title: Error: java.util.zip.ZipException: duplicate entry
body: <p>I'm trying to add a library to my project, right now my current <code>build.gradle</code> is:</p>
  
  <pre><code>apply plugin: 'com.android.application'
  
  android {
      compileSdkVersion 21
      buildToolsVersion "21.1.2"
  
      repositories {
          mavenCentral()
      }
  
      defaultConfig {
          applicationId "com.example.guycohen.cheaters"
          minSdkVersion 11
          targetSdkVersion 21
          versionCode 1
          versionName "1.0"
              // Enabling multidex support.
          multiDexEnabled true
      }
      buildTypes {
          release {
              minifyEnabled false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
  }
  
  dependencies {
      compile fileTree(dir: 'libs', include: ['*.jar'])

      compile 'com.daimajia.androidanimations:library:1.1.3@aar'
  }
  </code></pre>
  
  <p>When I add a new library</p>
  
  <pre><code>compile 'com.github.navasmdc:PhoneTutorial:1.+@aar'
  </code></pre>
  
  <p>I get this error:</p>
  
  <pre><code>Error:Execution failed for task ':app:packageAllDebugClassesForMultiDex'.
  &gt; java.util.zip.ZipException: duplicate entry:      android/support/v4/print/PrintHelperKitkat$2$1.class
  </code></pre>
  
  <p>I've tried to fix this issue by adding</p>
  
  <pre><code>configurations { all*.exclude group: 'com.android.support', module: 'support-v4' }
  </code></pre>
  
  <p>I couldn't find a duplicate class in my project.</p>
  
  <p>I'm sure whether if I could delete the duplicate entry it would run perfectly, but I'm not sure how I'd find it. </p>
