# 给 fork 添加源库的clone地址
$ git remote add upstream 源库的clone地址

$ git remote -v
origin  https://outh2:ghp_kY@github.com/quantum6/jdk (fetch)
origin  https://outh2:ghp_kY@github.com/quantum6/jdk (push)
upstream        https://github.com/openjdk/jdk (fetch)
upstream        https://github.com/openjdk/jdk (push)

# 更新与合并
$ git pull https://github.com/quantum6/jdk quantum6
