IntelliJ IDEA setup

I am a newcomer to Vaadin and will have an attempt to replace some old PHP-sites with a Vaadin-based web application. I wanted to use my favorite Java IDE, but did not find much information on how to setup a project in IntelliJ IDEA. And since switching back to Eclipse is not an option, I had to figure it out myself

I managed to get a simple HelloWorld application running, and will describe here the steps I took so other newbies like me won't have to figure it out them self.

Since I am quite new to creating Java-based web applications, feel free to suggest improvements on my project setup.

1) Download the Vaadin JAR
2) If not already done, install a Tomcat server
3) Start IntelliJ and create new project from scratch ( all steps below are performed with IntelliJ 9 )
4) Type of project is Java Module and as desired technology you select Web Application. This will create the web folder, including the WEB-INF dir and a web.xml file
5) Create a web/WEB-INF/lib folder and place the Vaadin JAR into that folder
6) Goto Project Structure | Modules and let your module depend on the Vaadin JAR. Mark it as export
7) Create a HelloWorld class and adjust your web.xml file, as described in the book of Vaadin
8) To run/debug, create a new "Tomcat Server" configuration. If not yet present, configure a Tomcat server by providing the link to the installation dir of your Tomcat server

This should do it (at least, it was sufficient for me)

JetBrains just released plugin for IntelliJ IDEA to support Vaadin:

Take a look.

Maybe you want to post the question to http://youtrack.jetbrains.com/issue/IDEA-75348 to ensure that the author knows about the issue.

Update on this old thread, as of 2017-04 using IntelliJ 2017.1 with Vaadin 8…

See my recent thread: 
https://vaadin.com/forum#!/thread/15360111

The upshot:

  • The plugin for Vaadin bundled with IntelliJ seems to be not working. Also seems to be outmoded as the Vaadin team moves to a pure Maven approach.
  • Creating a new project using a Maven archetype *within* IntelliJ creates a use POM file that is nearly empty. No go.
  • Instead, install and use Maven at the command-line to create a new project. Then import into IntelliJ.
