Eclipse

Working example project, which results from this tutorial, can be downloaded from github.com/vaadin-on-grails/quickstart-app.

Spring provides great tool Groovy/Grails Tool Suite for development of Groovy and Grails based projects. If Eclipse is your development IDE, you should definetelly get GGTS.

We will show how to create a new Grails project with Vaadin using GGTS in this article.

Step 1

Search for Grails type of project in New Project wizard and click on Next.

Setup Grails

Step 2

Type a name of the project and click on Finish.

Setup Grails

Step 3

Open file BuildConfig.groovy and add Vaadin plugin compile ":vaadin:7.6.1".

Setup Grails

The latest version of the plugin is always available on http://grails.org/plugin/vaadin

Run grails compile to reload dependencies. Click on Grail icon in GGTS and type there compile.

Setup Grails

Then run grails vaadin-quickstart that will generate sample code to easier project configuration.

The command vaadin-quickstart will generate MyUI.groovy and remove URL mapping inside UrlMapping.groovy.

Optional

We have to disable Grails to take control over the URLs, so Vaadin can do it instead. Open UrlMappings.groovy file and make sure the URL mapping is empty, so the content of the file is the following.

Setup Grails

Step 6

Click on Grail icon again and run run-app command.

Setup Grails

Step 7

Now your application is running on http://localhost:8080/my-app
