Maven tomcat7:run失败，因为tomcat7:RunWar只起作用

我有一个简单的（REST）web应用程序，当我运行mvn tomcat7:run时会抛出以下错误：， mvn tomcat7可以正常工作的地方：仅运行war

对于如何解决此问题或如何进一步调试此问题的任何帮助，我们将不胜感激

感谢和问候，

在我的例子中，发生这种情况是因为来自jetty的依赖关系。stacktrace不清楚，但在调试tomcat插件时可以找到

使用

mvn dependency:tree

查看模块的maven依赖项，并查找

servlet api

可传递依赖项。一旦找到，就从构建中排除它。
