java - (Maven项目)无法找到或加载主类 "class"

Question

我正在遵循 Spring 教程，一切都工作正常，直到我克隆我的项目，现在克隆的项目和原始项目不想工作，我已经搜索了整个堆栈溢出类似的问题，但我无法解决这个问题，我已经清理了项目，重新启动了 Eclipse，更新、添加和删除了 pom.xml 中的依赖项，但似乎没有任何效果。

这是我的主类(class):

    package com.caveofprogramming.spring.test;

import java.util.ArrayList;
import java.util.List;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.caveofprogramming.spring.test.Offer;
import com.caveofprogramming.spring.test.OfferDAO;


public class Tester {

    public static void main(String[] args) {



        ApplicationContext context = new ClassPathXmlApplicationContext(
                "com/caveofprogramming/spring/test/beans/beans.xml");

        OfferDAO offersDao = (OfferDAO) context.getBean("offerDao");



        try {

            List<Offer> offers= new ArrayList<Offer>();
            offers.add(new Offer(1,"Pepito", "pepito@tcs.com", "i know css and html5"));
            offers.add(new Offer(2, "Juancito", "juancito@tcs.com", "i know about rest and play"));
            offers.add(new Offer(3, "Juancho Tazo", "jtazo@tcs.com", "im an expert on SPEL and SQL!"));

            if(offersDao.Create(offers).length==offers.size()){

                for (int i = 0; i < offers.size(); i++) {

                    System.out.println(offers.get(i).getName()+" record was created succesfully");

                }

                System.out.println("All the new records were created succesfully");

            }

            else{
                System.out.println("One or more of the records were not createdS");
            }

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

        ((ClassPathXmlApplicationContext) context).close();

    }

}

正如我所说，当我将项目复制粘贴到同一工作区时，一切都开始失败，当然我更改了名称。

这个错误是我在执行 Maven clean 之后得到的。

如果我不这样做，我会收到错误:

如您所见here它是从4.2开始添加的，尝试将pom.xml中的所有spring依赖项更新为4.2.5.RELEASE。
