Cannot run Errai Dev Mode with JBoss AS or Wildfly

Question

I'm trying to use Errai 3 new features which is JBoss AS integration, however I am getting this error:

[ERROR] Unable to load server class 'org.jboss.errai.cdi.server.gwt.JBossLauncher' [ERROR] java.lang.ClassNotFoundException: org.jboss.errai.cdi.server.gwt.JBossLauncher [ERROR] at java.net.URLClassLoader$1.run(URLClassLoader.java:366) [ERROR] at java.net.URLClassLoader$1.run(URLClassLoader.java:355) [ERROR] at java.security.AccessController.doPrivileged(Native Method) [ERROR] at java.net.URLClassLoader.findClass(URLClassLoader.java:354) [ERROR] at java.lang.ClassLoader.loadClass(ClassLoader.java:425) [ERROR] at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) [ERROR] at java.lang.ClassLoader.loadClass(ClassLoader.java:358) [ERROR] at java.lang.Class.forName0(Native Method) [ERROR] at java.lang.Class.forName(Class.java:270) [ERROR] at com.google.gwt.dev.DevMode$ArgHandlerServer.setString(DevMode.java:118) [ERROR] at com.google.gwt.util.tools.ArgHandlerString.handle(ArgHandlerString.java:26) [ERROR] at com.google.gwt.util.tools.ToolBase.processArgs(ToolBase.java:238) [ERROR] at com.google.gwt.dev.ArgProcessorBase.processArgs(ArgProcessorBase.java:29) [ERROR] at com.google.gwt.dev.DevMode.main(DevMode.java:310)

The POM configuration is this:

</configuration>

What could be missing here?

add this in your pom.xml

<dependency>  
 <groupId>org.jboss.errai</groupId>  
 <artifactId>errai-cdi-jboss</artifactId>  
 <version>${errai.version}</version>  
</dependency>
