Adding Add-On using Ivy

Hello,

I'm trying to add Vaadin Add-On to my web application. I'm using Ivy dependency manager and Ant to build. I've added dependency for the Add-On MessageBox (https://vaadin.com/directory#!addon/messagebox), Add-On was downloaded by the Ivy, it's stored in the Ivy directory, but after building and deploying project on the JBoss EAP 7.0.2 server, I got and error:

12:23:52,602 SEVERE [com.vaadin.server.DefaultErrorHandler] (default task-28) : java.lang.NoClassDefFoundError: de/steinwedel/messagebox/MessageBox

Have you used Ivy with Ant in your applications?
 

Hello,

We are working on multiple projects with Eclipse/Ivy/Ant. It's working quite well, and no troubles with addons.

Do you have some ivy-related clause in your war target ?
We use :

<copy todir="${workdir}/WEB-INF/lib" flatten="true">
            <fileset refid="ivy.deps.default.fileset"/>
        </copy>
