我最近在学习叫做PegDown的Java MarkDown库。它似乎在纯粹的MarkDown解析器之上有许多强大的功能。不过，我有以上异常，当我运行下面的代码：当我运行上面的代码简单的Hello world与PegDown？
在该行出现的错误PegDownProcessor pegDown = new PegDownProcessor();
```
import org.pegdown.PegDownProcessor;
public class Proto1 {
private JFrame frame;
private JTextArea markDownRaw = new JTextArea();
PegDownProcessor pegDown = new PegDownProcessor();
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Proto1 window = new Proto1();
window.frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the application.
*/
public Proto1() {
initialize();
}
/**
* Initialize the contents of the frame.
*/
private void initialize() {
frame = new JFrame();
...
JScrollPane scrollPane = new JScrollPane();
frame.getContentPane().add(scrollPane, "flowx,cell 0 0,grow");
markDownRaw.setText("MarkDown here");
markDownRaw.setTabSize(4);
scrollPane.setViewportView(markDownRaw);
JButton btnNewButton = new JButton("Preview");
btnNewButton.addActionListener(new buttonActions());
frame.getContentPane().add(btnNewButton, "cell 0 1,growx,aligny top");
}
/**
* button actions for this class
* @author yuechuan
*
*/
private class buttonActions implements ActionListener {
@Override
public void actionPerformed(ActionEvent e) {
//String markDownRawString = markDownRaw.getText();
//String htmlString = pegDown.markdownToHtml(markDownRawString);
//System.out.println(htmlString);
}
}
}
出现如下异常

任何人都可以给我一个你好世界的例子pegDown？
在此先感谢。
我仍然有同样的问题。依赖项已经添加，如下所示 – cyc115
您正在使用哪种IDE，并且正在从jar文件运行程序？如果您已将程序打包为jar，请在jar文件中检查parboiled-core.jar。 –
