git 合并远程分支(带冲突)

应用场景

团队中两人同时fetch了一个分支。 第一个人修改后提交，第二个人提交就失败。失败信息如下:

 error: failed to push some refs to '[email protected]:jacarrichan/jacarrichan.git'
 hint: Updates were rejected because the remote contains work that you do
 hint: not have locally. This is usually caused by another repository pushing
 hint: to the same ref. You may want to first integrate the remote changes
 hint: (e.g., 'git pull ...') before pushing again.
 hint: See the 'Note about fast-forwards' in 'git push --help' for details.

虽然使用“git push -f  ”也可以提交，但是会将remote上第一个人的改动冲掉，太暴力了，不太好。下面说的是手动合并.  

解决办法

1，获取远程分支更新，也就是第一个人提交的：

 git fetch origin

2，尝试由git带来的自动合并：

 git merge origin/master     ##将origin/master合并到当前分支

如果 两个分支的内容有差异 ，否则提示合并失败。

 Auto-merging README.md
 CONFLICT (content): Merge conflict in README.md
 Automatic merge failed; fix conflicts and then commit the result.

看下当前的状态，寻找帮助信息：

 jacarri@JACARRI-PC /F/temp/mvn/jacarrichan (master|MERGING)
 $ git status
 # On branch master
 # You have unmerged paths.
 #   (fix conflicts and run "git commit")
 #
 # Unmerged paths:
 #   (use "git add ..." to mark resolution)
 #
 #       both modified:      README.md
 #
 no changes added to commit (use "git add" and/or "git commit -a")

现在我们再来看一下工作目录里的“README.md”文件的内容：

 jacarri@JACARRI-PC /F/temp/mvn/jacarrichanc (master|MERGING)
 $ cat README.md
 #jacarrichan




 Only for ochina git test.


 <<<<<<< HEAD
 这是第二个人提交的......................
 =======
 这是第一个人提交的
 >>>>>>> origin/master

 )

“<<<<<<< HEAD“下面就是当前版本里的内容；而“=======”之下，“>>>>>>>origin/master”之上则表示测试分支里与之对应的有冲突的容。修复冲突时我们要做的，一般就是把“ <<<<<<< HEAD”，“=======”和“ >>>>>>> test”这些东东先去掉，然后把代码改成我们想要的内容。

需安装配置BeyondCompare，下载地址 

 [diff]
     tool = bc3
 [difftool "bc3"]
     cmd = \"D:/application/BeyondCompare/BCompare.exe\" \"$LOCAL\" \"$REMOTE\"
     trustExitCode = true
 [difftool]
     prompt = false
 [merge]
     tool = bc4
 [mergetool "bc4"]
     cmd = \"D:/application/BeyondCompare/BCompare.exe\" \"$LOCAL\" \"$REMOTE\" \"$BASE\" \"$MERGED\"
     trustExitCode = true

手动合并

 jacarri@JACARRI-PC /F/temp/mvn/jacarrichanc (master|MERGING)
 $ git mergetool  README.md
 Merging:
 README.md

 Normal merge conflict for 'README.md':
   {local}: modified file
   {remote}: modified file
 Hit return to start merge resolution tool (bc4):

备注：图片上方的三个深蓝色圈住的和配置文件中的这个对应“ \"$LOCAL\" \"$REMOTE\" \"$BASE\" \"$MERGED\"”.

 按照上述规则，我选择把双方的内容都添加进来,你采纳第一个或者另外写别的内容都可以。  保存后重新提交就顺利.
