I am using AWS SQS for the first time. I work in certain company which blocks us via firewall to connect from our local network to SQS for some reasons beyond my control. I can upload anything I have developed to our TomCat in AWS or even run via our Linux command line with our ec2-user (upload via WinSCP and trigger via Putty).
Since I need to provide certain solution using sqs but I can't debug accessing it from my Eclipse I am interested to mock sqs. Additionally, I see advantages on such approach from test perspective. That said, after few hours searching I found exactly what I need: http://www.schibsted.pl/blog/mocking-amazon-sqs-with-elasticmq/
I downloaded the example (https://github.com/JanGurda/elastc-mq-rule-sample) but I can't start it. I understand that there is an elasticmq embbeded which should be started together with such jar. I tried other way by downloading the elasticmq and started it before running the sample but I am still getting the same output.
Basically, I am getting this output
usage: java -jar project.jar [-h] [-v] {server,check} ...
positional arguments:
{server,check} available commands
optional arguments:
-h, --help show this help message and exit
-v, --version show the application version and exit
It seems I am doing something very silly but I didn't find a north. PS. I checked and the pom has lombok and elasticmq properly settup.

Demetrio,
The error you get is simply standard output of Dropwizard. You should use “server” parameter to start Dropwizard application. So command you use to start Dropwizard is
java -jar <> server.If you however would like to run sample integration test (which I discussed in my article) just use Maven. Type
mvn clean install. It’ll build project and run integration test.Thanks
