How to set up Maven Deploy Task in IDEA 12?

The Maven Deploy Task for my project says to use the project defaults which say to use Tomcat 7.

However, when I run the deploy task within IDEA, I get the below. What do I need to fix/change?

If IDEA is using the Project Defaults for this maven deploy task, why should I have to specify anything inside the POM file???

Confusing...

Thanks in advance.
