I'm fairly new to Eclipse and I'm using Kepler with EGit right now but I ran into a problem every time I compile my Java application. I've searched this forum to find a solution for my problem but I am still very confused as to what I can do to fix it. The application worked flawlessly yesterday morning and it works fine on my project partner's laptop but after syncing the project with 4 new commits from my project partner today, I keep getting a Source not found error every time I try to run the application. I get a button saying Edit Source Lookup Path and when I click on it and expand the folders, I get something that looks like this:

There are a bunch of .jar files above what you see and maTKProject is the name of my project.
If anyone could give some insight on how to fix this problem, I would greatly appreciate it!
