Setting Up Your Development Environment

To set up your environment for developing on Java 11:

Download and install the latest release of Java 11.

See Java 11 Runtime Environment for a list of the supported versions.
Download, install, and then initialize the Cloud SDK. If you already have the Cloud SDK installed, run the gcloud components update command to update to the latest release.

The Cloud SDK provides you the gcloud command-line tooling for deploying and managing your apps.

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

Run the following command in your terminal to install the gcloud component that includes the App Engine extension for Java 11:
```
 gcloud components install app-engine-java
```
