Robert Scholte commented on MNG-3258:
-------------------------------------
This issue is probably outdated. By now almost every plugin has it's own
help-goal, which is much easier to use compared to the maven-help-plugin.
> the command "mvn -help" should describe the usage of the maven help plugin

> The help system in maven (and any other program as well) is typically what
> you use if you can't remember the syntax for a given command. The syntax for
> the help plugin is, however no simpler than any other command, and I always
> find myself ending up with searching google for info on how to use the help
> system to find out how to use, for instance, the dependency plugin.
> I have suggested a new goal "mvn help:help" in the help plugin to use for
> getting info on how to use the help system. The same info should be printed
> when a user types "mvn -help".
