As explained in https://issues.jboss.org/browse/JBIDE-16341 you should remove <webXml>src/main/webapp/WEB-INF/web.xml</webXml> which basically overwrites the filtered version published to your server.
You must also make sure your project's .settings/org.eclipse.wst.common.component doesn't contain <wb-resource deploy-path="/WEB-INF/web.xml" source-path="/src/main/webapp/WEB-INF/web.xml"/>
Another option is to delete the project .classpath, .project and .settings/ before importing it in eclipse
Thank you very much. I always use Import --> Maven --> Existing Maven Projects
