[jira] [Created] (CLI-233) HelpFormatter missing for first option

["Brian Pontarelli (JIRA)" <ji...@apache.org>]

Brian Pontarelli created CLI-233:
------------------------------------

             Summary: HelpFormatter missing <arg> for first option
                 Key: CLI-233
                 URL: https://issues.apache.org/jira/browse/CLI-233
             Project: Commons CLI
          Issue Type: Bug
          Components: CLI-1.x
    Affects Versions: 1.2
            Reporter: Brian Pontarelli
            Priority: Minor
             Fix For: 1.3


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:


    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
