Eclipse Tomcat resources Available list doesn'

I am trying to configure my GWT 2.7.0 app built with maven to work with Tomcat7 server inside the Eclipse IDE.

My project, here is link compiles and run fine in Tomcat server from linux console using maven. Here is how I run:

In first linux shell:

mvn clean install
mvn tomcat7:run-war-only

And in second shell:

mvn gwt:run -pl web

Add Tomcat resources window:

My project gwt_2.7.0_maven_eclipse is not there. I do not understand why.

Here is my main pom.xml:

Can any one of You help me with it? I struggle with it for few day, and cannot make it work.

Edit

Here is my first project structure in Eclipse IDE

After some reading I've executed in linux shell: mvn eclipse:eclipse, which had rebuild my single app project into multi project (by project I meen Eclipse project). In the result of that I've got this structure:
