GitLab本地、远程更新已经fork的项目

单用IDEA无法做到，必须配合使用Git命令行才能做到，而且是先从原作者项目更新本地库，再从本地库push到自己远程fork项目，非常坑逼。

1.到项目clone的根目录右键Git Bash,先查看远程源，一般只有你自己fork项目的源，没有原作者的，需要添加远程源：

Administrator@admin-PC MINGW64 /e/git_projects/sunfield-microframe-service (master)
$ git remote -v
origin http://172.16.175.36:180/baigang/sunfield-microframe-service.git (fetch)
origin http://172.16.175.36:180/baigang/sunfield-microframe-service.git (push)

Administrator@admin-PC MINGW64 /e/git_projects/sunfield-microframe-service (master)
$ git remote add upstream ssh://git@172.16.175.36:4422/jiaoma/sunfield-microframe-service.git

Administrator@admin-PC MINGW64 /e/git_projects/sunfield-microframe-service (master)
$ git remote -v
origin http://172.16.175.36:180/baigang/sunfield-microframe-service.git (fetch)
origin http://172.16.175.36:180/baigang/sunfield-microframe-service.git (push)
upstream ssh://git@172.16.175.36:4422/jiaoma/sunfield-microframe-service.git (fetch)
upstream ssh://git@172.16.175.36:4422/jiaoma/sunfield-microframe-service.git (push)

Administrator@admin-PC MINGW64 /e/git_projects/sunfield-microframe-service (master)
$ git fetch upstream
The authenticity of host '[172.16.175.36]:4422 ([172.16.175.36]:4422)' can't beestablished.
ECDSA key fingerprint is SHA256:hFUMVxu5yYzhamirMDGSsvo3KbgbsVBQ3ZPTOBUIdqs.
Are you sure you want to continue connecting (yes/no)?
Host key verification failed.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

2.这里添加了原作者ssh协议的源，因为没有本机证书，无法连接成功，所以需要改为添加http协议源，这里本公司GitLab服务器需要带上180端口：

Administrator@admin-PC MINGW64 /e/git_projects/sunfield-microframe-service (master)
$ git remote add upstream http://172.16.175.36:180/jiaoma/sunfield-microframe-service.git
fatal: remote upstream already exists.

Administrator@admin-PC MINGW64 /e/git_projects/sunfield-microframe-service (master)
$ git remote remove upstream

Administrator@admin-PC MINGW64 /e/git_projects/sunfield-microframe-service (master)
$ git remote add upstream http://172.16.175.36:180/jiaoma/sunfield-microframe-service.git

Administrator@admin-PC MINGW64 /e/git_projects/sunfield-microframe-service (master)
$ git remote -v
origin http://172.16.175.36:180/baigang/sunfield-microframe-service.git (fetch)
origin http://172.16.175.36:180/baigang/sunfield-microframe-service.git (push)
upstream http://172.16.175.36:180/jiaoma/sunfield-microframe-service.git(fetch)
upstream http://172.16.175.36:180/jiaoma/sunfield-microframe-service.git(push)

这里需要先使用git remote remove命令移除此前错误添加的同名源（其实起别的名也可以，fetch时从正确名字的源获取即可）

3.从添加的原作者源fetch到本地仓库，合并到本地仓库：

Administrator@admin-PC MINGW64 /e/git_projects/sunfield-microframe-service (master)
$ git fetch upstream
remote: Counting objects: 103, done.
remote: Compressing objects: 100% (65/65), done.

$ git merge upstream/master

4.把更新push到自己远程fork库：

Administrator@admin-PC MINGW64 /e/git_projects/sunfield-microframe-service (master)
$ git push
Enumerating objects: 119, done.
Counting objects: 100% (119/119), done.
Delta compression using up to 8 threads
Compressing objects: 100% (45/45), done.
Writing objects: 100% (103/103), 12.50 KiB | 2.50 MiB/s, done.
Total 103 (delta 24), reused 103 (delta 24)
remote: Resolving deltas: 100% (24/24), completed with 6 local objects.
To http://172.16.175.36:180/baigang/sunfield-microframe-service.git
2970d82..27ca203 master -> master

注意这里应push到自己的远程库，而不是原作者的！

也可使用命令：

git push origin master

这样成功更新了自己本地库、远程fork库，完全不需要IDEA操作了。
