How to resolve merge conflicts?

Rolf Marsh January 4, 2015

I had a branch that I needed to split into two (main branch: 3.2.0, new branch: 3.1.2 which was created by using "checkout".  I made my changes to the new branch and now I want to merge 3.2.0 into 3.1.2.  So I did a merge and now I have 3 files with "conflicts":

So, I look at each file on the right of SourceTree and I see this:

What do I do with this?  What I would like to do is put this file(s) into an editor where I can make the changes.  I don't understand why the other 20 files made it through without any "conflicts" and these three did not... or do I have more of a mess than is showing?

I think your app SourceTree is a god-send... don't know what I would do without it, but I think I really don't understand Git that well to be able to do this on my own.  Thank you for your understanding.

First of all, please do some reading in order to understand what a merge conflict is. Afterwards, you need to do the following:

  1. Install a diff tool that can do 3-way merges, for example KDiff3.
  2. Configure this to be your external diff/merge tool in SourceTree (in Tools/Options/Diff).
  3. In the place where you took the 1st screenshot, right-click on a file, Resolve Conflicts\Launch External Merge Tool
  4. Repeat the previous step for each conflicted file.
  5. Commit (and push) your changes.

Balazs:  boy, that (KDiff3) is one hell of a tool... thank you so much... I appreciate it.

A) I have tried reading the documentation on a merge conflict - it is terrible documentation with lots of explanations but no examples.  Doesn't really work for a visual learner.

B) Step 2 - there is no Tools/Options/Diff.  There is a Preferences option with a Diff tab, but there are no instructions about what to type in the command areas!

C) The "Resolve conflicts" option is not appearing anymore.

This may have been a good answer 4 years ago - it's not really helpful now.
