The error “You need to resolve your current index first” occurs in Git and indicates that there is a merge conflict, and you will not be able to checkout to another branch until the conflict is resolved. This error message also indicates that a merge failed or that there are file conflicts.
What are these files, merges, and conflicts all about? If you are new to Git, you will be unfamiliar with these terms. Git is a version control system that allows multiple people to work on files at the same time and push their local copy of the code to the cloud.
If you change some downloaded (or previously pushed) code and push it again to the cloud, the changes in the cloud will be overwritten by your local copy.
Git has a branch concept. There is a master branch and several other branches branch out from it. This error occurs most frequently when switching from one branch to another (via checkout) and there are conflicts in the current branch’s files. You will be unable to switch branches unless they are resolved.
What Causes This Error?
As previously stated, the causes of this error are quite limited. You will encounter this error because:
- A merge failed, and you must resolve the merge conflict before proceeding with other tasks.
- There are conflicts in the files at your current (or targeted) branch, and as a result, you will be unable to check out or push code.
Before proceeding with the solution, ensure that you have proper version control and that other team members are not changing the code until you have resolved the conflict.
How To Fix This Error?
1. Fixing Merge Conflict
If Git does not automatically resolve your merge, it leaves the index and working tree in a special state that provides you with all the information you need to resolve the merge. Conflicting files will be highlighted in the index, and you will continue to receive this error message until you resolve the issue and update the index.
- Solve all of the problems. Check the files that have conflicts, as they will be marked by the index, and make the necessary changes.
- After resolving any existing conflicts, add the file and then commit.
- After you’ve resolved the conflict, check out your existing branch to see if the problem has been resolved.
2. Reverting Merge
There are numerous instances where you merge branches and make a mistake. The project is now a shambles as a result of all the conflicts and confusion, and your team members are blaming you for it. In this case, you must undo the previous commit (the merge commit).
This will completely undo the merge and restore the project to its original state before any merges were performed. If you’ve messed things up beyond repair, this can be a lifesaver.
- To undo the merge, enter the following:
$ git reset -–merge
- The command above will reset the index and update the files in the working tree that differ between the ‘commit’ and the ‘head.’ It will, however, keep any files that differ between the index and the working tree.
- You can also use the following command to revert the HEAD:
$ git revert HEAD
- If you want to revert a specific merge commit, you can use the same revert command but with additional parameters. The merge commit’s SHA1 hash will be used.
- The -m followed by the 1 indicates that we want to keep the merge’s parent side (the branch we are merging into).
- As a result of this revert, Git will generate a new commit that undoes the changes made during the merge.
$ git revert -m 1 dd8d6f587fa24327d5f5afd6fa8c3e604189c8d4>
