Thinking about it, the patch could be much simpler. Actually all you need is the list of URLs. They are hardcoded but those jar files and your build directory probably will never change again. It looks like netlib-java is unmaintained and changes are unlikely. Please find attached the updated version.
Cheers, Markus
