Java FireBase与Android Studio同步失败

我尝试实现一个应用程序，将您的详细信息放入Firebase的数据库中

我从网站同步代码 Android Studio版本：3.0.1 代码来自

build.gradle：

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

buildscript {
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'

        //you need to add this line
        classpath 'com.google.gms:google-services:3.2.0' // google-services plugin
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com" // Google's Maven repository
        }
    }
}

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

应用程序中的build.gradle：

 apply plugin: 'com.android.application'
android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.example.eranp.clientpage"
        minSdkVersion 19
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
    implementation files('libs/activation.jar')
    implementation files('libs/additionnal.jar')
    implementation files('libs/mail.jar')
    compile 'com.google.firebase:firebase-auth:11.8.0'
}


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

错误输出：

我需要做些什么来解决这个问题？

首先删除应用插件后的}符号。它不需要牙套。然后trydependencies{implementation fileTree（dir:'libs'，include:['*.jar']）实现'com.android.support.constraint:constraint布局：1.0.2'implementation'com.google.firebase:firebase auth:11.8.0'testImplementation'junit:junit:4.12'androidTestImplementation'com.android.support.test:runner:1.0.1'androidTestImplementation（'com.android.support.test.espresso:espresso core:3.0.1'））{exclude group:'com.android.support'，module:'support annotations'}}apply plugin:'com.google.gms.google-services'我完全无法重现此错误。是否有未显示的内容？请尝试一个新的、新的项目。这是一个新项目显示您的完全依赖关系
