IntelliJ Idea 2017 - Maven archetypes list doesn't populate on new project

I'm attempting to create a new Vaadin project using the Maven vaadin-archetype-application archetype, but when I select "Maven" from the left panel on the first new project window, the right pane displays "Loading archetype list..." with a loading spinner, but the list never populates.

I've created Vaadin projects using the Maven archetype before, in IntelliJ 14, but this is my first new Maven archetype project since upgrading. Is there something I need to do to import my archetypes into IntelliJ 17?
