Question

我正在使用 Firebase 创建 Facebook 登录 系统。但是当我编译项目时，它给了我：

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'. com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/android/gms/common/api/zze.class

build.gradle（项目）：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'
        classpath 'com.google.gms:google-services:3.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

build.gradle（应用）：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "24.0.2"
    defaultConfig {
        applicationId "com.zihadrizkyef.belajar_facebooklogin"
        minSdkVersion 19
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:multidex:1.0.1'
    compile 'com.android.support:appcompat-v7:25.0.1'
    compile 'com.google.firebase:firebase-core:10.0.0'
    compile 'com.google.firebase:firebase-auth:9.8.0'
    compile 'com.facebook.android:facebook-android-sdk:[4,5)'
    testCompile 'junit:junit:4.12'
}

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

在我的项目中，不同的 jar 或 lib 中有一些重复的文件，我在我的应用程序中添加了一些代码 build.gradle，如下所示：

packagingOptions {
    exclude 'META-INF/DEPENDENCIES.txt'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INFTICE.txt'
    exclude 'META-INFTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INFtice.txt'
    exclude 'META-INFcense.txt'
    exclude 'META-INF/dependencies.txt'
    exclude 'META-INF/LGPL2.1'
    exclude 'META-INF/MANIFEST.MF'
    exclude 'META-INF/maven/com.google.protobuf/protobuf-java/pom.xml'
    exclude 'META-INF/maven/com.google.protobuf/protobuf-java/pom.properties'
}

而且有效。

我想你可能会包括一些其他的罐子，其中包括 "com/google/android/gms/common/api/zze.class" 或整个罐子。

UMeng jars 包含 protobuf，我的模型也包含，所以我在 packagingOptions.build.gradle 中排除了两个 protobuf-java 文件。

Answer 2

所有 Firebase 库必须是同一版本。使用 firebase-auth:

的 10.0.0 版本

compile 'com.google.firebase:firebase-core:10.0.0'
compile 'com.google.firebase:firebase-auth:10.0.0'

Answer 3

compile 'com.android.support:appcompat-v7:25.0.1'
compile 'com.google.firebase:firebase-core:10.0.0'
compile ('com.google.firebase:firebase-auth:9.8.0') {
    exclude group: 'com.google.android.gms'
}
compile 'com.facebook.android:facebook-android-sdk:4.+'
compile 'com.android.support:multidex:1.0.1'
testCompile 'junit:junit:4.12'
