This page describes how to deploy your project to the App Engine flexible environment using a WAR archive or a runnable JAR file.

You need a Google Cloud project with an App Engine application to deploy to. If you don't already have one, use the Google Cloud Console to set up your Cloud project:
- Select or create a new Cloud project.
Sign in to a Google account that is used to deploy your project to App Engine.
Select File > Sign in to Google.

Click Allow and close the window. Eclipse is now signed into your account.

If you want to keep the current version running and manually promote the new version later using gcloud or the Google Cloud Console, clear the Promote the deployed version to receive all traffic checkbox.
If you don't want to stop the previous version, clear the Stop previous version checkbox.
After a successful deployment, Eclipse opens an internal browser connecting to the deployed app.
