标签：git kaol DESKTOP master 冲突 branch Desktop 分支
在项目开发过程，我们合并分支时经常会碰到冲突的问题，下面通过一个简单的例子演示下冲突是如何产生的以及如何去解决冲突。
1、冲突的产生
1.1、主干分支代码
在主干分支有两个文件
main.cpp
#include <stdio.h>
#include <string.h>
int main()
{
char data[100] = "my branch name is master";
int length = strlen(data);
for(int i = 0; i < length; i++)
{
printf("%c", data[i]);
}
printf("branch master\n");
return 0;
}README.md
this is master branch这个时候tom和jack分别拉取了主干分支的代码，并进行了修改。
1.2、tom修改代码提交合并
tom创建A分支并对文件做了以下修改
main.cpp
#include <stdio.h>
#include <string.h>
int main()
{
char data[100] = "my branch name is A";
int length = strlen(data);
for(int i = 0; i < length; i++)
{
printf("%c", data[i]);
}
printf("branch AAA\n");
return 0;
}README.md
this is AAA branch提交代码并合并到主干

1.3、jack修改代码提交合并
jack对代码做了如下修改
main.cpp
#include <stdio.h>
#include <string.h>
int main()
{
char data[100] = "my branch name is B";
int length = strlen(data);
for(int i = 0; i < length; i++)
{
printf("%c", data[i]);
}
printf("branch BBB\n");
return 0;
}
README.md
this is BBB branch提交代码并合并到主干
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B)
$ git add .
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B)
$ git commit -m "B分支代码提交"

push时产生冲突
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (master)
$ git push origin master
To https://gitee.com/lingpe/kaol.git
! [rejected] master -> master (fetch first)
error: failed to push some refs to 'https://gitee.com/lingpe/kaol.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.

$2、解决冲突
接下来就是如何解决冲突
切换回B分支，然后拉取主干分支代码
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B)
$ git pull origin master
remote: Enumerating objects: 7, done.
remote: Counting objects: 100% (7/7), done.
remote: Compressing objects: 100% (3/3), done.
remote: Total 4 (delta 1), reused 0 (delta 0), pack-reused 0
Unpacking objects: 100% (4/4), 356 bytes | 178.00 KiB/s, done.

Auto-merging main.cpp
CONFLICT (content): Merge conflict in main.cpp
Auto-merging README.md
CONFLICT (content): Merge conflict in README.md
Automatic merge failed; fix conflicts and then commit the result.
拉取失败，可以看到提示信息，告诉我们哪个文件产生了冲突。
直接打开main.cpp文件，可以看到有以下特殊字符，提示我们哪一行代码产生了冲突。
#include <stdio.h>
#include <string.h>
int main()
{
<<<<<<< HEAD
char data[100] = "my branch name is B";
=======
char data[100] = "my branch name is A";
>>>>>>> ccb26269f42245dfcbedfbf2218419c5ab7f2787
int length = strlen(data);
for(int i = 0; i < length; i++)
{
printf("%c", data[i]);
}
<<<<<<< HEAD
printf("branch BBB\n");
=======
printf("branch AAA\n");
>>>>>>> ccb26269f42245dfcbedfbf2218419c5ab7f2787
return 0;
}直接在文件中手动解决冲突。删除文件中的特殊字符，然后根据需求修改代码。
#include <stdio.h>
#include <string.h>
int main()
{
char data[100] = "my branch name is B and A";
int length = strlen(data);
for(int i = 0; i < length; i++)
{
printf("%c", data[i]);
}
printf("branch BBB\n");
printf("branch AAA\n");
return 0;
}
~
同理，对README.md，手动解决冲突。
this is BBB and AAA branch
解决完冲突后提交到B分支
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B|MERGING)
$ git add .
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B|MERGING)
$ git commit -m "解决冲突"
[B f30e1ea] 解决冲突
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B)
$ git push origin B

To https://gitee.com/lingpe/kaol.git
bdcbe03..f30e1ea B -> B
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B)
$
最后将B分支合并到主干，就不会产生冲突了
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B)
$ git checkout master
Switched to branch 'master'
Your branch and 'origin/master' have diverged,
and have 1 and 1 different commits each, respectively.
(use "git pull" to merge the remote branch into yours)
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (master)
$ git merge B
Updating bdcbe03..f30e1ea
Fast-forward
README.md | 2 +-
main.cpp | 4 ++--
2 files changed, 3 insertions(+), 3 deletions(-)
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (master)
$ git push origin master
Total 0 (delta 0), reused 0 (delta 0), pack-reused 0
remote: Powered by GITEE.COM [GNK-6.2]
To https://gitee.com/lingpe/kaol.git
ccb2626..f30e1ea master -> master
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (master)
$
至此，冲突成功解决
可以看下主干分支的代码
main.cpp
#include <stdio.h>
#include <string.h>
int main()
{
char data[100] = "my branch name is B and A";
int length = strlen(data);
for(int i = 0; i < length; i++)
{
printf("%c", data[i]);
}
printf("branch BBB\n");
printf("branch AAA\n");
return 0;
}README.md
this is BBB and AAA branchOK
