Major Description
The following doesn't work (org.apache.commons.cli.HelpFormatter
)correctly and doesn't print out the help menu of options
that only specify LongOpt.
The output is:
[java] usage: -a | -d | --shutdown | -s | -h [-r <email>] [-f <flight>] [-t]
[java] VendMore - Email Management System
[java] t,-test test mode - makes no permanent changes.
[java] --shutdown shutdown rpc server.
[java] a,-add add user to email queue.
[java] d,-delete delete user from email queue.
[java] f,-flight flight which is the index into the email being sent
[java] h,-help Print this usage information.
[java] -r recipient's email
[java] s,-send send email command
[java] For more information, see Steve Morin
[java] Java Result: 1
it is missing the following options when printing the help display.
options.addOption(OptionBuilder.withDescription("hostname for the XmlRpc
client to connect to.").withLongOpt("hostname").create());
options.addOption(OptionBuilder.withDescription("port for the xmlrpc
client to use.").withLongOpt("port").create());
options.addOption(OptionBuilder.withDescription("additional xmlrpc
connection").withLongOpt("urlpath").create());
options.addOption(OptionBuilder.withDescription("add a parameter
form name=value.").hasArg().withLongOpt("params").create());
