I am currently using NetBeans with GitHub to save my project. However, I've been having some trouble committing the changes. It keeps producing errors that I have been unable to solve, even after looking them up on the internet. I have attached a video of the errors.

Check first with a git status (in command line) if you see pom.xml as untracked, or locally modified: you might need to add and commit it first, before attempting your pull again.
