It's not quite related to the problem you're having, but our parent pom's have
this in them:
<!-- Reverting back to beta version of the site plugin. v3.0 does
not inherit the properties ('site.deploy.url'
under the 'distributionManagement' section) and results in invalid
href links during the site generation -->
<plugin>
<artifactId>maven-site-plugin</artifactId>
<version>3.0-beta-3</version>
</plugin>
which you may want to file away for future reference…
