you would add the code from jsmin.rb (that performs god knows what 
purpose) and have that code run against the files...for crawling a 
filesystem you would go about it like this:

#!/usr/bin/ruby

require 'find'

res = []

$stdin.each_line do |file_path|
 res << File.size(file_path.strip) #File.size is only an example..
end                                #I dont know what jsmin.rb contains
                                   #so i cant say what to put there.

#########

usage of this would be as follows

find /etc/ -type f | ./program.rb  # where /etc/ would be the directory 
that the
                                   # java files are in.
