Hi Gilles,
I'd like to call a commmand "cmd" as follows:
$ cmd --foo a --foo b --foo c cmdArg1 cmdArg2
There can be any number of arguments to the option "--foo". When I try,
the parser ("GnuParser") considers the "cmdArg1" and "cmdArg2" arguments as
arguments to the "--foo" option.
This is so even with the "stopAtNonOption" flag set to true.
This is possible by declaring the foo option with exactly one argument.
Here is an example:
Options options = new Options();
options.addOption(OptionBuilder.hasArg().create("foo"));
CommandLine cmd = new GnuParser().parse(options, new String[] {
"--foo", "a", "--foo", "b", "--foo", "c", "cmdArg1", "cmdArg2"});
String[] values = cmd.getOptionValues("foo");
When I try
$ cmd --foo 'a b c' cmdArg1 cmdArg2
I don't get 3 separate option arguments "a", "b", "c", but a single string
"a b c".
By using quotes the value 'a b c' is kept as is, the parser will never
try to split it. If the argument was a path containing a space you
certainly wouldn't want to split the value.
