为什么 gradle 插件 3.3.0 不想构建谷歌服务？

Question

我正在尝试将我的项目与gradle:3.3.0同步，但在结果文件中，谷歌服务的values.xml未在文件夹：D:Androidworkspacemyprojectappbuildgeneratedresgoogle-servicesdebugvaluesvalues.xml中生成

顶级构建文件 build.gradle：

 apply plugin: 'kotlin'
    buildscript {
        ext.kotlin_version = '1.3.11'
        repositories {
            google()
            jcenter()
        }
        dependencies {
            classpath 'com.android.tools.build:gradle:3.3.0'
            classpath 'com.google.gms:google-services:4.1.0'
            classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
          }
    }
    allprojects {
        repositories {
            mavenLocal()
            google()
            jcenter()
            mavenCentral()
            maven { url "https://jitpack.io" }
        }
        configurations.all {
            exclude group: 'org.jetbrains.kotlin', module: 'kotlin-stdlib-jre7'
        }
    }
    dependencies {
        implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    }
    compileKotlin {
        kotlinOptions {
            jvmTarget = "1.8"
        }
    }
    compileTestKotlin {
        kotlinOptions {
            jvmTarget = "1.8"
        }
    }

app/build.gradle：

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'
android {
    ...
}
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "com.google.firebase:firebase-database:16.0.5"
implementation "com.google.firebase:firebase-messaging:17.3.4"
implementation "com.google.firebase:firebase-auth:16.1.0"
implementation 'com.google.android.gms:play-services-auth:16.0.1'
implementation 'com.google.firebase:firebase-storage:16.0.5'
}
apply plugin: 'com.google.gms.google-services'

google-services.json

文件google-services.json位于D:Androidworkspacemyprojectappgoogle-services.json

在运行应用程序后的结果中，发生错误：

 01-23 10:31:31.578 30044-30073/E/FA: GoogleService failed to initialize, status: 10, Missing google app id value from from string resources with name google_app_id.

从顶级 gradle 文件中删除依赖项块：

dependencies {
        implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    }

并更新到classpath 'com.android.tools.build:gradle:3.3.0'和classpath 'com.google.gms:google-services:4.2.0'因此，您的 Gradle 文件应该是这样的 Android Studio 3.3（稳定频道）

build.gradle（project：yourProject）

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    ext.kotlin_version = '1.3.11'
    repositories {
        google()
        jcenter()
        // Add repository
        maven {
            url 'https://maven.fabric.io/public'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.2.0'
        classpath 'io.fabric.tools:gradle:1.26.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        google()
        jcenter()
        // Add repository
        maven {
            url 'https://maven.google.com/'
        }
    }
}
task clean(type: Delete) {
    delete rootProject.buildDir
}
