The easiest way to get started with Vaadin development is to install the Vaadin Plug-in for Eclipse. You don’t need to download or install anything else but the plug-in to your Eclipse IDE for Java EE Developers (Ganymede or newer) to start development. Learn more about the features.
To install the plugin:
Select Install New Software… from the Help -menu
install new software:
Eclipse 3.5 and newer: http://vaadin.com/eclipse
Eclipse 3.4: http://vaadin.com/eclipse/3.4
Visual Designer not available in the Eclipse 3.4 version.
Select the features you want to install and click Next to proceed with the installation.
Alternatively you can install the Vaadin Plug-in for Eclipse from the Eclipse Marketplace or you can download an offline installation package for Vaadin 6 from the Directory.
If you are looking for the latest nightly build version of the plug-in, you can use http://vaadin.com/eclipse/experimental update site.
