maven + thymeleaf 无法实例化bean错误记载

最近公司新开项目 想练点新技术，于是乎选用了thymeleaf做前台 jsp做后台，IDE选用的是IDEA，(就是这么智能的IDE导致我两天都在查这个错误)

但是在配置环境的过程中tomcat启动无限报

错误: BeanCreationException
错误描述：
Error creating bean with name 'templateEngine' defined in URL [file:/C:/Users/chuan/Desktop/jshShow/target/jshShow/WEB-INF/classes/springMVC-servlet.xml]: Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class org.thymeleaf.spring4.SpringTemplateEngine
错误信息：

百度 google翻遍前十页也没找到错误原因，以为是thymeleaf配置解析视图错误，贴下代码

原配置：

<!-- thymeleaf视图 -->
    <bean id="templateResolver"
          class="org.thymeleaf.spring4.templateresolver.SpringResourceTemplateResolver">
        <property name="prefix" value="/WEB-INF/templates/" />
        <property name="suffix" value=".html" />
        <property name="templateMode" value="HTML5" />
    </bean>

    <bean id="templateEngine"
          class="org.thymeleaf.spring4.SpringTemplateEngine">
        <property name="templateResolver" ref="templateResolver" />
    </bean>

    <bean class="org.thymeleaf.spring4.view.ThymeleafViewResolver">
        <property name="templateEngine" ref="templateEngine" />
    </bean>

修改各种版本包括thymeleaf官网的xml配置，代码如下：

!-- Thymeleaf View Resolver - implementation of Spring's ViewResolver interface -->
    <bean id="viewResolver" class="org.thymeleaf.spring4.view.ThymeleafViewResolver">
        <property name="templateEngine" ref="templateEngine" />
        <property name="characterEncoding" value="UTF-8" />
    </bean>
    
    <!-- Thymeleaf Template Engine (Spring4-specific version) -->
    <bean id="templateEngine" class="org.thymeleaf.spring4.SpringTemplateEngine">
        <property name="templateResolvers">
            <set>
                <ref bean="templateResolver" />
            </set>
        </property>
    </bean>
    
    <!-- Thymeleaf Template Resolver -->
    <bean id="templateResolver" class="org.thymeleaf.spring4.templateresolver.SpringResourceTemplateResolver">
        <property name="prefix" value="/WEB-INF/templates/" />
        <property name="templateMode" value="HTML" />
    </bean>

无论哪个配置文件 最后报错的原因都是

无论修改什么配置最底层错误都是无法实例化Bean,单独使用Jsp视图配置时就可以正常启动，万般查询无果(jdk版本，spring版本，配置文件，加载顺序，thymleaf版本等等)，只能对着网上的配置文件一点一点删除修改，无聊怎么改，都是统统报错，最后莫名其妙看了一眼pom.xml配置文件发现idea的pom.xml配置文件自动生成了一个：

虽然不明白到底是什么意思 但是删除后thymeleaf配置文件正常跑通，晚上回去看看一看这里面到底是做什么的
