Description

On Usage Scenarios page http://jakarta.apache.org/commons/cli/usage.html, in the "Java property option" section of "Ant example", after the creation of the property Option, ie :

Option property = OptionBuilder.withArgName( "property=value" )
.hasArg()
.withValueSeparator()
.withDescription( "use value for given property" )
.create( "D" );

One should add :

property.setArgs(Option.UNLIMITED_VALUES);

for the example to work properly.

In the "Querying the commandline" section, the code line :
this.buildfile = line.getValue( "buildfile" );

should be :
this.buildfile = line.getOptionValue( "buildfile" );

Also some parsing code could be given about the special property option, for instance :

Properties props = new Properties();

if( line.hasOption( "D" ) ) {

String[] args = line.getOptionValues( "D" );

for (int i = 0; i < args.length; i += 2)

{ String propertyName = args[i]; String propertyValue = null; if (i + 1 < args.length) propertyValue = args[i + 1]; props.put(propertyName, propertyValue); }

}
