android - Gradle 未针对 Firebase 云消息传递进行编译

Question

我注意到 Firebase API 已从 v 9.0.0 升级到 v 9.0.1，因此决定对其进行更改。

然而它并没有引起注意。

这是 Gradle Logcat 中的错误

   Error:(25, 13) Failed to resolve: com.google.firebase:firebase-messaging:9.0.1
   Error:(26, 13) Failed to resolve: com.google.firebase:firebase-core:9.0.1

这是我的 Gradle 文件

Build.Gradle->应用

  apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.3"

defaultConfig {
    applicationId "com.example.lifeline.applicationgreat"
    minSdkVersion 15
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

 dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.google.firebase:firebase-messaging:9.0.1'
compile 'com.google.firebase:firebase-core:9.0.1'
}

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

Build.Gradle->项目

     // 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:2.1.0'
    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 
}

谁能告诉我错误是什么，或者我是否遗漏了什么。另外，云消息传递对 Firebase-core 有什么要求吗？谢谢
