If you already have Java, Ant, Maven and the Java App Engine SDK installed, simply execute the following command in your console:

mvn archetype:generate -DarchetypeCatalog=http://mvn.withwaves.com

After entering the values for your project, you will have a running Google Wave robot & gadget ready in no time.

Use the same command to generate extensions in the future and you will have the option to enable new features as we release more extension generators.

Check out the videos below for a demo creating a simple "Hello World" robot and gadget, and optionally running it inside Eclipse and the Google Plugin for Eclipse.

When you create your Google Wave extension with our generator this is what you get…

• Runnable Hello World project ready to be modified and added to a Wave
• Spring integration in your robot / gadget back-end project compatible with Google App Engine
• Ant tasks to test your gadget locally and deploy to App Engine from the command line

• Gadget server handlers for communication from your gadget to the server with JSON / Spring
• jQuery integration for your gadgets
• Common gadget JS classes to handle Wave callbacks and state modifications
• Simple Wave JS emulator that allows you to view your gadget locally for testing HTML/JS/CSS before deploying
• Locale based language support for your gadget
• Metadata to expose your robot / gadget as a extension installer
