在我的 ionic 项目中，执行起来没有问题：
ionic cordova platform add android
但在那之后我尝试运行：
ionic cordova build android --prod --release
我收到以下错误：
Total time: 2.535 secs
Error:

似乎对讲机正在尝试在 intercom.gradle 添加一个插件：
if (pushType == 'fcm') {
tasks.copyGoogleServices.execute()
apply plugin: com.google.gms.googleservices.GoogleServicesPlugin
}
并尝试从带有 + 的版本中添加一些属性。
下面我添加我的 package.json 来帮助你，我读到 google-services 版本存在一些问题，我设置了我所有的 google-services:3.0.0 版本。但还是崩溃。
