The javah target of the maven-nar-plugin only scans a single
<classDirectory> directory for actual *.class files, reads their
method signatures and only adds the class if there is at least one
"native" method. The <includes> parameter does not help here.

I added a <extraClasses> parameter to it that just adds its values
to the end of the javah call and with that it would work.
My pull requests for the maven-nar-plugin are here:
 * https://github.com/maven-nar/maven-nar-plugin/pull/22
 * https://github.com/maven-nar/maven-nar-plugin/pull/21
