How can I force IntelliJ to resolve conflicts, which are already committed in a file by another person

Using GIT, I checked out a branch from the remote repository, which another person had worked on. One of the files has conflicts, which are already committed, so the file contains marks like <<<<<<< HEAD etc. Now, is there any way to run IntelliJ conflicts resolving tool, to resolve these conflicts? Or do I need to resolve them by hand?

when conflict happens, you can use the built-in merge tool, do this steps -

• open project where the conflicts need to be resolved.

• checkout the branch with conflicts:

  git checkout your-branch
  

• Open the Version Control Tool in View > Tool Windows > Version Control.

• In the Version Control tool window, go to the Local Changes tab. You will see a list of files with conflicts, marked with a red triangle.

• Initiate the Merge Tool:

  • Right-click on the conflicted file.
  • Select Git > Resolve Conflicts.

• Merge Tool will open a three-way merge tool where you can see:

  • Changes from the current branch on left side.

  • Changes from the branch you are merging on right side.

  • and in center, resulting file where you can choose which changes to keep.

  • Use the buttons above the panes to accept changes from either side or both. You can also manually edit the center pane to resolve the conflict.

• Once you have resolved all conflicts in the file, click Apply to save the merged result and mark the conflict as resolved.

• After resolving all conflicts, commit the changes:

  git add path/to/conflicted-file
  git commit -m "Resolved merge conflicts in path/to/conflicted-file"
  

do this steps , so you dont have to manually edit the conflicted code.

but yes , once the conflict markers are committed, Git no longer considers them as conflicts and now that is part of the file content.

you can still do like this -

• Open the file containing the conflict markers.

• Look for the conflict markers:

  • <<<<<<< HEAD - this is for start of your changes.

  • ======= - this Separates your changes from the incoming changes.

  • >>>>>>> branch-name - shows the end of the incoming changes.

  • now simply Decide which changes you want to keep: the changes between <<<<<<< HEAD and ======= (your changes) or the changes between ======= and >>>>>>> branch-name (the incoming changes).

  • Edit the file to keep the needed changes and remove the conflict markers.

• After resolving the conflicts, Test It.

  • then stage the resolved file:

    git add path/to/file
    

  • Commit the resolved changes:

    git commit -m " resolved conflicts in path/to/file"
