Graphviz，GEF4並在Java中構建路徑

我編寫了這個java代碼來顯示使用Graphviz和GEF4框架的簡單圖形。什麼是重要的，我也在Eclipse中使用Window Builder。我創建了SWT/JFace Java項目，然後將其轉換爲插件項目。Graphviz，GEF4並在Java中構建路徑

import org.eclipse.swt.widgets.Display; 
import org.eclipse.swt.widgets.Shell; 
import org.eclipse.swt.widgets.Button; 
import org.eclipse.swt.SWT; 
import org.eclipse.gef4.dot.DotImport; 
import org.eclipse.gef4.graph.*; 
import org.eclipse.gef4.zest.fx.*; 
import org.eclipse.gef4.layout.*; 
import org.eclipse.gef4.layout.algorithms.*; 


public class Code1 { 

    public static void main(String[] args) { 
    Display display = Display.getDefault(); 
    Shell shell = new Shell(); 
    shell.setSize(450, 300); 
    shell.setText("SWT Application"); 
    shell.setLayout(null); 


      Graph.Builder graph2 = new Graph.Builder().attr(ZestProperties.GRAPH_LAYOUT, new SpringLayoutAlgorithm()); 
      new DotImport("digraph{1->2}").into(graph2); 
      new DotImport("node[label=zested]; 2->3; 2->4").into(graph2); 
      new DotImport("edge[style=dashed]; 3->5; 4->6").into(graph2); 
      //SpringLayoutAlgorithm SLA= new SpringLayoutAlgorithm(); 
      graph2.build(); 


    shell.open(); 
    shell.layout(); 
    while (!shell.isDisposed()) { 
     if (!display.readAndDispatch()) { 
      display.sleep(); 
     } 
    } 
    } 
}

我有errrors：

我發現我需要在構建路徑添加構建路徑（jar文件所需要的庫）。所以我補充說。我也添加了所有的依賴關係。但它仍然不起作用。你有什麼想法，我可能會錯過什麼？謝謝你的任何想法！

我會很感激任何想法，任何提示！謝謝！ – sourire09

您應該找到org.eclipse.emf.ecore.resource.ResourceSet lib並將文件jar添加到elipse中。
