Piotr Zygielo commented on MPMD-403:
------------------------------------
For completeness - with {{:pmd}} being reporting plugin, and with no goal (that
I could find) to do non-reporting analysis to produce {{pmd.xml}} only, with
reporting context (and checking for {{{}skin{}}}) being prepared early, I'm
able to work around my original problem, by configuring {{doxia}} to use other
than {{html}} format (and not fail for project with not updated
{{{}site.xml{}}}).
