有人能告诉我如何处理这个问题吗？非常感谢。

上面说复制的类被复制了。如何解决这个问题。我尝试在build.gradle中排除，但没有任何帮助。

我在构建应用程序时遇到了同样的问题，我通过

更新android SDK

使用适当的命令移除平台

爱奥尼亚cordova平台删除android

（如果您使用的是最新的CLI）

然后再次添加android平台并构建它

如果仍然不起作用，请尝试将nodejs降级到以前的版本并构建。

解决了这个问题。

我需要排除META-INF

更新您的android sdk，然后重建您的项目。在这种情况下，如何排除META-INF？更新配置文件？运行另一个离子命令？删除一些文件？
