You deployed an App Engine app but it deployed to the wrong project. How can you determine which Google Cloud configuration was used for the deployment?

The gcloud config list command displays the active configuration properties, including the project that gcloud commands will target by default. This is crucial for understanding which project a deployment command would have used. Checking app.yaml or web-application.xml (for Java apps) is incorrect because these files define application settings, not the target Google Cloud project. Deployment Manager is for managing infrastructure deployments, not for inspecting the gcloud CLI's active project configuration.
