[rabbitmq-discuss] RabbitManagement from Berico - Technologies is not working

[Rom Cabral]

Hi guys,

Just asking if anyone here tried using the library from Berico Technologies 
from https://github.com/Berico-Technologies/RabbidManagement. I tried using 
it but encounters the error below. It seems to me that there is null 
pointer exception somewhere. I tried to call the initialize explicitly but 
still got the error. Do I need to add on my project other than dependency 
and repositories on my pom.xml?

   test code:
   RabbitMgmtService service = RabbitMgmtService.builder().build();
        //service.initialize();
        service.queues().create(new Queue("test-queue"));
        Assert.assertEquals("test-queue", 
service.queues().get("test-queue").get().getName());
