Notice: Over the next few months, we're reorganizing the App Engine documentation site to make it easier to find content and better align with the rest of Google Cloud products. The same content will be available, but the navigation will now match the rest of the Cloud products.

Setting Up Your Development Environment

To set up your environment for developing on Java 8:

  1. Install the latest release of Java 8.

    See Java 8 Runtime Environment for a list of the supported versions.

  2. Install and initialize the gcloud CLI for deploying and managing your apps. If you already have the gcloud CLI installed and initialized, run the gcloud components update command to update to the latest release.

    By downloading, you agree to be bound by the Terms that govern use of the gcloud CLI for App Engine.

  3. Install the gcloud component that includes the App Engine extension for Java 8.

    If you used the apt or yum package managers to install the gcloud CLI, use those same package managers to install the gcloud component.

    Otherwise, use the following command:

     gcloud components install app-engine-java
    

Installing optional tools

Give permission to Cloud Build

When you deploy your app, App Engine uses Cloud Build to build the app into a container and deploy the container to the runtime. Cloud Build does not have permission to deploy Java 8 apps by default, so you need to give Cloud Build permission to deploy apps in your project. The builds are created in the app's region.
