我正在尝试在 Eclipse 中使用 ASTParser,但遇到 NoClassDefFoundError。我已经遵循了一些指南并导入了相关的 9 个罐子。以下是详细信息:

package test_JDT;

import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;

import org.eclipse.jdt.core.dom.AST;
import org.eclipse.jdt.core.dom.ASTParser;
import org.eclipse.jdt.core.dom.CompilationUnit;
// import org.eclipse.equinox.common.*;

// import org.eclipse.core.jobs;
class tester {

public static void main(String[] args) {
    // TODO Auto-generated method stub
    System.out.println("hello ast parser");
    String javaFilePath = "C:\\Users\\tabzhang\\eclipse-workspace\\test_JDT\\src\\test_JDT/classdemo.java";
    byte[] input = null;
    try {
        BufferedInputStream bufferedInputStream = new BufferedInputStream(new FileInputStream(javaFilePath));
        input = new byte[bufferedInputStream.available()];
        bufferedInputStream.read(input);
        bufferedInputStream.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    String str = new String(input);
    System.out.println(str);
    ASTParser astParser = ASTParser.newParser(AST.JLS3);
    astParser.setSource(new String(input).toCharArray());
    astParser.setKind(ASTParser.K_COMPILATION_UNIT);

    CompilationUnit result = (CompilationUnit) (astParser.createAST(null));
    
    
}

}

包括罐子

命令行

我应该如何让代码运行良好?
