This would be caused if maven is not aware of where the web.xml file is located.
If you follow the standard maven directory structure as
src/main/java src/main/resources src/main/webapp
You would have to copy the contents of WebContent [WEB-INF AND META-INF] to src/main/webapp folder – there maven would get it as expected.
