Error with deployment of vaadin servlet (using vaadin CDI) in wildfly

Question

I'm trying to deploy a war based on vaadin CDI in wildfly 11 (from within eclipse) but I have the following error:

21:14:36,578 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-2) MSC000001: Failed to start service jboss.undertow.deployment.default-server.default-host."/myapp-1.0-SNAPSHOT".UndertowDeploymentInfoService: org.jboss.msc.service.StartException in service jboss.undertow.deployment.default-server.default-host."/myapp-1.0-SNAPSHOT".UndertowDeploymentInfoService: java.lang.ClassNotFoundException: com.vaadin.cdi.internal.VaadinCDIServlet from [Module "deployment.myapp-1.0-SNAPSHOT.war" from Service Module Loader]

It seems to have problems to get VaadinCDIServlet class. These are my dependencies in pom.xml

<dependencies>
    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-web-api</artifactId>
        <version>8.0</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>com.vaadin</groupId>
        <artifactId>vaadin-server</artifactId>
    </dependency>
    <dependency>
        <groupId>com.vaadin</groupId>
        <artifactId>vaadin-push</artifactId>
    </dependency>
    <dependency>

        <artifactId>vaadin-client-compiled</artifactId>
    </dependency>
    <dependency>
        <groupId>com.vaadin</groupId>
        <artifactId>vaadin-themes</artifactId>
    </dependency>
    <!-- The following 2 are necessary to vaadin CDI -->
    <dependency>
        <groupId>com.vaadin</groupId>
        <artifactId>vaadin-cdi</artifactId>
    </dependency>
    <dependency>
        <groupId>javax.enterprise</groupId>
        <artifactId>cdi-api</artifactId>
        <version>1.2</version>
    </dependency>
</dependencies>

I have an empty beans.xml file under WEB-INF. Anyone has idea of what I'm missing?

Your CDI api should be in "provided" scope, having it in default scope may cause odd issues.

I suggest to bootstrap your project with the Viritin CDI archetype, then you get all stuff right from the beginning.

Have you remembered to remove VaadinServlet from your main UI class?
