Java – How to Download Existing Google App Engine Project

This article represents tips on how to download existing google app engine project including its source code (HTML/JSP files).. Please feel free to comment/suggest if I missed to mention one or more important points. Also, sorry for the typos.

Following are steps that need to be taken:

Make sure you have JDK installed. Access this page for downloading Java
Download Google App Engine SDK for Java. The download file could be found on this page.
Unzip the App engine SDK and go to the bin folder using command prompt.
Go to your http://appengine.google.com account and get the information such as your app_name and your_app_version.

On Windows, execute the command as shown below:

<path to appengine-java-sdk>\bin\appcfg.cmd -A <your_app_id>; -V <your_app_version> download_app <output-dir>

On linux, execute following command:

./appengine-java-sdk/bin/appcfg.sh -A <your_app_id>; -V <your_app_version> download_app <output-dir>

That is it. Above would open the browser asking you the permission to download and sharing you a code which you would copy and paste at the command prompt.
