Jörg Hohwiller commented on MOJO-749:
-------------------------------------
I am sorry, but I can not. The project is an enterprise application for my
customer.
I will try if the problem still occurres when I switch to tree layout. The rest
is pretty convenient but there is also one module that is a webapp with
packaging 'war'.
What I figured out is that somehow maven site:stage is not called on the
modules first but starts on the toplevel project. Maybe when it does
DashBoardUtils.getCoberturaDataFile the coberatura.ser is empty and therefore
the version is null.
