Tycho cannot build client Product, problem with custom defined feature - eclipse

Question

I use Maven/Tycho for building Eclipse RCP project and p2-maven-plugin for building the p2-site located on localhost. Calling mvn clean install on parent pom should build all modules and create client product zip, but some errors appear while building the product.

Yes, I see the problem too - Product cannot see custom (in my project defined) feature called cz.tigra.spl:cz.tigra.spl.client.feature. My question is how to tell the Product where is my feature located/or where is path to its feature.xml (am I right?).

So I guess it isn't enought to have cz.tigra.spl.client.feature located on p2 site, because Product cannot see it - where it should be? Or what is need to be changed in project setup?
Thanks!
