人生不如意之事十之八九,合并分支往往也不是一帆风顺的。
准备新的feature1分支,继续我们的新分支开发:
$ git checkout -b feature1Switched to a new branch 'feature1' 修改readme.txt最后一行,改为:
Creating a new branch is quick AND simple. 在feature1分支上提交:
$ git add readme.txt
$ git commit -m "AND simple"[feature1 75a857c] AND simple 1 file changed, 1 insertion(+), 1 deletion(-)
切换到master分支:
$ git checkout master
Switched to branch 'master'
Your branch is ahead of 'origin/master' by 1 commit.
Git还会自动提示我们当前master分支比远程的master分支要超前1个提交。
在master分支上把readme.txt文件的最后一行改为:
Creating a new branch is quick & simple. 提交:
$ git add readme.txt
$ git commit -m "& simple"[master 400b400] & simple 1 file changed, 1 insertion(+), 1 deletion(-)
现在,master分支和feature1分支各自都分别有新的提交,变成了这样:
这种情况下,Git无法执行“快速合并”,只能试图把各自的修改合并起来,但这种合并就可能会有冲突,我们试试看:
$ git merge feature1Auto-merging readme.txtCONFLICT (content): Merge conflict in readme.txtAutomatic merge failed; fix conflicts and then commit the result. 果然冲突了!Git告诉我们,readme.txt文件存在冲突,必须手动解决冲突后再提交。git status也可以告诉我们冲突的文件:
$ git status# On branch master# Your branch is ahead of 'origin/master' by 2 commits.## Unmerged paths:# (use "git add/rm ..." as appropriate to mark resolution)## both modified: readme.txt#no changes added to commit (use "git add" and/or "git commit -a") 我们可以直接查看readme.txt的内容:
Git is a distributed version control system.
Git is free software distributed under the GPL.
Git has a mutable index called stage.
Git tracks changes of files.> feature1
Git用标记出不同分支的内容,我们修改如下后保存:
Creating a new branch is quick and simple. 再提交:
$ git add readme.txt
$ git commit -m "conflict fixed"[master 59bc1cb] conflict fixed
现在,master分支和feature1分支变成了下图所示:
