我刚刚更新到Android Studio 3.3，并尝试将Gradle插件更新到3.3.0，但是项目构建失败。
该项目是一个带有应用程序的库（使用该库）。尝试了所有操作：清除，重建，重置，删除.gradle目录，甚至重新启动计算机都没有运气。有想法吗？
这是堆栈跟踪

我只是在尝试其他方法时找到了解决方案。 由于某种原因，我在库的gradle文件中安装了Google Services插件，因此我将其删除，并且该项目的构建没有问题。
我删除了这一行
apply plugin: 'com.google.gms.google-services'

在项目级别build.gradle中更新Google Play服务类路径
classpath 'com.google.gms:google-services:4.3.3'
