Find out what theme I'm using

Hi guys, pretty new to vaadin. I’ve just created a vaadin application, the simplest one you can create, and I was wondering, how do I find out if I have a theme in it and if so, which theme is it? The reason for that is that I’m deploying my application to Jenkins which doesn’t seem to like something in my pom.xml file and I had to comment it out:

<!--<goal>compile-theme</goal> -->

With this commented out Jenkins does the build but I’d like to know whether it is safe to do so.
thanks

Use the debug-window: https://vaadin.com/docs/-/part/framework/advanced/advanced-debug.html

Oh right, excellent, thank you for the suggestion!
