Deploying war files built with WebDSL produce an error in the lastest major version of Tomcat:

04-Jun-2021 08:51:56.785 INFO [Catalina-utility-1] org.apache.catalina.startup.HostConfig.deployWAR Deploying web application archive [/usr/local/Cellar/tomcat/10.0.6/libexec/webapps/conference.war]

Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
