using JNI Maven module

[Adraas]

I create multimodule project by means Maven. One of the modules contains native code and marked as NAR by means nar-maven-plugin. Other module downloads previously mentioned JNI module. Question: how to add JNI dependency to an other module?
I tried to add <type>nar</type> duaring adding JNI dependency, but then the source code of the desired module was not available to me, although the assembly was, on the contrary, successful.
