Running and Debugging an App Engine Standard Project locally Inside Eclipse

This page shows you how to run and debug your App Engine standard project in an emulator running on your local computer.

Cloud Tools for Eclipse uses the Eclipse Web Tools Project flow.

Running the project locally

  1. Select the project in the Project Explorer or Package Explorer.
  2. Open the context menu.
  3. Select Run As > App Engine.

  4. Log messages appear in the console as the server starts up.

  5. Eclipse opens its internal web browser to your application. You can also open an external browser and navigate to http://localhost:8080. Either way, you'll see a static HTML page with a link to the servlet.

    Available Servlets: The servlet

Debugging the project locally

To debug your project locally, complete the running the project locally steps, except select Debug As > App Engine instead of Run As > App Engine in the context menu.

The server stops at the breakpoints you set and shows the Eclipse debugger view.
