Answer 1

I finally made it to work, I was missing the name of the app in my case "backend" the command was

gradlew :backend:appengineUpdate

Answer 2

Android Studio itself showed a red X over my backend project, I followed what BradR said and terminal prompted that gradlew did not exist as a command, so if that doesn't work for you, then try this:

./gradlew :backendName:appengineRun
