spring config server not posting to rabbitmq - spring-boot

Question

I've generated a spring boot config server from spring's initialzr.
I've installed rabbitmq with brew. initialzr generated with boot version 2.1.1.RELEASE and cloud version Greenwich.M3.
the simple rest services are connecting to rabbitmq queues. the config server is connection to a gitlab config repo.
But when I commit and push a change to it, the change is not reflected by the service application. The config server gets logs messages when the push is completed. Can anyone say what might be wrong? No messages ever seem to appear in rabbitmq console. I have been able to refresh the properties via actuator/bus-refresh through rabbitmq though.
config-server log messages on commit of change to config-repo's employee-service.yml file:

Try to create and build your project with Maven instead of Gradle.
I experience the same problem. I have two identical apps with the same RabbitMQ dependencies, one is build with Maven and second with Gradle. The Maven-based app publishes things to RabbitMQ as expected. The very same app, built with Gradle doesn't establish connection to RabbitMQ and is not publishing events.
To further clarify things, I run both apps in Eclipse with Spring Tools.
