According to the page below, there are Eclipse project files included with the source; apparently that is incorrect. So is the documentation wrong, or did somebody forget to include the .project files?
>From http://cloudstack.apache.org/develop/environment.html: Getting Source CloudStack uses git for source version control, if you know little about git, http://book.git-scm.com/ is a good start. Once you have git setup on your machine, pull source with: git clone https://git-wip-us.apache.org/repos/asf/cloudstack.git Importing Source into Eclipse Most Apache CloudStack developers use Eclipse as their primary IDE. CloudStack source code already includes Eclipse .project file in each project folder, you can import them to your Eclipse workspace by: - Creating a new Eclipse workspace, right clicking package explorer and selecting *Import*. - Selecting *"Existing Projects into Workspace"*. - Browsing to the folder with CloudStack source code. - Click *Open*, where you will see all Apache CloudStack projects listed in the dialog box. Click the *Finish* button. Now you have CloudStack registered with Eclipse.
