I am creating Facebook login system with Firebase. But when I compile the project, it gives me:

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 (project):

// 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 (app):

apply plugin: 'com.android.application'

    buildToolsVersion "24.0.2"
    defaultConfig {

    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'
    

  2. In my project, there are some duplicate files in different jars or libs, I add some codes int my app build.gradle like this:

    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'
    }
    

    And it works.

    I think you may include some other jars that include “com/google/android/gms/common/api/zze.class” or whole jar.

    UMeng jars contains protobuf ,and my model contains too, so I exclude two protobuf-java file in build.gradle ,in packagingOptions.

  3. All the Firebase libraries must be the same version. Use version 10.0.0 of firebase-auth:

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