java - 如何解决 java jackcess 依赖错误？

Question

我正在尝试显示来自 MS Access 数据库的数据，我正在使用 Jackcess 库，但我遇到了一个我不知道如何解决的依赖性错误。这是我的代码和错误:

import com.healthmarketscience.jackcess.*;
import java.io.*;
import java.util.*;
import java.sql.*;
import java.nio.*;
import java.lang.*;
import org.apache.commons.*;
import org.apache.commons.lang3.builder.*;
import org.apache.log4j.Logger;
import org.apache.log4j.xml.DOMConfigurator;

 class Main {
     private static Logger log=Logger.getLogger(Main.class);
     public static void main(String args[]) {
         DOMConfigurator.configure("lib\\log4j.xml");
         try {

             Database d = Database.open(new File("lib\\ExTables.mdb"));
            System.out.println(d.getTable("Cliente").display());

         } catch(Exception e) {
             e.printStackTrace();
         }
     }
 }

这是我的错误:

Answer 1

Commons Lang 3 不向后兼容 2.x。您必须下载 2.6。

您可能还想研究 Maven 或 Ant+Ivy 以使这种依赖关系解析更容易一些。
