When collaborating with others on a Git repository, merge conflicts can occur when Git is unable to automatically merge two or more conflicting branches or commits.

These conflicts arise when different changes are made to the same lines of code or when files are modified in conflicting ways.

This is what a merge conflict error on Git typically looks like:

Resolving merge conflicts is a crucial skill for maintaining a clean and functional codebase.

In this article, we will explore the best solutions ranked from the most effective to the least, enabling you to successfully resolve merge conflicts in your Git repository.

Manual Conflict Resolution

One of the most effective ways to resolve merge conflicts is through manual conflict resolution.

This approach allows you to carefully review the conflicting files, identify the conflicting sections marked by Git, and manually modify the code to create a resolved version.

Example:

$ git status

Identify the files with merge conflicts listed in the output of git status.

$ git diff <file-path>

Inspect the conflict markers in the specified <file-path>.

These markers highlight the conflicting sections that need to be resolved.

Manually edit the file to resolve the conflicts, removing the conflict markers and retaining the desired changes.

$ git add <file-path>

After resolving the conflicts, stage the modified file using git add.

Git Merge Tool

Git provides a built-in merge tool that can assist in resolving conflicts.

The merge tool presents a visual interface that simplifies the process of resolving conflicts by highlighting the conflicting sections and providing tools for merging changes.

Example:

$ git mergetool

Running this command launches the configured merge tool (such as vimdiff, kdiff3, or meld) to help resolve conflicts.

The merge tool displays the conflicting sections side by side, allowing you to choose and merge the desired changes interactively.

Git Abort Merge

In some cases, it may be necessary to abort the ongoing merge process to resolve conflicts.

This option discards the changes from the conflicting branch and restores the repository to its pre-merge state.

Example:

$ git merge --abort

Executing this command cancels the merge in progress, discards all the changes from the conflicting branch, and restores the repository to the state before the merge started.

Git Stash

If you have uncommitted changes that interfere with the merge process, you can temporarily save them using git stash before resolving the conflicts.

After resolving the conflicts, you can apply the stashed changes back to your working directory.

Example:

$ git stash

This command saves your uncommitted changes.

$ git stash apply

After resolving the conflicts, apply the stashed changes using git stash apply.

$ git mergetool --tool=vimdiff

This command specifically launches the merge tool using vimdiff as the tool. Vimdiff provides a side-by-side comparison of conflicting sections, making it easier to edit and merge changes.

3. Resolving Conflicts Using kdiff3:

$ git mergetool --tool=kdiff3

Executing this command launches the merge tool using kdiff3 as the tool. Kdiff3 offers a graphical interface that presents a clear visual representation of the conflicts, allowing you to merge changes efficiently.

4. Resolving Conflicts Using meld:

$ git mergetool --tool=meld

This command launches the merge tool using meld as the tool.

Meld provides a user-friendly interface with side-by-side comparisons and visual highlighting of conflicts, simplifying the resolution process.

When you run the git mergetool command with the desired tool option, the merge tool interface will open, displaying the conflicting sections and providing options to choose and merge the desired changes.

Use the tool’s instructions to navigate, select changes, and save the resolved file.

Remember to configure your preferred merge tool in your Git settings by using the git config command. For example:

$ git config --global merge.tool vimdiff

This sets vimdiff as the default merge tool.

Using the built-in merge tool offers a convenient way to visually resolve merge conflicts and streamline the conflict resolution process in Git.

How to resolve merge conflicts in git without commit?

When resolving merge conflicts in Git, it’s possible to complete the resolution process without immediately committing the changes.

Here are a few examples of how to resolve merge conflicts in Git without committing:

1. Manual Conflict Resolution:

$ git status

Identify the files with merge conflicts listed in the output of git status.

Open the conflicting file(s) in a text editor and manually resolve the conflicts by editing the conflicting sections.

$ git add <file-path>

After resolving the conflicts, stage the modified file(s) using git add.

Repeat the above steps for each conflicting file.

