Backports has git 2.11.0. Just add the "jessie-backports" suite to your
sources list, e.g.:
   deb http://ftp.<country>.debian.org/debian/ jessie-backports main

And install git from there:
   sudo apt install git/jessie-backports

Apt won't upgrade other packages to backports versions, but any packages
you've manually installed from there will be kept up-to-date.

See https://backports.debian.org/ for more details.
