Hc2vpp curently uses site plugin to build documentation.
Site configuration is partially inherited form honeycomb parent pom.
To generate links correctly, site pluigin needs single parent,
which requres to duplicate plugin configuration (especially for minimal distribution parent).

Possible woekaround would be to use maven tiles to import plugin configuration,
but maven tiles plugin works by creating artificiall parent projects, which does not work wirth site plugin.
So perhaps separate project that copies contents of asciidoc folders might be solution.
One needs to check if javadocs geneartion still works in such setting.
