Missing Files Warning On XCode Build

Hi, I am getting some weird warnings when generating my Xcode project from the projucer; there are a bunch that read as follows:

file:///Users/myUserName/myProject/JuceLibraryCode/juce_audio_basics.cpp: warning: Missing file: /Users/myUserName/myProject/JuceLibraryCode/juce_audio_basics.cpp is missing from working copy

There are a lot of these ( > 40) for different JUCE library files, but this does not prevent the project from building and running. Any idea what might be causing this?

I think this is a git issue that xcode is warning about.
