步驟(此處用的是Alibaba/fastjson):

1.將開源專案fork到自己賬號下的倉庫中;

2.將自己倉庫中fork的專案clone到本地;

3.

clone

需要將遠端倉庫clone到本地，此處省略安裝本地github的過程，隨便在哪個目錄(專案存放的目錄)，右鍵開啟一個Git base，執行一下git clone https://github.com/***/***.git

4.上面的命令完成後，當前目錄下會多一個目錄，我clone的是fastjson，所以會多一個fastjson目錄，進到fastjson目錄中，試試跑一下git status試試，會提示現在是master分支。

5.用git remote -v

6.

還需要與上游建立連線，這裡上游指的是一開始fork的那個專案源，以flink為例，執行如下命令：

git remote add upstream https://github.com/apache/flink.git

再用git remote -v可以看到.

此處我自己的倉庫的程式碼是很久以前fork的,所以提交落後原始碼alibaba/master很多;一些步驟使自己倉庫分支與alibaba/master

程式碼保持一致

7.先fetch  : git fetch upstream

8.再rebase :git rebase upstream/master

9.最後再push master

push完後，遠端倉庫便可看到你的branch版本和master分支一致了，否則這個位置會顯示與master相差了多少次commit
