无法解析 com.google.firebase:firebase-core:10.0.1

我想在我的 Android 应用程序中使用 Firebase 云消息传递。 这是我的应用程序级别 gradle 文件

apply plugin: 'com.android.application'
android {
    signingConfigs {
        config {
            keyAlias 'androiddebugkey'
            keyPassword 'android'
        }
        config1 {
            keyPassword 'android'
        }
    }
    compileSdkVersion 23
    buildToolsVersion "23.0.3"
    packagingOptions {
        exclude 'main/AndroidManifest.xml'
    }
    defaultConfig {
        applicationId "com.shikhar.dexter.project"
        minSdkVersion 19
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')

    compile 'com.google.firebase:firebase-messaging:10.0.1'

    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.android.support:design:23.4.0'
    compile 'com.android.support:cardview-v7:23.4.0'
    compile 'com.android.support:recyclerview-v7:23.4.0'
    compile 'com.android.support:support-v4:23.4.0'

    compile 'com.google.android.gms:play-services:9.0.0'
    compile 'com.google.android.gms:play-services-auth:9.0.0'

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

这是我的根级别 gradle 文件

   // 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:2.2.3'
        classpath 'com.google.gms:google-services:3.0.0'
        classpath 'com.android.tools.build:gradle:2.1.0'

        // NOTE: Do not place your application depndencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven{
            url  "http://dl.bintray.com/dasar/maven"
        }
    }
}

编译时显示以下错误：

Failed to resolve: com.google.firebase:firebase-core:10.0.1

Error:(36, 13) Failed to resolve: com.google.firebase:firebase-messaging:10.0.1

我尝试了各种 Google Play 服务版本，例如 9.4.0，但仍然不起作用。

打开 SDK 管理器并确保您已下载最新的“Google Play 服务”依赖项。
