在git合并冲突中，如何保留正在合并的版本？

Question

I have two local git branches on my machine - a branch called "v2" and a branch called "master". I'm merging v2 into master while master is checked out and the head branch.

I'd like to merge the "v2" branch into the "master" branch. When I perform the merge, there are a number of conflicts that I must resolve one by one.

For each conflict, how do I keep the "v2" branch file and not the "master" branch version of the file?

The options presented to me by Git Tower for these types of conflicts are:

• Mark FILENAME as Manually Resolved
• Resolve by Keeping FILENAME
• Resolve by Deleting FILENAME
• Restore Their Version of FILENAME
• Open in External App

From my understanding, the option to "keep" the file meant keeping the "v2" version (the one being merged in) and "deleting" the file meant not adding the "v2" version (but instead keeping the existing "master" version). When I used the delete option, though, it actually deleted the file altogether from the repo.

How do I keep the "v2" branch file and not the "master" branch version of the file for these types of conflicts?

Answer 1

Even though you are using Git Tower, you can drop down to the command line and use

git checkout --theirs file.txt

Here some docs about it:

http://gitready.com/advanced/2009/02/25/keep-either-file-in-merge-conflicts.html

If you want to ONLY use git tower, complete the merge as is, then checkout the other branch's version of that file. Now stage and commit with amend - if possible.

Git has been developed to be a command line tool. With every other tooling that I've ever used, I always had a gap in functionality. I chose to embrace instead of fight the design of Git.

Also, you could hook up something like Beyond Compare and choose "external tool" as is mentioned in your question. There, you will have an option to choose the "theirs" side.

Answer 2

If you're looking to keep v2 hands down (I want master to look exactly like v2), I think the easiest way is to:

• Checkout the branch you want to merge
• Merge master into the branch with the ours strategy
• Checkout master
• Merge the branch

It would look like this:

git checkout v2
git merge -s ours master
git checkout master
git merge v2

If you just want this type of resolution to happen only on conflicts, then you can do:

git checkout master
git merge -s recursive -Xtheirs v2

You can read up on merge strategies in the git documentation here .

UPDATE : unfortunately, I don't think Git Tower exposes a way to do this yet. :-(
