Well, we have to either override the site plugin version, or downgrade
maven-project-info-reports-plugin to a version that works with the old
site plugin.

Thanks, that explains where the 2.0-beta-7 version for
maven-site-plugin comes from.

I don't think that is viable in the long term.

Another approach (which would allow more uptodate plugins to be used)
would be to use the versions on the page:

http://maven.apache.org/plugins/index.html

We ought to be able to assume that those versions work together.
