Merge Conflicts

When merging branches or commits you can get merge conflicts. Git will try to resolve these, but some conflicts need to be resolved manually. Git Extensions will show warnings when there is a merge conflict.


Handle merge conflicts

To solve merge conflicts just click on a warning or open the merge conflict dialog from the menu. A dialog will prompt showing all conflicts. You can solve a conflict by double-click on a filename.


There are three kinds of conflicts:

File deleted and changed Use modified or deleted file?
File deleted and created Use created or deleted file?
File changed both locally and remotely Start merge tool.

If the file is deleted in one commit and changed in another commit, a dialog will ask to keep the modified file or delete the file. When there is a conflicting change the merge tool will be started. You can configure the tool you want to use for merge conflicts. The image below shows Perforce P4Merge a free to use merge tool. Git Extensions is packaged with KDiff3, an open source merge tool.

In the merge tool you will see four versions of the same file:

Base The latest version of the file that exist in both repositories
Local The latest local version of the file
Remote The latest remote version of the file
Merged The result of the merge


When you are in the middle of a merge the file named local represents your file. When you are in the middle of a rebase the file named remote represents your file. This can be confusing, so double check if you are in doubt.
