Gradle sync failed: Plugin with id 'com.google.android.gms:play-services' not found

Question

In one of my projects I need to use GoogleMaps and Firebase for notifications but the libraries of the service and the Firebase in place do not want to work.

buildscript {
    repositories {
        google()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
    dependencies {
        classpath 'com.google.android.gms:play-services:8.4.0'
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

repositories {
    maven { url 'https://maven.fabric.io/public' }
    maven { url "https://maven.google.com" }
}

android {
    compileSdkVersion 26
    buildToolsVersion '26.0.2'
    defaultConfig {
        applicationId "com.online.app"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 8
        versionName "2.5"
        multiDexEnabled true
    }
    buildTypes {
        release {
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }    
    productFlavors {
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:support-v4:26.0.2'
