Recently, I fixed several report plugins (changelog, changes etc.) to use Doxia 1.0 and latest maven-reporting-impl.
The main goal was to make reporting plugins available in PDF (see
MPDF-26 and doc )
I notified that running a single report doesn't work but works when coupling with maven-site-plugin 2.0.x.
For instance, run:
In Doxia 1.0, the SiteRenderSink  uses a StringWriter by default to use getBody() in the renderer . So running a single report doesn't write a file with reporting-impl:18.104.22.168
In MPIR 2.1.2, we overrided the mojo.execute() to handle a default renderer  so we are able to run a single report. I propose to move this logic in AbstractMavenReport.
