2. run Maven command:

   mvn dependency:tree | grep tomcat

   
   Example console output (Tomcat dependencies):

   [INFO] |  +- org.springframework.boot:spring-boot-starter-tomcat:jar:3.0.0-RC2:compile
   [INFO] |  |  +- org.apache.tomcat.embed:tomcat-embed-core:jar:10.1.1:compile
   [INFO] |  |  +- org.apache.tomcat.embed:tomcat-embed-el:jar:10.1.1:compile
   [INFO] |  |  \- org.apache.tomcat.embed:tomcat-embed-websocket:jar:10.1.1:compile

   Used Tomcat version: 10.1.1

mvn dependency:tree command

In this section, we use mvn dependency:tree command on Spring Boot 3 project to show how dependencies looks. The command prints dependencies as tree.
