Hi.
I'm using 1.3.1 for parsing cmdline parameters. I stumbled across an odd things
when working with optional parameters like in the following
example:
public static void main(String[] args) throws ParseException {
Options options = new Options();
options.addOption(
Option.builder("ls").longOpt("logSsl").desc("Activates SSL logging (very
noisy!)").build());
options.addOption(
Option.builder("lr").longOpt("logRequest")
.desc("Activates
request/response logging with a maximum of n bytes per payload (default:
10000)")
.argName("byte-count").optionalArg(true).numberOfArgs(1).build());
CommandLineParser parser = new DefaultParser();
CommandLine line = parser.parse(options, args);
System.out.println(line.getOptionValue("lr"));
}
Executing it with "-lr -ls" returns "-ls". If I invoke it with "-lr 5000 -ls"
it returns 5000.
So it seems, although I marked it as an optional argument, it just takes the
next parameter "-ls"
as an argument for "-lr" - which I wouldn't expect. It could simply identify
whether it is an argument
by simply checking against the list of valid parameters and just return null or
something.
Is this expected behavior? If so, how can I check if an optional argument has
been provided or not?
Thanks.
