Akka failure when running integration tests in maven

Question

I've written some integration tests for a project which, when I run the service in intellij and then run the integration tests works fine, but when I run man clean verify, if causes the following error at the point that I attempt to create the SQSRestServer:

NodeAddress serverAddress = new NodeAddress("http", "localhost", configuration.getElasticMQPort(), "");
server = SQSRestServerBuilder
            .withPort(configuration.getElasticMQPort())
            .withServerAddress(serverAddress)
            .start();

The error that I get when running in maven is as follows:

[ERROR] Exception in thread "main"

Any ideas what's wrong?
