I get this error when trying to compile a Vaadin WAR:

    Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.1.1:war (default-war) on project testvaadin-web: Error assembling WAR: webxml attribute is required (or pre-existing WEB-INF/web.xml if executing in update mode) -&gt; [Help 1]

I know this error means that maven cannot find my web.xml, but in the &quot;Book of Vaadin&quot; it says that **web.xml is not needed** when using Servlet API 3.0 and the Annotation `@WebServlet` in your UI class. 

I am compiling my widgetsets in a separate profile (according to [this](http://bluegulf.wordpress.com/2012/10/18/tutorial-of-setting-up-eclipsemavenvaadinjetty-project-ide-2/) guide) and it compiles fine when I rnu this profile. However, when I compile only the web-project, I get above mentioned error.

What gives?

Do I override the maven behaviour somehow? Vaadin didn&#39;t even create a WEB-INF directory. I guess I could create WEB-INF folder and keep a &quot;ghost&quot; web.xml in there to keep maven happy, but that doesn&#39;t seem right. 

Am I missing something?

Does anyone know a good solution to this?
