Setting Up Your Development Environment

To develop and deploy Java apps on App Engine, you need to download and install Java and Cloud SDK.

Installing Java and Cloud SDK

1. Download and install Java 11:

   Download and install Java

   Important: The Java runtime in the App Engine standard environment uses the latest release of Java version 11. To avoid errors, ensure you have the same version installed on your machine. For more information about the Java runtime, see Java Runtime Environment.

2. Download, install, and initialize Cloud SDK, which provides the gcloud command-line tool:

   Download and install Cloud SDK

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

Installing optional tools

• Install Java 11 tools. You can use the Maven or Gradle plugins to build, deploy, and manage your Java 11 apps:

  • Apache Maven and the App Engine Plugin
  • Gradle and the App Engine Plugin

• Install an IDE or editor to develop Java apps. Popular editors include:

  • Eclipse by Eclipse Foundation
  • IntelliJ IDEA and/or Webstorm by JetBrains
  • Atom by GitHub

  These editors (sometimes with the help of plugins) give you everything from syntax highlighting, intelli-sense, and code completion to fully integrated debugging capabilities.

• For access to helpful functions within your editor, check out the Google-sponsored plugins for Eclipse or IntelliJ.

• For access to code, samples, libraries, and tools in GitHub, install Git:
