我在尝试使用Jetty和Intellij idea运行它时遇到以下错误

在尝试查看错误消息时,我了解到错误可能是由于添加模板引擎时出错造成的。但是我试了好几天都没能修好。请帮助问题可能是您混用了不兼容的版本。您可以通过运行以下命令来检查您的版本:
mvn dependency:tree
(如果您有Eclipse,您可以打开pom文件并切换到“Dependency Hierarchy”(依赖层次结构)选项卡进行相同的操作。)
特别检查以下各项:
- org.thymeleaf:thymeleaf-spring4:jar
- org.thymeleaf:thymeleaf:jar
这两个版本应该是相同的。如果没有,请调整依赖项。问题可能是您混合了不兼容的版本。您可以通过运行以下命令来检查您的版本:

错误。请运行maven update并重试您有哪些Thymeleaf依赖项/jar文件?我使用maven依赖项进行配置。我将把它们作为编辑放在question@holmis83在中添加了依赖项question@AjitSoman已经做了几次了,你已经得到了java.lang.NoClassDefFoundError
