I tried removing and adding the platform, also removing and adding the node_modules but still get the same error. My Cordova version is 8.0 . anybody knows how to solve this?

Answer 1

在根目录（不是平台目录）中创建了 Android 文件夹，删除此文件夹后，命令再次运行。

Answer 2

从项目目录中删除 Android 文件夹

Answer 3

重命名该文件夹后，根目录 （而非platforms目录）中存在一个Android文件夹，该命令再次生效。就像您重命名android2一样，因为它是您的备份。

Answer 4

I accidentiall run the capacitor command instead of using cordova. After removing the android forlder that was created with the capacitor command it worked again.
