This was a problem with jcenter servers redirecting to mavenCentral, even if the dependency didn’t exist in mavenCentral.
It’s supposedly fixed by now, so you can go back to your old version, despite I wouldn’t recommend it.
Your problem now is that whitelist plugin was deprecated and integrated into cordova-android and renamed to AllowList, so your filetransfer plugin is not finding those classes because they are not there anymore. The plugin was updated to use AllowList, but was never released.
You can install the plugin like cordova plugin add https://github.com/apache/cordova-plugin-file-transfer or npm install https://github.com/apache/cordova-plugin-file-transfer if using Capacitor
