WSO2 service bundle ignoring web application dependencies

I am using WSO2 Developer Studio and currently have a Web Application and WSO2 Composite Application Project. The Car project contains a web application as a dependency. I have also included the tile dependency to the maven mom file of my web app with scoped how to "compile"

The problem I am facing now is that when I do Maven -> Install in my web application, the war file generated in the target folder contains all the slab-related jars in the lib folder under WEB-INF section. But when I try to deploy the car file to the WSO2 app server, the generated war file does not contain the required libraries and hence my war file is not deployed.

Is there something I am missing?

Update

Below is the pom.xml. I use
