ProGuard fails while generating site.

[jinahya]

I configured ProGuard and it works when packaging..

$ mvn clean package

When I tries to generate site, I got,

can't find referenced class net.sourceforge.cobertura.coveragedata.LightClassmapListener

It seems that cobertural changes classes while instrumenting. I'm not sure this problem is related to https://github.com/cobertura/cobertura.
