I noticed that the builds on our CI started to fail because of the following error:
Discovered plugin \"cordova-plugin-app-version\" in config.xml. Adding it
I also get this error after updating to 9.0.0. In my case I fixed it doing a clean up and rebuilding my app. You can try the following steps.
npm install -g cordova./android/tools/bin/sdkmanager "build-tools;28.0.3" "platforms;android-28"export ANDROID_SDK_ROOT=~/android(1) ANDROID_HOME is deprecated but still working
cordova platform add androidcordova plugin add cordova-plugin-whitelistcordova buildYou can check a resume of your app with: cordova info
If you want to see a list of your plugin you can use: cordova plugins ls
Hope this help or at least point someone to the right direction :)
