Scenario : You have updated a file that already existed in main branch and want to remove it from the pull request.
Assume you're working on a branch (say featureBranch) off of development (means you created featureBranch from the development branch) , and your pull request includes a file named AccountController.java.
To remove this file from the pull request and revert its changes, simply do :
1. Checkout your branch (featureBranch).
2. Run below command.
git checkout development -- AccountController.java
3. Commit and push into your branch (featureBranch).
