Apache commons CLI - repeated options

I've looked around a bit, and this may be just a case of incorrect terminology but is it possible for Apache commons CLI to handle repeated options? eg:

program --arg value1 --arg value2 ...

I know that you can specify multiple option arguments so it will accept stuff like...

program --arg value1 value2

... but I'd like to handle an arbitrary number of repeated options. Does anyone know if/how this is possible?

I've found this question which is somewhat similar, but it was never answered.

Yes, it is possible:

String[] args = { "-arg", "value1", "-arg", "value2" };
CommandLineParser parser = new DefaultParser();
Options options = new Options();
options.addOption("arg", true, "Argument");
CommandLine line = parser.parse( options, args );

String values[] = line.getOptionValues("arg");
System.out.println(Arrays.asList(values));

Result:

[value1, value2]
