Tomcat Plugin: How does Intellij build the artifact to deploy?

I have a (somewhat complicated) multiproject build that produces numerous WAR and EAR files.  When I setup a Local Tomcat deployment using the Tomcat Plugin and in my "Select Artifacts to Deploy" box, I see all the WAR and EAR files that my gradle build is capable of producing.  I select the one I want and deploy, but the WAR file is somewhat different than what I get when I use gradle command line to produce the WAR.  How can I confirm what Intellij is doing to produce the selected artifact?  It seems like it would just use the gradle target but I'm wondering if Intellij is owning some or all of the process and not doing the exact same stuff that my gradle scripts do.
