In Commons RNG, running
  $ mvn clean site site:stage
will generate the Clirr report(s).  See e.g. in
   target/staging/commons-rng-simple/clirr-report.html

[Building with Java 8 here.]

We can support both setups in the parent POM using profiles based on file 
existence e.g. if the profile in the parent is activated by the existence of 
"profile/clirr" every component can activate this profile on its own just by 
creating such a dummy file. This does even work for multi-project setups, 
because you can trigger the profile even in submodules only.

Strange, doesn't seem to work for me. Anyway, I've now switched to use
jacoco and got japicmp to work (will start a new thread for potential
changes to the parent pom).

Thanks
