Yes, we depend on the project  (but through pom.xml, I guess I can pick 
this up somehow). And I guessed that I could fix this by checking names 
of the projects we depend on. But would this fix be absolutely correct 
or only will fix this particular situation? What if the jar will be 
located somewhere else (for example in source folder of the project we 
depend on)?

This is a default Dali validation which we easily could override.

Only the jar references validation.
