重复条目：添加 facebook sdk 后的 com/google/android/gms/internal/zzaa.class

Question

只有在添加 facebook Audience Network sdk 后尝试生成发布 apk 时才会出现此错误。

完全错误：任务“:app:transformClassesWithJarMergingForRelease”执行失败。 > com.android.build.api.transform.TransformException：java.util.zip.ZipException：重复条目：com/google/android/gms/internal/zzaa.class

这是 gradle 文件：

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

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

android {
    compileSdkVersion 24
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.coolcrazyapps.myapp"
        minSdkVersion 15
        targetSdkVersion 21
        versionCode 10
        versionName "2.0"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

repositories {
    mavenCentral()
    maven { url 'https://maven.fabric.io/public' }
}

dependencies {
    // Support Libraries
    // Misc Libraries
    compile fileTree(dir: 'libs')
    compile('com.crashlytics.sdk.android:crashlytics:2.5.2@aar') {
        transitive = true;
    }

    compile 'com.android.support:appcompat-v7:24.0.0'
    compile 'com.android.support:support-v13:24.0.0'
    compile 'com.android.support:support-v4:24.0.0'
    compile 'com.github.hotchemi:android-rate:0.4.1'
    compile('com.google.firebase:firebase-core:9.2.1')
    compile 'com.google.firebase:firebase-messaging:9.2.1'
    compile 'io.branch.sdk.android:library:1.+'
    compile 'com.android.support:design:24.0.0'
    compile('com.facebook.android:audience-network-sdk:4.13.0') {
        exclude group: 'com.google.firebase'
    }
}

apply plugin: 'com.google.gms.google-services'

这是./gradlew app:dependencies的输出

在 Android Studio 中，我在以下位置看到 zzaa 文件：
