Download the source from git successfully.
I use TortoiseGit UI, select git clone, then input the url.
The url up above the "Pass this URL to ‘git clone‘ to copy the repository locally." on web application console.
Remember: Check the "Load Putty Key", and select the ppk file.
At first I can not download the source code from git because I don‘t know I have to input the Putty Key file.
After commit the code, it will compile automatically, and I get what I want on the page.
Great!
