java.util.concurrent.ExecutionException：无法初始化组件

Question

我正在为Maven Web应用程序工作，我正为这个错误而苦苦挣扎，但找不到任何解决方案：

它来自运行一个index.jsp页面，该页面导入了多个其他类：

<%@page import="java.util.ArrayList" %>
<%@page import="java.util.List" %>
<%@page import= "java.net.URL" %>
<%@ page import="models.Chapter" %>
<%@ page import="models.User" %>
<%@ page import="models.Student" %>
<%@ page import="models.Teacher" %>
<%@ page import="models.Enrolment" %>
<%@ page import="dao.UserDAO" %>
<%@ page import="dao.StudentDAO" %>
<%@ page import="dao.TeacherDAO" %>
<%@ page import="dao.ChapterDAO" %>
<%@ page import="dao.Chapter2DAO" %>
<%@ page import="dao.EnrolmentDAO" %>
<%@ page language="java" contentType="text/html; charset=US-ASCII" pageEncoding="US-ASCII"%>

从到目前为止的发现来看，它说某些JAR文件可能已损坏，因此我只是从我的lib文件中删除了它们。之后，我遇到了类似Java error: Only a type can be imported. XYZ resolves to a package的错误，但我也无法解决，只是将我发送回去，将所有jar添加到WEB-INF的lib文件夹中。我尝试删除我的存储库，然后再次进行Maven安装，但没有成功。我检查了罐子和所有东西的版本，尝试了很多东西，但到目前为止似乎没有任何效果。这是我的pom.xml供参考：

 <properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
 <java.version>1.8</java.version>
  </properties>

这是我在Eclipse中的项目结构：

您是否知道我该如何处理？我真的不知道问题出在哪里。

如果您查看以下异常堆栈跟踪信息，

  

由于：java.lang.IllegalArgumentException：   java.util.zip.ZipException：打开zip文件时出错

这意味着，从部署角度来看，war文件不合适。此外，您还必须在Maven中创建 war 包装。除此之外，您还必须使用Maven War插件。您还必须在Eclipse中制作一个完整的Web项目。我建议您通过以下教程来了解一下。
