Ionic Build Android - build.gradle文件不断添加重复的编译行并导致构建失败 _android

亦余心之所善兮，虽九死其犹未悔。这篇文章主要讲述Ionic Build Android - build.gradle文件不断添加重复的编译行并导致构建失败相关的知识，希望能为你提供帮助。
在我的Ionic 3项目中，我跟着this guide看看我是否可以让我的android项目进行编译，但是无论何时我尝试运行ionic cordova build android，我都会收到此错误：

* What went wrong: A problem occurred configuring root project 'android'. > Cannot add task ':processDebugGoogleServices' as a task with that name already exists.

我不确定这是否是FCM的一个问题，但我注意到，无论何时运行build命令，此行都显示在我的build.gradle文件中
compile "com.google.firebase:firebase-messaging:9.0.2"- 我随时删除它，它会一直显示我的其余编译语句，如下所示：

dependencies { compile fileTree(dir: 'libs', include: '*.jar') // SUB-PROJECT DEPENDENCIES START debugCompile(project(path: "CordovaLib", configuration: "debug")) releaseCompile(project(path: "CordovaLib", configuration: "release")) compile "com.google.android.gms:play-services-base:+" compile "com.google.android.gms:play-services-ads:+" compile "com.android.support:support-v4:24.1.1+" compile "com.facebook.android:facebook-android-sdk:4.+" compile "com.google.firebase:firebase-core:+" compile "com.google.firebase:firebase-messaging:+" compile "com.android.support:support-v4:25.+" compile "com.android.support:appcompat-v7:25.+" compile "com.squareup.okhttp3:okhttp:3+" compile "com.android.support:appcompat-v7:23.2.1" compile "com.google.firebase:firebase-messaging:9.0.2" // SUB-PROJECT DEPENDENCIES END } apply plugin: 'com.google.gms.google-services'

另外，这是我的config.xml供参考：

这是我在project.properties的/platforms/android文件

【Ionic Build Android - build.gradle文件不断添加重复的编译行并导致构建失败】有谁知道这里发生了什么？
答案似乎FCM gradle试图应用插件，这可能已经在你的build.gradle文件中应用了。
请按照以下说明操作。

In FCM Gradle, comment the last line (below) that contains Googleservicesplugin

“平台机器人科尔多瓦 - 插件-FCMyour_app-FCMPlugin.gradle”

buildscript { repositories { jcenter() mavenLocal() } dependencies { classpath 'com.android.tools.build:gradle:+' classpath 'com.google.gms:google-services:3.0.0' } } // apply plugin: 'com.google.gms.google-services' < ---- COMMENT THIS LINE TOO, add to Root gradle file // class must be used instead of id(string) to be able to apply plugin from non-root gradle file //apply plugin: com.google.gms.googleservices.GoogleServicesPlugin < ---- COMMENT THIS LINE
