使用 vaadin 构建 Maven 项目的 WAR 文件

Question

我正在尝试为我的 Maven 项目构建一个 WAR 文件，我在其中使用了 vaadin 框架。当我在 eclipse 中运行项目和 jetty:run 项目运行s 顺利。但是当我尝试创建一个 WAR 文件并将其部署到 Apcahe Tomcat 10 时，我收到 404 Not Found 错误。当我在线搜索几乎所有关于 index.jsp 文件的解决方案时，但我的项目中没有 index.jsp 文件。打包 WAR 添加到我的 pom.xml 文件中。在mavens站点中，正确的maven目录显示如下

但是我的目录和这里的不一样。我没有 web.xml 和 index.jsp 文件。可能是因为 vaadin 框架，但我找不到部署项目的方法。谁能帮我解决这个问题？

谢谢。

我的 pom.xml 文件看起来像这样。

感谢@PiotrP.Karwasz 我将 tomcat 版本从 Tomcat 10 降级到 Tomcat 9 并解决了问题。
