Eclipse unable to resolve akka reference in maven project

I am trying the akka tutrials that remotely deploys the pi calculation. I am using the mvn project with eclipse juno. I have been able to install the maven pluggin for eclipse and successfully run the first pi claculation. Now I am trying the second pi tutorials which involves remote deployment of actors. But when I open the tutorials package in the eclipse IDE looks like some of the akka files are not been resolved by the system. I have defined the dependencies in the POM but still eclipse and maven complain. When I run the maven compile goal in the eclipse, the project gets compiled but when i try to run it it gives me error. Below are the sample code snippets. 

import akka.actor.UntypedActor; 
import akka.actor.ActorRef;
import akka.routing.CyclicIterator;
import akka.routing.InfiniteIterator;
import akka.routing.UntypedLoadBalancer;
eclipse complains that it cannot resolve the above importation

this is the POM.XML file 

<?xml version="1.0" encoding="UTF-8"?>

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

this is the error from eclipse 

Exception in thread "main" java.lang.Error: Unresolved compilation problem: 

    at Akka_Remote_Cluster.Akka.Remote.Cluster.Pi.main(Pi.java:16)

Any suggestion on what the problem is

I've fixed a similar problem with deleting and redownloading the required Maven artifacts. The first download was somehow broken.

I think you need to manually import config-0.3.1.jar from the akka distribution (inside libs)
