Installing and Configuring IntelliJ IDEA
The Ultimate Edition
The Ultimate Edition includes built-in support for creating Vaadin applications and running or debugging them in an integrated application server.
Community Edition
You can create a Vaadin application most easily with a Maven archetype and deploy it to a server using a Maven run/debug configuration.
You can get the both editions from the website at jetbrains.com/idea.
To run a Vaadin application during development in the Ultimate Edition of IntelliJ IDEA, you first need to install and configure an application server that is integrated with the IDE. The edition includes integration with many commonly used application servers.
In the following, we configure Apache Tomcat:
Select Configure › Settings.
Select IDE Settings › Application Servers.
In the Tomcat Server dialog, specify the home directory for the server.
Click OK.
Review the application server settings page to check that it is OK.
