>
  
  <p>the dependency I added was for jazzylistview - <a href="https://github.com/twotoasters/JazzyListView" rel="nofollow">https://github.com/twotoasters/JazzyListView</a></p>
  
  <p>How can I fix the error?</p>
