android - 将 firebase 依赖项添加到 Android 应用程序时应用脚本 build.gradle 错误

Question

我正在将 firebase 添加到我的 android 应用程序中。添加依赖项 classpath 'com.google.gms:google-services:4.3.0' 和实现 'com.google.firebase:firebase-database:18.0.1' 之后和应用 plugin: 'com.google.gms.google-services' 的插件并尝试同步它会带来“Apply script build.gradle”错误

我已经更新了我的谷歌存储库并且有良好的互联网连接

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

dependencies {
        classpath 'com.android.tools.build:gradle:4.2.1'
        classpath 'com.google.gms:google-services:4.3.0'}`
dependencies{implementation 'com.google.firebase:firebase-database:18.0.1'}

我希望在添加依赖项和应用插件后同步成功，但发生错误

检查 the doc:

要设置 firebase，您必须配置 top-level build.gradle 文件:

buildscript {

  repositories {
    // Check that you have the following line (if not, add it):
    google()  // Google's Maven repository
  }

  dependencies {
    // ...

    // Add the following line:
    classpath 'com.google.gms:google-services:4.3.0'  // Google Services plugin
  }
}

allprojects {
  // ...

  repositories {
    // Check that you have the following line (if not, add it):
    google()  // Google's Maven repository
    // ...
  }
}

然后在你的 app/build.gradle 中:

apply plugin: 'com.android.application'

android {
  // ...
}

dependencies {
  // ...
  implementation 'com.google.firebase:firebase-database:18.0.1'

}

// Add the following line to the bottom of the file:
apply plugin: 'com.google.gms.google-services'  // Google Play services Gradle plugin

完成setup of the google play services plugin你必须

• 添加 google-services.json 文件。
