android - android-support-v4.jar 中的意外顶级异常

Question

我想编译我的应用程序时遇到问题:

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

看来是android-support-v4.jar的错误。

在我的项目中，我有 3 个库:appcompat、facebook、google_play_services。

我的 gradle 文件:

• 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')
  }
  

但是我编译的时候出现了这个错误:

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

你能帮帮我吗？

我发现了问题:

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')
}
