Teamcity - package javax.servlet does not exist

How do I import javax.servlet in Teamcity? I have the below error message when I try to build the java project through teamcity IntelliJ IDEA runner.

This is my first time with teamcity and I'm using this https://github.com/marekbruchaty/SimpleJavaWebApp project. I have a CentOS server which has teamcity and gitlab.

From my desktop, using IntelliJ IDEA I can import servlet.api to do a successful build. But the teamcity is in another location and managed remotely and I wonder how to import the servlet-api into teamcity?

Where should I add the servlet-api.jar as a dependency in teamcity so it can compile?

Here is the build error:
