On Windows You can add the Maven archetype for Vaadin to IntelliJ IDEA the following way:
Open:
c:\Users\username\.IdeaIC2017.3\system\Maven\Indices\UserArchetypes.xml
and add the line:
<archetypes> <archetype groupId="com.vaadin" artifactId="vaadin-archetype-application" version="8.3.2" /> </archetypes
Now you can create a new Vaadin project via Maven
