Review Comment:
I'm surprised you have to write this logic. Shouldn't sbt already have this
kind of logic built in somewhere?
I mean if you overwrite a file with the exact same contents, sbt doesn't
rebuild based on that normally does it? It's not purely date-based reasoning. I
thought it created a hash value and only rebuilds if both the date and hash
value changed.
