错误警告：应避免使用 flatDirs，因为它不支持任何元数据格式

Question

我的 Ionic/Angular 项目运行ning 在 Android 上遇到问题。尝试通过全新安装的 Node、Angular、Ionic、Android studio、Ionic 的新项目（选项卡）来解决问题。

还是不会运行我已经坚持了两天了。我现在收到以下错误。

我看到的问题是它引用的 capacitor-cordova-android-plugins 文件夹在每次构建时都会重建，尽管 root build.gradle 和 app build.gradle 已经有了进行了错误中列出的更改。真让我抓狂。

感谢帮助！

我目前正在做一个 ionic/Angular 项目，我犯了和你一样的错误。我做了什么：

关闭 Android 工作室。
从我的项目中删除 android 和 ios 文件夹
构建 (ionic build)。
npx cap add ios
npx cap add android
npx cap update
重新启动 Android Studio