2. Using Git’s In-Built Merge Tool:

$ git mergetool

Launch the configured merge tool, which provides a visual interface for resolving conflicts.

Manually resolve the conflicts using the merge tool’s features and save the changes.

3. Using Git Stash:

$ git stash

If you have uncommitted changes that interfere with the merge process, use git stash to temporarily save them.

Resolve the merge conflicts by manually editing the conflicting files or using a merge tool.

$ git stash apply

Apply the stashed changes back to your working directory.

4. Using Git Checkout:

$ git checkout --ours <file-path>

Choose “our” version of the conflicting file during conflict resolution. This discards the changes from the other branch and keeps your version.

$ git checkout --theirs <file-path>

Choose “their” version of the conflicting file.

This discards your changes and keeps the other branch’s version.

Manually resolve conflicts in each file using the above commands. By utilizing these methods, you can resolve merge conflicts in Git without immediately committing the changes.

Remember that once conflicts are resolved, it’s essential to review and test the changes before committing them to ensure a clean and functional codebase.

How to ignore merge conflicts in git?

In Git, it’s not possible to directly ignore merge conflicts, as they require manual resolution to ensure code integrity. However, you can configure Git to automatically use a specific strategy for resolving conflicts during merges. Here are some examples:

1. Using “ours” or “theirs” Strategy:

$ git merge --strategy-option=ours <branch-name>

This command merges <branch-name> into the current branch, resolving conflicts by favoring “ours” (the current branch’s version) for all conflicting files.

$ git merge --strategy-option=theirs <branch-name>

This command merges <branch-name> into the current branch, resolving conflicts by favoring “theirs” (the other branch’s version) for all conflicting files.

2. Using Recursive Strategy with “ours” or “theirs”:

$ git merge -s recursive -Xours <branch-name>

This command merges <branch-name> into the current branch using the recursive strategy, resolving conflicts by favoring “ours” (the current branch’s version) for all conflicting files.

$ git merge -s recursive -Xtheirs <branch-name>

This command merges <branch-name> into the current branch using the recursive strategy, resolving conflicts by favoring “theirs” (the other branch’s version) for all conflicting files.

Please note that while these strategies can automatically resolve conflicts by favoring one side, it is crucial to use them judiciously. Blindly ignoring merge conflicts can lead to loss of important changes or introduce inconsistencies in your codebase.

It’s generally recommended to manually review and resolve conflicts by carefully examining the conflicting files, understanding the changes made in each branch, and creating a well-informed resolution that retains the desired modifications.

Remember, resolving conflicts ensures code correctness and collaboration among team members, resulting in a more stable and reliable codebase.

What causes merge conflict in git?

Merge conflicts in Git occur when Git is unable to automatically merge changes from different branches or commits due to conflicting modifications made to the same lines of code or files. Several situations can lead to merge conflicts. Here are some examples:

1. Conflicting Line Modifications:
   When two branches modify the same line(s) of code, Git is unable to determine which change should take precedence, resulting in a merge conflict. For instance:

Branch A:
   int count = 10;

Branch B:
   int count = 20;

2. File Level Conflicts:
   Conflicts can arise when two branches modify the same file but in conflicting ways. For instance, if Branch A renames a file, and Branch B makes changes to the file’s content, a conflict will occur during merging.
3. Conflicting File Deletions and Renames:
   If one branch deletes a file while another branch modifies or renames the same file, Git encounters a conflict when merging the changes.
4. Divergent Commit Histories:
   Merge conflicts can occur when two branches have diverged, meaning they have made different and conflicting changes to the same set of files.
5. Incorrect Automatic Merging:
   In some cases, Git may attempt an automatic merge, but the result does not meet the expected outcome due to conflicting changes. This can happen when Git cannot identify the appropriate changes to merge automatically.

It’s important to note that conflicts are an inherent part of collaborative development, particularly when multiple developers are working on the same codebase. Understanding the causes of merge conflicts helps in proactive conflict resolution and maintaining a clean and consistent codebase.
