Google App Engine - Download the entire live application to your local

Question

I recently upload a web app in my local app on Google App Engine

c:\LocalProject>c:\appengine-java-sdk-1.2.2\bin\appcfg.cmd update . 

Unfortunately, I accidentally delete the entire "LocalProject" folder on my local drive. Is it possible that I can recover all my stuff by downloading from the Google App Engine?

Answer 1

Not. There are libraries that you can include in the application to download the source code, but if you did not do this when you downloaded the application, there is no way to download the source code.

Answer 2

The app engine actually recently added the ability of the developer to download this version of the application to download the source code:

Answer 3

That's what source control systems like Subversion and Git are for. You should use it, even for your home projects.
