Description

MissingArgumentException: no argument for <option> is thrown when the option's
parameter equals to an existing option. Example:
-l option1
-m option2

//this will throw exception
$app -l m

Test case follows:
import junit.framework.*;
import org.apache.log4j.*;
import org.apache.commons.cli.*;

public class CliTest extends TestCase {
CommandLineParser parser;

public CliTest(String name)

{ super(name); }

protected void setUp() throws Exception

{ parser = new PosixParser(); }

public void testParamNamedAsOption() throws Exception {
final String[] CLI_ARGS = new String[]

{"-z", "c"}

;
Option option = new Option("z", "timezone", true,
"affected option");
Options cliOptions = new Options();
cliOptions.addOption(option);
parser.parse(cliOptions, CLI_ARGS);

//now add conflicting option
cliOptions.addOption("c", "conflict", true, "conflict option");
parser.parse(cliOptions, CLI_ARGS);
}
}
