为什么 gradle 插件 3.3.0 不想构建 google-服务？

Question

我正在尝试 Sync 我的项目与 gradle:3.3.0 ，但在结果文件 values.xml 中未生成 google-services在文件夹中：D:\Android\workspace\myproject\app\build\generated\res\google-services\debug\values\values.xml

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:\Android\workspace\myproject\app\google-services.json

应用运行后的结果出现错误：

 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.

Answer 1

在项目级别 build.gradle 中更新到 classpath 'com.google.gms:google-services:4.2.0'。

Answer 2

从顶级 gradle 文件中删除依赖块：

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

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

build.gradle(项目:你的项目)

// 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
}
