How to create a Netbeans 7 project from an existing git repo?
Use the Team menu, select "Git" > "Clone..."
Once the repo has been cloned into a local folder, NetBeans will give you the option to open the project.
Trying to create a project and then clone into it fails because the target folder is not completely empty.
Just clone the repo into your (newly created) netbeans project and then refresh (build) it.
Here's what worked for me:
> git clone https://github.com/path/project
Then in NetBeans: File > New Project > choose a project type "...with Existing Sources" > "Next" select "Source Folder" (the folder you cloned into) and press "Finish"
Unfortunately, it seems that your project must already correspond to a project type that NetBeans already supports (eg. Java Application, HTML5/JS Application, etc). If it doesn't you probably won't get this to work.
