Unexpected Top-Level Exception in android-support-v4.jar

Question

I have a problem when I want to compile my app:

UNEXPECTED TOP-LEVEL EXCEPTION: java.lang.IllegalArgumentException: already added`

It seems to be a error with android-support-v4.jar.

In my project I have 3 libraries: appcompat, facebook, google_play_services.

My gradle files:

• AppProject/settings.gradle

  include ':libraries:google_play_services', ':libraries:appcompat', ':libraries:facebook', ':app'
  

• AppProject/build.gradle :

  buildscript {
      repositories {
          mavenCentral()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:0.5.+'
      }
  }
  

• AppProject/app/build.gradle:

  apply plugin: 'android'
  
  dependencies {
      compile project(':libraries:appcompat')
      compile project(':libraries:facebook')
      compile project(':libraries:google_play_services')
      compile files('libs/android-async-http-1.4.3.jar')
      compile files('libs/gson-2.2.4.jar')
      compile files('libs/libGoogleAnalyticsV2.jar')
      compile files('libs/universal-image-loader-1.8.4.jar')
      compile files('libs/urbanairship-lib-3.0.0.jar')
  }
  

• AppProject/libraries/appcompat/build.gradle:

  apply plugin: 'android-library'
  
  dependencies {
      compile files('libs/android-support-v4.jar')
      compile files('libs/android-support-v7-appcompat.jar')
  }
  

• AppProject/libraries/facebook/buidle.gradle:

  apply plugin: 'android-library'
  
  dependencies {
      compile files('libs/android-support-v4.jar')
  }
  

• AppProject/libraries/google_play_services/buidle.gradle:

  apply plugin: 'android-library'
  
  dependencies {
      compile files('libs/google-play-services.jar')
  }
  

But when I compile it, this error appears:

Output:
        UNEXPECTED TOP-LEVEL EXCEPTION:
        java.lang.IllegalArgumentException: already added: Landroid/support/v4/app/NotificationCompatIceCreamSandwich;

Can you help me?

I found the problem :

AppProject/settings.gradle

include ':libraries:facebook', ':app'

AppProject/libraries/facebook/build.gradle

apply plugin: 'android-library'

dependencies {
    compile 'com.android.support:support-v4:18.0.0'
}

AppProject/app/build.gradle

apply plugin: 'android'

dependencies {
    compile 'com.android.support:support-v4:18.0.0'
    compile 'com.android.support:appcompat-v7:18.0.+'
    compile 'com.google.android.gms:play-services:3.1.36'

    compile project(':libraries:facebook')
    compile files('libs/android-async-http-1.4.3.jar')
    compile files('libs/gson-2.2.4.jar')
    compile files('libs/libGoogleAnalyticsV2.jar')
    compile files('libs/universal-image-loader-1.8.4.jar')
    compile files('libs/urbanairship-lib-3.0.0.jar')
}
