Tidak dapat menemukan com.google.gms:google-services:3.1.1

Saya mendapatkan pengecualian:

Could not find com.google.gms:google-services:3.1.1. 

ketika saya memulai proyek Android saya.

Build.gradle saya (Proyek: Android)

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

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.1'

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

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
        google()
    }
}

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

dan build.gradle (Modul: aplikasi)

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion '26.0.2'
    defaultConfig {
        applicationId "de.derdoenerdon.ressourcencockpit"
        minSdkVersion 15
        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 {
    implementation 'com.android.support:support-v4:25.4.0'
    implementation 'com.android.support:recyclerview-v7:25.4.0'
    implementation 'com.android.support:design:25.4.0'


    implementation 'com.google.firebase:firebase-storage:11.8.0'
    implementation 'com.google.firebase:firebase-auth:11.8.0'
    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'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.android.support:design:25.4.0'


    compile 'com.github.OPCFoundation:UA-Java:1.03.342.0'


    testCompile 'junit:junit:4.12'
    testCompile group: 'org.slf4j', name: 'slf4j-simple', version: '1.7.7'

}

buildscript {
    dependencies {
        classpath 'com.google.gms:google-services:3.1.1'
    }
}
apply plugin: 'com.google.gms.google-services'

Tentang bantuan apa pun, saya akan sangat berterima kasih. Saya baru di android. Itu terjadi, karena saya mencoba menggunakan firebase di aplikasi saya dan itu menambahkan beberapa ketergantungan pada aplikasi saya secara otomatis. Terima kasih banyak

EDIT: Beginilah tampilan gradle.build (Modul: app) saya sekarang:

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion '27.0.3'
    defaultConfig {
        applicationId "de.derdoenerdon.ressourcencockpit"
        minSdkVersion 15
        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 {
    implementation 'com.android.support:support-v4:25.4.0'
    implementation 'com.android.support:recyclerview-v7:25.4.0'
    implementation 'com.android.support:design:25.4.0'


    implementation 'com.google.firebase:firebase-storage:11.8.0'
    implementation 'com.google.firebase:firebase-auth:11.8.0'
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation 'com.android.support:appcompat-v7:25.3.1'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation 'com.android.support:design:25.4.0'


    implementation 'com.github.OPCFoundation:UA-Java:1.03.342.0'


    testImplementation 'junit:junit:4.12'
    testImplementation group: 'org.slf4j', name: 'slf4j-simple', version: '1.7.7'

}


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

dan ini peringatan yang saya dapatkan sebagai output:

Configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'.
It will be removed at the end of 2018. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html 

Adakah yang tahu cara menghilangkan peringatan ini? Terima kasih
