This sample shows how to deploy an application to Google App Engine from source. The entrypoint field listed in the app.yaml is not required,
as GAE will determine the entrypoint by searching the target directory for the .jar file with a Main-Class Manifest entry.
See Prerequisites.
gcloud app deploy
To view your app, use command:
gcloud app browse
Or navigate to https://<your-project-id>.appspot.com.
