Emmanuel Bourg resolved CLI-93.
-------------------------------
Resolution: Duplicate
This issue has been addressed in CLI-149, the exception message displays the
missing options.
> Better exception messages when validating required fields
> ---------------------------------------------------------
>
> Key: CLI-93
> URL: https://issues.apache.org/jira/browse/CLI-93
> Project: Commons CLI
> Issue Type: Improvement
> Affects Versions: 1.0
> Reporter: Daniel Spangler
> Priority: Minor
> Fix For: 1.2
>
>
> If the exception messages when required fields aren't found were worded a bit
> better, it would prevent users of this API from having to regenerate messages
> to their users on what went wrong. As it is now, the exception message just
> states the names of the options that were not found. If this message
> contained
> some phrase stating something like: "The following required fields were not
> found: -r, -g.", then we could just pass the exception message on to the
> user.
> A better way to approach the problem might be some sort of way to customize
> common error messages as long as it was done in a way that would reduce the
> amount of coding needed by the user of the API.
