Problem for downloading android source code for vim2

Hi Everyone
did you come across the error when download android source code for vim2.
My terminal always stuck at fetching object, details you can refer to the capture.

do you know how to deal with this case?

I already re-direct the download source from google to Tsinghua mirror.
and I followed the method found in the internet. “git global --config post.Buffer 2000000000”, but it doesn’t works.

Are you in China? Did you try download source code with VPN?

Yes, I am in China. I haven’t try downloading the source code with VPN.

always stuck at 99%. Can you help me, Terry?
