    Resolution: Won't Fix

requiresReports doesn't do what you need here.

Please try @aggregator on the report that is configured in the root project - this should ensure that it is not run on the subprojects, but that you have access to the list of projects via ${reactorProjects}. For each of the projects, you can get the list of reports (which should have been executed by now), and process them accordingly. I don't know how you intend to process them, so there may be more information required.

> I am writing a plugin that aggregates the reports from other plugins.  It therefore makes sense that the requresReports tag be set to true, as this plugin does require that the other reports have been generated.
> in dicussion on the users@maven list Brett Porter suggested:
> >You need to use the reports, so declare:
> >@parameter expression="${reports}"
> >That will trigger it. But are you sure you relly need access to the reports? That's generally only for the site plugin.
> but that's a parameter setting, and does not seem to be bound to the mojo wide requiresReports tag.

> It's quite possible I have failed to properly understand the usage of the requiresReports tag.
