web.xml is missing and ＜failOnMissingWebXml＞ is set to true
maven项目中pom.xml文件报错：web.xml is missing and is set to true，原因是项目生成时未生成web.xml文件。解决办法：①点开项目文件夹，点击Deployment Descriptor，选择Generate Deployment Descriptor Stub选项，然后项目会自动在src/main/webapp/WEB_INF文件加下创建web.xml文件。错误解决。②点击项目，右键选择Properties，–>Project
