title: mvn tomcat:run - change default maven tomcat port
body: <p>Trying to follow Spring roo tutorial steps I perform:</p>
  
  <pre><code>$ mkdir sample
  $ cd sample
  $ roo
  roo&gt; script --file filename.roo
  roo&gt; quit
  $ mvn tomcat:run
  </code></pre>
  
  <p>and when I launch  <code>mvn tomcat:run</code> I get hanged up console on <code>INFO: Starting Coyote HTTP/1.1 on http-8080</code> because this port is busy. Where can I change 8080 port to another one(I tried to change tomcat port, didn't find anything in the maven folder , .m2 folder and in the project folder)?
  Thanks in advance for any help.</p>
