Hello.
I have wrote a simple JOGL application.

public class Main implements GLEventListener {
    private GLU glu;
    private GLUT glut;
    private GL2 gl;
    public static void main(String[] args) {

        GLProfile glProfile = GLProfile.getDefault();
        GLCapabilities capabilities = new GLCapabilities(glProfile);
        GLWindow window = GLWindow.create(capabilities);

        window.setTitle("JOGL test");
        window.setSize(1024, 720);
        window.setVisible(true);

        window.addWindowListener(new WindowAdapter() {
            @Override
            public void windowDestroyed(WindowEvent e) {
                System.exit(0);
            }
        });

        window.addGLEventListener(new Main());
        FPSAnimator fpsAnimator = new FPSAnimator(window, 60);
        fpsAnimator.start();
    }

    @Override
    public void init(GLAutoDrawable drawable) {
        glu= GLU.createGLU(drawable.getGL().getGL2());
        glut=new GLUT();
        gl=drawable.getGL().getGL2();
    }

    @Override
    public void dispose(GLAutoDrawable drawable) {

    }

    @Override
    public void display(GLAutoDrawable drawable) {
        gl.glClear(GL2.GL_COLOR_BUFFER_BIT);
        gl.glClearColor(0f, 0f, 0f, 0);
        gl.glMatrixMode(GL2.GL_MODELVIEW);
        gl.glLoadIdentity();
        glu.gluLookAt(5, 5, 5, 0, 0, 0, 0, 1, 0);

        gl.glColor3f(0.6f,0.6f,0.6f);
        glut.glutSolidCube(1);
    }

    @Override
    public void reshape(GLAutoDrawable drawable, int x, int y, int width, int height) {
        gl.glViewport(0,0,1024,720);
        gl.glMatrixMode(gl.GL_PROJECTION);
        gl.glLoadIdentity();
        glu.gluPerspective(40,(float)1024/720,0.1f,3000);
        gl.glMatrixMode(gl.GL_MODELVIEW);
    }

It's really simple. In IDE (Intellij IDEA) it works fine. But when I have built a JAR file using Maven and tried to run it - i got an exception.

Exception in thread "main" java.lang.UnsatisfiedLinkError: Can't load library: D:\IdeaProjects\jogl-test\target\gluegen-rt.dll

Okay. Actually I thought that Maven will download all needed libraries.
Then i have placed gluegen-rt.dll into a folder with JAR file and tried again to run it, but got another exception.

Exception in thread "main" java.lang.UnsatisfiedLinkError: jogamp.common.os.MachineDataInfoRuntime.getPointerSizeInBytesImpl()I
        at jogamp.common.os.MachineDataInfoRuntime.getPointerSizeInBytesImpl(Native Method)

So is there a problem with libraries?  How to make it run?
I use this dependencies.

<dependency>
            <groupId>org.jogamp.gluegen</groupId>
            <artifactId>gluegen-rt</artifactId>
            <version>2.3.1</version>
        </dependency>

        <dependency>
            <groupId>org.jogamp.jogl</groupId>
            <artifactId>jogl-all</artifactId>
            <version>2.3.1</version>
        </dependency>
