Got NoSuchMethodError exception by executing a jar file with startCanvas

[W-C_Chu]

I embed JMonkey into a JFrame, so I use startCanvas().
It works fine by the “Run Project” of NetBeans, but If I package my project into a jar file and execute it, I got an Exception:

 com.jme3.system.JmeDesktopSystem initialize
Info: Running on jMonkeyEngine 3.2-stable
 * Branch: HEAD
 * Git Hash: 95d33e6
 * Build Date: 2018-01-05
Exception in thread "jME3 Main" java.lang.NoSuchMethodError: com.jme3.system.lwjgl.LwjglAbstractDisplay.loadNatives()V
        at com.jme3.system.lwjgl.LwjglAbstractDisplay.run(LwjglAbstractDisplay.java:209)
        at java.lang.Thread.run(Thread.java:748)

So I change “startCanvas()” to “start()”, it works. But I need to embed my canvas into a JFrame, what should I do?
Here is my code

package ViveReader;

import java.awt.*;
import javax.swing.*;

public class Main extends JFrame {
    public static Main main = null;
    public static JPanel canvasPanel = null;
    public static int canvasSize[] = {1200, 900};

    public static void main(String[] args) {
        main = new Main();
        new Play();
    }

    public Main() {
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        this.getContentPane().setBackground(Color.decode("#f5f5f5"));
        this.setSize(canvasSize[0], canvasSize[1]);
        this.setLocationRelativeTo(null);
        this.getContentPane().setLayout(new BorderLayout());
        this.setVisible(true);
        this.toFront();
        this.setResizable(false);


        canvasPanel = new JPanel();
        canvasPanel.setLayout(new BorderLayout());
        this.add(canvasPanel);
    }
}

and the Play class

package ViveReader;

import com.jme3.app.LostFocusBehavior;
import com.jme3.app.SimpleApplication;
import com.jme3.material.Material;
import com.jme3.math.ColorRGBA;
import com.jme3.scene.Geometry;
import com.jme3.scene.shape.Box;
import com.jme3.system.AppSettings;
import com.jme3.system.JmeCanvasContext;
import java.awt.Canvas;
import java.awt.Dimension;

public class Play extends SimpleApplication {
    public Canvas coreCanvas = null;
    private static AppSettings appSettings = null;

    public Play() {
        super();
        appSettings = new AppSettings(true);
        appSettings.setResolution(Main.canvasSize[0], Main.canvasSize[1]);

        this.setLostFocusBehavior(LostFocusBehavior.Disabled);
        this.setSettings(appSettings);
        this.setShowSettings(false);

        JmeCanvasContext jmeCanvasContext = null;
        this.createCanvas();
        jmeCanvasContext = (JmeCanvasContext) this.getContext();
        jmeCanvasContext.setSystemListener(this);
        Dimension dim = new Dimension(Main.canvasSize[0], Main.canvasSize[1]);
        jmeCanvasContext.getCanvas().setPreferredSize(dim);
        Main.canvasPanel.add(jmeCanvasContext.getCanvas());
        this.startCanvas(true);
        Main.canvasPanel.repaint();
        Main.canvasPanel.revalidate();
    }

    @Override
    public void simpleInitApp() {
        Box b = new Box(1, 1, 1); // create cube shape
        Geometry geom = new Geometry("Box", b);  // create cube geometry from the shape
        Material mat = new Material(assetManager,"Common/MatDefs/Misc/Unshaded.j3md");  // create a simple material
        mat.setColor("Color", ColorRGBA.Blue);   // set color of material to blue
        geom.setMaterial(mat);                   // set the cube's material
        rootNode.attachChild(geom); 
    }

    @Override
    public void simpleUpdate(float tpf) {
    }
}

Thanks
