It's impossible to make this work perfectly.
a) Any file can be generated, thus we should
be able to deal with the possibility that
the java source might not exist when we
start the build.
b) In order to resolve dependencies on generated
files correctly, we have to know the locations
of all targets that can be built before we start
to build anything.
