Thomas Neidhart commented on CLI-229:
-------------------------------------
Tested with the latest trunk (1.3-SNAPSHOT), and I receive the following output:
{noformat}
usage: Notice <arg> is missing in seq1 --seq1 <arg> --seq2 <arg>
--seq1 <arg> REQUIRED : the file containing sequence 1
--seq2 <arg> REQUIRED : the file containing sequence 2
{noformat}
> Missing place holder in required argument

> public class CliArgBug {

> // FIXME : bug ? usage prints --seq1 --seq2 <arg> - notice <arg>
> // missing in seq1 - corrected by adding .withArgName("file1")
> OPTIONS.addOption(OptionBuilder
> .withLongOpt("seq1")
> .withDescription(
> "REQUIRED : the file containing
> sequence 1")
> .hasArg().isRequired().create());

> defined - please add this to the javadoc
