Question

我正在尝试此处找到的 RSyntaxTextArea 示例

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

import org.fife.ui.rtextarea.*;
import org.fife.ui.rsyntaxtextarea.*;

    public class TextEditorDemo extends JFrame {

       private static final long serialVersionUID = 1L;

       public TextEditorDemo() {

          JPanel cp = new JPanel(new BorderLayout());

          RSyntaxTextArea textArea = new RSyntaxTextArea(20, 60);
          textArea.setSyntaxEditingStyle(SyntaxConstants.SYNTAX_STYLE_JAVA);
          textArea.setCodeFoldingEnabled(true);
          textArea.setAntiAliasingEnabled(true);
          RTextScrollPane sp = new RTextScrollPane(textArea);
          sp.setFoldIndicatorEnabled(true);
          cp.add(sp);

          setContentPane(cp);
          setTitle("Text Editor Demo");
          setDefaultCloseOperation(EXIT_ON_CLOSE);
          pack();
          setLocationRelativeTo(null);

       }

       public static void main(String[] args) {
          // Start all Swing applications on the EDT.
          SwingUtilities.invokeLater(new Runnable() {
             public void run() {
                new TextEditorDemo().setVisible(true);
             }
          });
       }
    }

抛出此异常

这里出了什么问题，有什么想法可以解决这个问题吗？

谢谢!

已经找到问题的解决方案

我没有将 RSyntaxTextArea 的源代码复制到我的 Eclipse 项目的 src 文件夹中，而是使用 ANT 构建 rsyntaxtextarea.jar 文件，并将此 jar 文件包含在我的 Eclipse 项目 java 构建路径中。
