Understanding the Problem

When working with version control systems like Git, it's common to face challenges when merging branches, especially when there are conflicts involved. In this guide, we'll explore a scenario where two branches—branch1 and branch2—are facing conflicts while trying to merge with the master branch.

Here's a brief overview of the scenario:

The master branch contains an initial commit.

branch1 contains the initial commit plus an additional commit (commit1).

branch2 contains the initial commit plus another additional commit (commit2).

Attempting to merge branch1 into master works fine, but merging branch2 leads to conflicts.

In this post, we will walk through the steps on how to effectively use Git's rebase functionality to resolve these conflicts and successfully merge both branches into master.



Resolving Conflicts with Git Rebase

Step 1: Merge branch1 into master

To start off, we need to first merge branch1 into master. This sets the stage for our subsequent actions.

Open your terminal and execute the following command:

This command will integrate branch1 into master.

After this merge, your Git history will look something like this:

Step 2: Rebase branch2 onto master

Next, you will rebase branch2 on top of master. This is crucial as it will help situate your changes correctly within the context of master.

Run the following command:

During the rebase process, you may encounter some conflicts. Git will let you know as follows:

Step 2.1: Resolve Conflicts

To resolve the conflicts:

Open each conflicted file (in this case, fileXXX) and manually fix the conflicts.

Once you've fixed all issues, add the resolved files:

After marking the conflict as resolved, continue the rebase:

After resolving conflicts and completing the rebase, your Git history will reflect that branch2 has been successfully rebased onto master:

Step 3: Final Merge of branch2 into master

Now that branch2 is rebased and conflict-free, you can merge it back into master.

Switch to the master branch and run the following commands:

After running these commands, master will now include the changes from both branch1 and branch2:

Conclusion

By following the steps outlined above, you can effectively manage and resolve conflicts in Git when merging branches. Utilizing git rebase allows for a cleaner commit history and smoother integration of changes. Remember to always back up your work before rebasing or merging to prevent any unintended data loss.

By understanding how to navigate through merging and rebasing in Git, you can become more efficient in managing your projects and collaborating with others.
