场景二：从主库发MR到fork库有冲突，怎么解决冲突

问题现象：从主库发MR到fork库有冲突，如何解决

反向合并问题，也就是当主库有更新了，需要将远端主库代码同步到fork的个人仓时，提示有冲突，如何处理？

解决方案：
以上图中的两个仓库为例来解决
主库地址：ssh://git@isource-dg.ztehaha.com:2222/ICP_iSource_OrgTest/DG_0227.git
fork库地址：ssh://git@isource-dg.ztehaha.com:2222/fdd12345/DG_0227.git
分支：均为master
1）clone fork库到本地，并checkout到指定分支
git clone fork库及对应的分支到本地,如fork地址为：ssh://git@isource-dg.huawei.com:2222/fdd12345/DG_0227.git，分支为:master
下载完成后可以使用git remote -v和git branch -a查看仓库地址和分支名是否正确
如果本地已经下载了fork库代码，忽略此步骤

fdd12345@szxy7fdd12345 MINGW64 /d/iSource/TestCode/147/0411
$ git clone ssh://git@isource-dg.huawei.com:2222/fdd12345/DG_0227.git -b master

$ git branch -a
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master

2)同步主库代码，会提示“Conflict”,就表示冲突了。

fdd12345@szxy7fdd12345 MINGW64 /d/iSource/TestCode/147/0411/DG_0227 (master)
$ git pull ssh://git@isource-dg.huawei.com:2222/ICP_iSource_OrgTest/DG_0227.git  master
connected to center DG
remote: 对象计数中: 6, 完成.
remote: 压缩对象中: 100% (4/4), 完成.
remote: Total 6 (delta 2), reused 6 (delta 2)

Auto-merging Platform/GUI_AW_CHN.xml
CONFLICT (content): Merge conflict in Platform/GUI_AW_CHN.xml
Automatic merge failed; fix conflicts and then commit the result.

3)解决冲突
本地fork仓库目录任意空白处右键—>TortoiseGit—>Resolve，弹出框中会显示冲突的文件，开发此时可以选择要解决冲突的文件右键。

说明：
Edit conflicts:编辑冲突文件，适用于远端和本地文件冲突时进行手工合并的场景，编辑后Save并点击Mark as resolved按钮
Resolve conflict using 'theirs':用远端主库上的文件覆盖本地文件，即以远端库上的文件为准
Resolve conflict using 'mine'：用本地文件覆盖远端主库上的文件，即以本地的文件为准

4）解决冲突后再commit并push

fdd12345@szxy7fdd12345 MINGW64 /d/iSource/TestCode/147/0411/DG_0227 (master|MERGING)
$ git add .
git co
fdd12345@szxy7fdd12345 MINGW64 /d/iSource/TestCode/147/0411/DG_0227 (master|MERGING)
$ git commit -a   （弹出框中按:wq即可保存并退出）

这时候主库的代码就全部同步到本地fork的个人库了。
