I strongly believe that the marker logic needs fixing, in particular as LilyPond compilation during build can be disabled.
I think I am correct in assuming that the outdated-Marker is intended to mark a file as needing compiling by LilyPond. So this marker should be removed only if a compile has actually taken place (CompilerJob#run).
Once this error is fixed, the functionality of OutdatedMarkerAdder needs to be checked.
