Paul Benedict commented on MNG-4054:
------------------------------------
Brett is right in his analysis. I was partially right. The first character does
trigger the correct mode, but the rest is interpreted as a bogus option. Here's
a bogus option that puts Maven into offline mode when it should just be
rejected outright:

> Key: MNG-4054
> URL: http://jira.codehaus.org/browse/MNG-4054
> Project: Maven 2
> Issue Type: Bug
> Components: Command Line
> Affects Versions: 2.0.10, 2.1.0-M1, 3.0-alpha-1, 3.0-alpha-2
> Reporter: Paul Benedict
> Assignee: John Casey
> Priority: Minor
> Fix For: 2.1.1

>
> The command line interpreter obviously only matches against the starting
> portion of a known option.
> To execute offline, this is acceptable: mvn -outside
> To execute in debug mode, this is acceptable mvn -XOXOXOXOXOX
> You can do this with any option. Get the first couple letters right and
> you'll trigger perhaps an unintended option.
