error duplicate entry: com/google/android/gms/common/api/zze.class

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'

android {
compileSdkVersion 25
buildToolsVersion "24.0.2"
defaultConfig {
applicationId "com.zihadrizkyef.belajar_facebooklogin"

androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {

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'

Answer

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'
