CLI: ParseException:Unrecognized option: -p

[Jürgen Weber <we...@hotmail.com>]

Hello,

if I try the test below there is a ParseException I cannot explain. Is my 
code wrong or is there a bug in CLI (1.0) ?

Thanks,
Juergen

java version "1.4.1_01"


C:\lib>java -classpath  .;commons-cli-1.0.jar  CliTest
Commandline ParseException:Unrecognized option: -p

------------------------- CliTest.java ------------
import org.apache.commons.cli.*;

public class CliTest
{

	public static void main(String[] args)
	{
		String[] argus={

		"-pkg","package","-td","../gen","Method.dtd"

		};

		parseCommandline(argus);
	}


	private static void parseCommandline(String[] args)
	{
		String s=null;

		Options tOptions = new Options();

		tOptions.addOption("i", true, "input data folder");
		tOptions.addOption("td", true, "output folder");
		tOptions.addOption("pkg", true, "package");

		CommandLineParser parser = new PosixParser();

		try
		{
			CommandLine line = parser.parse(tOptions, args);
		}
		catch (ParseException exp)
		{
			System.out.println("Commandline ParseException:" + exp.getMessage());
		}

	}
}

Hi Jürgen,

The option you create here:
> 		tOptions.addOption("pkg", true, "package");
states that the shortOpt value for this option is 'pkg'.
Any shortOpt that is created with a value whose lenght is
greater than one should be parsed using the GnuParser.

So if you replace:
> 		CommandLineParser parser = new PosixParser();
with:
    CommandLineParser parser = new GnuParser();
then things should behave as you would like.

Cheers,

p.s. small point of note, this is really a commons-user mail,
it just makes it easier for some peoples filters.  The other
thing is that when you send a mail to commons-xxx you should
begin your mail with [sub-project] e.g. [cli], again this
helps peoples filters.
