無法在獨立Java可執行文件中使用WorldWind

Question

我正嘗試創建一個獨立的Java可執行文件來顯示WorldWind Globe並繼續運行到依賴項問題。下面是我的代碼：

package com.mycompany.testmaven; 

import gov.nasa.worldwind.BasicModel; 
import gov.nasa.worldwind.Configuration; 
import gov.nasa.worldwind.avlist.AVKey; 
import gov.nasa.worldwind.awt.WorldWindowGLCanvas; 
import gov.nasa.worldwind.layers.Layer; 
import gov.nasa.worldwind.render.Offset; 
import gov.nasa.worldwind.util.layertree.LayerTree; 
import javax.swing.JFrame; 
import javax.swing.JPanel; 

public class WorldWindGlobe 
{ 
    public static void main(String[] args) 

    { 
     Layer graticuleLayer = null; 
     WorldWindowGLCanvas worldWindCanvas = new WorldWindowGLCanvas(); 
     worldWindCanvas.setModel(new BasicModel()); 

      // Update layer panel 
     final LayerTree layerTree = new LayerTree(new Offset(20d, 160d, AVKey.PIXELS, AVKey.INSET_PIXELS)); 
     layerTree.getModel().refresh(worldWindCanvas.getModel().getLayers()); 


     //build Java swing interface 
     JPanel panel = new JPanel(); 
       panel.add(worldWindCanvas); 

       JFrame frame = new JFrame(); 
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     frame.add(worldWindCanvas); 
     frame.setSize(800,600); 
     frame.setVisible(true); 
    } 
} 

這是Maven項目我的POM文件：

我能做到這一點的，沒有問題的NetBeans，但第二次我用窗簾插件Maven並在NetBeans之外運行可執行文件我收到以下錯誤：

任何想法爲什麼會發生這種情況？我認爲Shade Plugin將jar包內的依賴包打包，這樣它可以在IDE之外工作？任何幫助將不勝感激。我使用的世界風2.0和Java 8

很多玩弄我可以使用下面的命令來調用獨立的可執行文件後：

java -cp ".;lib/WorldWIndExecutable.jar;lib/*;" com.mycompany.MainClass 

此命令設置類路徑的庫文件夾包含所有必需的World Wind依賴罐。我還需要提取部分WorldWind jar中的dll，以便可以分別調用它們。我希望這能幫助一些有困難的人。
