Git: Merge a Commit into a different Branch

问题:

So I have 3 branches;

• develop - my continued development branch
• version_1 - a release branch
• version_2 - a release branch

I had to do a hotfix on version_2 to reship that version, it was a 2 line change in 2 files, very small.

I wanted to apply that fix to version_1 and develop.

So I;

git checkout version_1 git merge <commit checksum> 

I thought a commit only contains the changes, so would only apply those. But the merge conflicts because it tries to update all the changes between the two branches.

Is there a way to merge/move/apply ONLY the changes in a small commit to other branches?

I could just manually re-implement the hotfix on those branches, but this seems a lot of hard work, especially as more hotfixes may need to re applied and rolled out to all other branches.

Cheers, Will 

回答1:

Merging only one or a few commits mean using git cherry-pick

First cancel the merge you just did: see "Undo a Git merge?".
Then:

git checkout version_1 git cherry-pick <commit checksum> 

That can apply to multiple commits or a range of commits: see "How to cherry pick a range of commits and merge into another branch".

回答2:

You need to cherry-pick those commits.

Switch to the branch where you want to add the commits:

git checkout develop 

Then, cherry-pick the commit. First do a git reflog and get the SHA-1 of the commit of the hotfix.

Then, while you are on the branch develop, cherry-pick it

git cherry-pick <commit SHA obtained above> 

Perform similar actions on the other branch version_1.
