Subject [jira] Commented: (MPLUGIN-40) All plugins should by default have an auto-generated goal 'help'
Date Fri, 01 Feb 2008 10:41:58 GMT


Tobias Roeser commented on MPLUGIN-40:

This is not working with the current maven-plugin-plugin (version 2.3).

I couldn't find the svn repository to this plugin, just the tags svn repo with version 2.3
which is to old.

The error message is:

This should be auto-generated if it doesn't already exist as a goal in the mojo. The autogenerated
help should typically list the goals (and settable properties) of the plugin, and probably
also print out the url to the plugin's website (if available). This will most likely affect
the plugin archetype as well, I guess.
