Android Studio＆Gradle：多個dex文件

Question

今天我遷移到Android Studio 1.1並開始更新某些庫的版本。當我使用gradle按鈕構建項目時，一切看起來都正常，但是當我嘗試運行該應用程序時，我在gradle控制檯中輸入了錯誤消息，您可以在帖子末尾看到該錯誤消息。對於我而言，錯誤消息很明顯，有些庫在內部使用了一些在我的依賴項之間常見的庫，它們可能有不同的版本。有人知道我該如何發現哪些庫存在衝突，以及如何解決這個問題（我無法從項目中刪除任何庫）。下面你可以在我的項目中找到構建文件的抽象。感謝提前:)

項目的gradle這個文件：

buildscript { 
    repositories { 
     mavenCentral() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:1.0.0' 
    } 
} 

allprojects { 
    repositories { 
     jcenter() 
    } 
} 

應用程序的（主模塊）gradle這個文件

buildscript { 
    repositories { 
    maven { url 'http://download.crashlytics.com/maven' } 
    } 

    dependencies { 
    classpath 'com.crashlytics.tools.gradle:crashlytics-gradle:1.+' 
    } 
} 
apply plugin: 'com.android.application' 
apply plugin: 'crashlytics' 

repositories { 
    mavenCentral() 
    maven { url 'http://download.crashlytics.com/maven' } 
} 

android { 
    compileSdkVersion 19 
    buildToolsVersion '19.1.0' 
    defaultConfig { 
    applicationId 'com.myapp' 
    minSdkVersion 16 
    targetSdkVersion 19 
    versionCode 1 
    versionName '1.0.0' 
    } 
    buildTypes { 
    debug { 
     debuggable true 
    } 
    release { 
     debuggable false 
    } 
    } 
    dexOptions { 
    preDexLibraries = false 
    } 
    lintOptions { 
    checkReleaseBuilds false 
    abortOnError false 
    } 
} 

dependencies { 
    compile project(':facebook') 
    compile 'com.crashlytics.android:crashlytics:1.+' 
    compile 'com.jakewharton:butterknife:6.0.0'

    compile 'com.squareup.okhttp:okhttp-urlconnection:1.6.0' 
    compile 'com.path:android-priority-jobqueue:1.1.2' 

    compile 'com.google.android.gms:play-services-base:6.5.87' // Analytics, GCM 
    compile 'com.google.android.gms:play-services-maps:6.5.87' 
    compile 'com.google.android.gms:play-services-location:6.5.87' 
    compile 'com.android.support:support-v13:21.0.0' 
}
