When multiple contributors edit the same code segments in a Git repoistory, a merge conflict occurs. Resolving these conflicts is essential for maintaining code integrity in collaborative Java development.
Procedure for Conflict Resolution
The sequence for addressing a merge conflict involves synchronizing local and remote repositories, merging changes, and manually reconciling discrepancies.
| Step | Action |
|---|---|
| 1 | Update Local Repository |
| 2 | Switch to Target Branch |
| 3 | Fetch Latest Remote Changes |
| 4 | Merge Remote into Local |
| 5 | Manually Resolve File Conflicts |
| 6 | Commit the Resolution |
| 7 | Push Changes to Remote |
Detailed Steps
1. Update Local Repository
Pull the latest commits from the remote branch to insure your local history is current.
git pull origin main_branch
2. Switch to Target Branch
Navigate to the branch where the conflict needs resolution.
git checkout feature_branch
3. Fetch Latest Remote Changes
Retrieve the most recent state of the remote branch without merging it.
git fetch origin feature_branch
4. Merge Remote into Local
Integrate the fetched remote changes into your current working branch.
git merge origin/feature_branch
If conflicts exist, Git will pause the merge and mark the problematic files.
5. Resolve File Conflicts
Open files marked with conflict markers (<<<<<<<, =======, >>>>>>>). Edit these sections to produce the correct final version, removing the markers.
6. Commit the Resolution
Stage the resolved files and create a commit documenting the conflict resolution.
git add .
git commit -m "Merge branch 'feature_branch'; resolve conflicts in UserService.java"
7. Push Changes to Remote
Upload the resolved merge commit to the shared repository.
git push origin feature_branch
