Android工作室2.3.2 gradle錯誤，同時使用firebase

Question

我使用的是我的android studio應用程序的firebase。不過，我被困在這個問題上，我已經盡了一切辦法來弄清楚，但我無法做到。請幫忙。

這是錯誤：

Gradle sync failed: Could not find method classpath() for arguments [com.android.tools.build:gradle:2.3.3] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

頂級gradle.build代碼

buildscript { 
      repositories { 
       jcenter() 
      } 
      dependencies { 
       classpath 'com.android.tools.build:gradle:2.3.3' 
       classpath 'com.google.gms:google-services:3.1.0' 
      } 
     } 

     allprojects { 
      repositories { 
       jcenter() 
      } 
     } 

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

其他gradle這個代碼：

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 25 
    buildToolsVersion "25.0.2" 
    defaultConfig { 
     applicationId "com.mobility.mobilityindia" 
     minSdkVersion 21 
     targetSdkVersion 25 
     versionCode 1 
     versionName "1.0" 
     testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

dependencies { 
    classpath 'com.android.tools.build:gradle:2.3.3' 
    classpath 'com.google.gms:google-services:3.1.0' 
    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' 
    }) 
    String googleSupportVersion = '25.3.1' 
    String googlePlayServicesVersion = '11.0.2' 

    compile "com.google.firebase:firebase-core:$googlePlayServicesVersion" 
    compile "com.google.firebase:firebase-auth:$googlePlayServicesVersion" 
    compile "com.android.support:appcompat-v7:$googleSupportVersion" 
    compile "com.android.support:support-v4:$googleSupportVersion" 
    compile "com.google.android.gms:play-services:$googlePlayServicesVersion" 
    compile "com.android.support:design:$googleSupportVersion" 
    compile 'com.android.support.constraint:constraint-layout:1.0.2' 



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

從Android級build.gradle刪除這兩個文件

dependencies { 
    classpath 'com.android.tools.build:gradle:2.3.3' <-- 1. 
    classpath 'com.google.gms:google-services:3.1.0' <-- 2. 
    ... 
    ... 

}
