    Is this the API you were thinking of?
    RequiredParameters required = new RequiredParameters();
    Option input = required.add("input").alt("i").description("Path to input file or directory");
// parameter with long and short variant
    required.add("output"); // parameter only with long variant
    Option parallelism = required.add("parallelism").alt("p").type(Integer.class); // parameter
with type
    Option spOption = required.add("sourceParallelism").alt("sp").defaultValue(12).description("Number
specifying the number of parallel data source instances"); // parameter with default value,
specifying the type.
    ParameterUtil parameter = ParameterUtil.fromArgs(new String[]{"-i", "someinput", "--output",
"someout", "-p", "15"});
    String inputString = input.get();
    int par = parallelism.getInteger();
    String output = parameter.get("output");
    int sourcePar = parameter.getInteger(spOption.getName());
