Description

I'm not sure if this is fixed in the master branch, but it looks like the HelpFormatter doesn't correctly output a <arg> when the first option has an argument. Sample:

Main.java

    Options options = new Options();
    options.addOption(OptionBuilder.withLongOpt("user").withDescription("Database username").isRequired().hasArg().create("u"));
    options.addOption(OptionBuilder.withLongOpt("pass").withDescription("Database password").isRequired().hasArg().create("p"));

    CommandLineParser parser = new PosixParser();
    CommandLine commandLine;
    try {
      commandLine = parser.parse(options, args);
    } catch (ParseException e) {
      HelpFormatter helpFormatter = new HelpFormatter();
      helpFormatter.printHelp(120, "Usage: Main <options>", e.getMessage(), options, "");
      System.exit(1);
    }

The output is:

usage: Usage: Main <options>
Missing required option: u, p
 -p,--pass <arg>    Database password
 -u,--user          Database username
