git cherry-pick. 如何把已经提交的commit, 从一个分支放到另一个分支
实际问题:
在本地 master 分支上做了一个commit ( 38361a68138140827b31b72f8bbfd88b3705d77a ) , 如何把它放到 本地 old_cc 分支上?
办法之一: 使用 cherry-pick. 根据git 文档:
Apply the changes introduced by some existing commits
就是对已经存在的commit 进行apply (可以理解为再次提交)
简单用法:
git cherry-pick <commit id>
例如:
$ git checkout old_cc
$ git cherry-pick 38361a68 # 这个 38361a68 号码,位于:
$ git log
commit 38361a68138140827b31b72f8bbfd88b3705d77a

1. 如果顺利,就会正常提交。结果:
Finished one cherry-pick.
# On branch old_cc
# Your branch is ahead of 'origin/old_cc' by 3 commits.
2. 如果在cherry-pick 的过程中出现了冲突
Automatic cherry-pick failed. After resolving the conflicts,
mark the corrected paths with 'git add <paths>' or 'git rm <paths>'
and commit the result with:
git commit -c 15a2b6c61927e5aed6718de89ad9dafba939a90b
就跟普通的冲突一样,手工解决:
2.1 $ git status # 看哪些文件出现冲突
both modified: app/models/user.rb
2.2 $ vim app/models/user.rb # 手动解决它。
2.3 $ git add app/models/user.rb
2.4 git commit -c <新的commit号码>
