You are working in a team with multiple developers using Git. One of your colleagues has created a feature branch from main, but over time, the main branch has received several commits. Your colleague is now attempting to merge the feature branch into main, but a conflict arises in a file that was modified both in the main branch and in the feature branch. How would you resolve the conflict, ensuring that the feature branch is up-to-date with the latest changes from main and that no work is lost? Additionally, how would you ensure that this situation is prevented in the future?
1. Aa. Merge the feature branch into main without updating main. Resolve conflicts directly in the merge commit. b. Regularly merge main into the feature branch to avoid future conflicts.
2. Ba. Switch to the feature branch and run git pull origin feature-branch. b. Resolve the conflict directly in main, then push the changes.
3. Ca. Ensure main is up-to-date by pulling the latest changes. b. Switch to the feature branch and merge main into it. c. Resolve the conflicts, commit the changes, and push the feature branch. d. Merge the feature branch into main via a pull request. e. Prevent future conflicts by encouraging regular updates between branches.
