关于android：与firebase 11.8.0 和google-services 插件3.1.2 冲突

Conflict with firebase 11.8.0 and google-services plugin 3.1.2

我与 firebase 11.8.0 和 google-services 插件 3.1.2 存在明显冲突。构建失败，建议我改用 11.4.2 版的 firebase。

我的 gradle 构建文件的相关摘录：

根 build.gradle

buildscript {
repositories {
google()
...
}
dependencies {
classpath 'com.google.gms:google-services:3.1.2'
...
}
}

应用程序 build.gradle:

apply plugin: 'com.google.gms.google-services'
repositories {
google()
....
}
dependencies {
implementation"com.google.firebase:firebase-core:11.8.0"
....
}

我已经正确生成了 firebase 应用文件：

1 2	./app/src/debug/google-services.json ./app/src/release/google-services.json

当我使用 ./gradlew clean assembleDebug 构建时，构建失败并出现以下错误：

> Task :app:processDebugGoogleServices FAILED
Found com.google.firebase:firebase-core:11.8.0, but version 11.4.2 is needed for the google-services plugin.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugGoogleServices'.
> Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 11.4.2.

解决方法是将此行移到应用程序 build.gradle 文件的底部(它不应该在顶部)：

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

这是在文档中指定的：

https://firebase.google.com/docs/android/setup

Then, in your module Gradle file (usually the app/build.gradle), add
the apply plugin line at the bottom of the file to enable the Gradle
plugin:

apply plugin: 'com.android.application'

android {

}

dependencies {
// ...
compile 'com.google.firebase:firebase-core:11.8.0'

// Getting a"Could not find" error? Make sure you have
// added the Google maven respository to your root build.gradle
}

// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'
