In the main class add the following element



@Option(name = "-date", required = true, metaVar = "mmddyyyy", usage = "date for which we want this to happen")

private String date = null;



Within the main method add code to parse command line args and populate date 



public static void main(String args[]){

           try {

         parser.parseArgument(args);

         SimpleDateFormat commandLineDateFormat = new SimpleDateFormat("mmddyyyy", Locale.getDefault());

               Date date = commandLineDateFormat.parse(date);



       } catch (Exception ex){

          ex.printStackTrace();

       }

}
