What to do if the version control system reports a merge conflict?

A merge conflict in version control systems occurs when two developers have made changes to the same lines of the same file. The system cannot automatically decide which version is correct and requires human intervention.

First, open the file where the conflict occurred using your development environment. Modern editors highlight problematic areas with special markers, separating your branch's changes from the merging branch's changes.

Carefully study both code versions and decide which changes need to be kept and which ones removed. You can choose your version, your colleague's version, or combine them manually into a single working block.

After making edits, remove the conflict markers from the file so that the code becomes syntactically correct. Save the file and add it to the version control system index.

Complete the merge operation using a special process continuation command. It is recommended to run the project build and tests to ensure code functionality after the conflict is resolved.
