The PluginDescriptor for the plugin Plugin [...] was not found

Hi,

I hope this is the right place to post this. I have been trying to configure
a code-coverage plugin for my Maven project but keep getting the same error
(I have tried using both Emma and Cobertura):

[ERROR] FATAL ERROR

No doubt this is a basic error on my part. If somebody could help me I would
be very grateful.
