I downloaded a github repo, created a project in eclipse, pushed the project contents to a server via a metadata API, did some work etc. Its possible that the metadata API process might have modified my files in some way because now in Sourcetree I'm seeing all of my repo files in the 'Show Modified' filter list. When I click on any of them that I didn't manually change the diff window says 'unmodified file'. Any idea what would cause this or how to filter these out?
