Android Studio＆Gradle：多个dex文件

Question

今天我迁移到Android Studio 1.1并开始更新某些库的版本。当我使用gradle按钮构建项目时，一切看起来都正常，但是当我尝试运行该应用程序时，我在gradle控制台中输入了错误消息，您可以在帖子末尾看到该错误消息。对于我而言，错误消息很明显，有些库在内部使用了一些在我的依赖项之间常见的库，它们可能有不同的版本。有人知道我该如何发现哪些库存在冲突，以及如何解决这个问题（我无法从项目中删除任何库）。下面你可以在我的项目中找到构建文件的抽象。感谢提前:)

项目的gradle这个文件：

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

allprojects { 
    repositories { 
     jcenter() 
    } 
} 

应用程序的（主模块）gradle这个文件

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

    versionName '1.0.0' 
    } 
    buildTypes { 
    debug { 
     debuggable true 
    } 
    release { 
     debuggable false 
    } 
    } 
    dexOptions { 
    preDexLibraries = false 
    } 
    lintOptions { 
    checkReleaseBuilds false 
    abortOnError false 
    } 
}

    compile project(':facebook')

}
