android - 添加 ML Kit 后无法解析 : com. google.android.gms :play-services:15. 0.1

Question

Look here 请我尝试将 ML Kit 添加到我的应用程序的构建 gradle，但它没有完全运行。我想它一定来 self 的 build.gradle 文件，但我不知道在哪里。请帮忙？

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.1.1'

    //Firebase libraries
    implementation 'com.google.firebase:firebase-auth:16.0.2'
    implementation 'com.google.firebase:firebase-database:16.0.1'
    implementation 'com.google.firebase:firebase-storage:16.0.1'
    implementation 'com.google.firebase:firebase-messaging:17.1.0'
    implementation 'com.google.firebase:firebase-core:16.0.1'
    implementation 'com.google.android.gms:play-services-ads:15.0.1'
    implementation 'com.google.firebase:firebase-ads:15.0.1'
    implementation 'com.google.firebase:firebase-ml-vision:16.0.0'

    //Other Stuff
    implementation 'com.firebase:geofire-android:2.3.0'
    implementation 'com.android.support:support-vector-drawable:27.1.1'
    implementation 'com.android.support:support-v4:27.1.1'
    implementation 'com.android.support:design:27.1.1'
    implementation 'com.android.support:cardview-v7:27.1.1'
    implementation 'com.android.support:recyclerview-v7:27.1.1'
    implementation 'com.android.support:support-v13:27.1.1'
    implementation 'com.r0adkll:slidableactivity:2.0.6'
    implementation 'de.hdodenhof:circleimageview:2.2.0'
    implementation 'com.google.android.gms:play-services-maps:15.0.1'
    implementation 'com.android.support:multidex:1.0.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.android.support:support-annotations:27.1.1'
    implementation 'com.google.android.gms:play-services:15.0.1'
}

下面是build.gradle(project)。我什至包括了谷歌存储库，但仍然无济于事。请帮忙

    buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0-alpha03'

        classpath 'com.google.gms:google-services:4.0.2'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven{
            url 'https://maven.google.com'
        }
    }
}

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

Google API Release Notes表示对合并的 play-services 库的支持已于 2018 年 4 月结束:

Starting with 15.0.0, there will no longer be a play-services alias target to pull in all Google Play services components. This has been recommended against for some time.

您不能再指定对组合 Google Play 服务目标的依赖，implementation 'com.google.android.gms:play-services:15.0.1'。当以前的版本支持它时，它会引入所有 Google Play 库——远远超过您的需要。请参阅 Setup Guide 的表 1 中的 API 列表并仅包含您的应用使用的特定内容。

检查 Google Maven Repository确认版本 12.0.1 是组合播放服务目标的最后一个版本。
