我被困住了，我无法编译我的spring boot vaadin项目用于生产。 这是我的pom.xml：

这是我正在使用的maven命令：
mvn -Pvaadin.productionMode clean vaadin:prepare-frontend vaadin:build-frontend package
这是输出：

我没有其他想法了，这是怎么了。 我在这里尝试了说明： https://vaadin.com/docs/flow/production/tutorial-production-mode-basic.html 但是'executions'标签使maven失败了。 摘录来自这里： https://github.com/vaadin/flow-spring-examples/blob/master/pom.xml
原始{甚至不工作的）pom.xml是从https://start.spring.io/生成的
我认为我的pom.xml缺少某些内容，但我不知道是什么。 有人使用Spring Boot和vaadin运行了pom.xml吗？
重新阅读并尝试删除和添加插件后，我认为错误是此行： ''' 错误：无法解析“ @ vaadin / flow-frontend / Flow” ''' 为什么不编译以及如何编译？
