Creating an application in the App Engine flexible environment

Note: Cloud Tools for Eclipse is only compatible with the App Engine Java 8 runtime, which will reach the end of support on January 31, 2024. After this date, your existing Java 8 applications will continue to run and receive traffic. However, you cannot deploy new or update existing applications that use runtimes after their end of support date. We recommend that you migrate to the latest supported version of Java.

Cloud Tools for Eclipse provides a wizard inside Eclipse to create new applications for the App Engine flexible environment.

Before you begin

1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

2. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

   Go to project selector

3. Make sure that billing is enabled for your Google Cloud project.

4. Enable the Cloud Build API.

   Enable the API

5. Install the Google Cloud CLI.

6. To initialize the gcloud CLI, run the following command:

   gcloud init

7. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

10. Install the Google Cloud CLI.

11. To initialize the gcloud CLI, run the following command:

    gcloud init

12. Create an App Engine application for your Google Cloud project in the Google Cloud console.

    Open app creation

13. Select a region where you want your app's computing resources located.

    Note: After you create your App Engine app, you cannot change the region. To reduce latency, choose the region closest to your app's intended users. For more information on the available regions, see App Engine Locations.
14. Ensure you have the latest version of Cloud Tools for Eclipse.
