Nar-maven-plugin and native-library-loader don't load native lib

I am testing with nar-maven-plugin, then in next project I need JNI :( I selected it0003 example from git repo. Without loader on native library, manual library placement and setting library path starts. Then I will use loader based on native library. For this I added dependency and assembly-plugin for one JAR file. My current pom is:

Then I put the resulting JAR and NAR in the same directory and started with:

    rd4@PC222-VirtualBox ~/Schreibtisch/nartest $ java -Djava.library.path=/home/rd4/Schreibtisch/nartest/ -jar it0003-jni-1.0-SNAPSHOT-jar-with-dependencies.jar 

      

        
        
        
      

    

Then I get the following error:

java.lang.RuntimeException: Library 'libit0003-jni-1.0-SNAPSHOT.so' not found!
    at it0003.NarSystem.getLibPath(NarSystem.java:141)

Does anyone know what my mistake is?
