从远端获取最新的代码mirror

git clone --mirror remote/AAA.git

从本地A获取分支

git clone localhost/AAA.git

git check -b master-dev

echo "aaa"> test.txt

/// add commit

git push origin master-dev:master-dev

从本地B获取分支

gitclone localhost/AAA.git

git check master-dev

echo 'bbbb">text.txt

//add commit

git push origin master-dev

///

然后A + B就可以分布式开发了。
