IntelliJ IDEA 2017.3 Help

Getting Started with Vaadin

This feature is only supported in the Ultimate edition.

IntelliJ IDEA lets you create and manage projects using Vaadin framework that optimizes your Web application development. Note that before you start creating your project you need to make sure that Vaadin SDK is downloaded on your computer and Vaadin plugin is enabled in IntelliJ IDEA.

Creating Vaadin project with Project Wizard

  1. Open Project Wizard, under Java Enterprise select Vaadin framework.
    vaadin new project
  2. Specify the following settings:
    • Project SDK - specify your project SDK.
    • JavaEE version - specify the version of JavaEE or use the default option.
    • Application Server - specify the application server or use the default server. IntelliJ IDEA creates a run configuration for your Vaadin application.
    • Version - for IntelliJ IDEA 13 and later, you can choose either Vaadin 6 or 7 version.
    • Vaadin distribution - enter the location of Vaadin installation on your machine.
      If Vaadin is not installed, then the warning message with the appropriate link appears. Click the link, download "All-in-One Archive" ZIP file and unpack it to the desired location.
    • Create sample application - select this checkbox to either enter the name of the sample application or use the default name.
  3. Click Next.
  4. Specify your project information and click Finish.
