mvn tomcat:run doesn't start Tomcat

Question

Hi all,

I am trying to deploy and run my webapplication using maven and its tomcat plugin.

I have set it up in project's pom.xml, but when I'm calling it from command line:

mvn tomcat:run

all that I get is:

[root@ovz6022 trunk]# mvn -e tomcat:run
+ Error stacktraces are turned on.

And that's all. Tomcat hasn't been launched but I don't see any errors here.

Does anybody knows what's happening?

Answer 1

The clue is in the line:

[INFO] Skipping non-war project

The tomcat:run goal is intended to work with war projects, I'm guessing yours is a jar project.

You need to change the packaging of your project to war, you may also need to provide some additional configuration for the war to actually do anything.

Note: I'd recommend having a separate war project to your jar projects, then adding the jars as dependencies to the war.
