Android 添加com.google.gms.google-services时gradle中的版本冲突

我使用助手将firebase云消息添加到我的项目中，在android studio构建项目时遇到以下错误消息：

错误：任务“：app:processDebugGoogleServices”的执行失败。 请通过更新的版本来修复版本冲突 谷歌服务插件（关于最新版本的信息 可在 ) 或者将com.google.android.gms的版本更新为9.8.0

以下是生成文件：

顶级：

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

buildscript {  
    repositories {  
        jcenter()  
    }  
    dependencies {  
        classpath 'com.android.tools.build:gradle:2.3.0'  

        // NOTE: Do not place your application dependencies here; they belong  
        // in the individual module build.gradle files  
        classpath 'com.google.gms:google-services:3.0.0'  
    }  
}  

allprojects {  
    repositories {  
        jcenter()  
    }  
}  

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

compile 'com.google.android.gms:play-services:10.0.0'
compile 'com.google.firebase:firebase-messaging:10.0.1'
