Right now if you put a file path in extraResources or extraFiles, you get an error "directory does not exist".
It would be nice to be able to put a single file in there. The idea is that you can use this to rename a file while packaging.
For example i have a node_modules which comes with a toto.js and toto.min.js. and it requires the toto.js. In prod i would like to package the min instead, but for it to be required correctly i need to rename the min file.
