> Key: CAMEL-23422
> URL: https://issues.apache.org/jira/browse/CAMEL-23422
> Project: Camel
> Issue Type: Bug
> Components: camel-spring-rabbitmq
> Affects Versions: 4.18.1
> Reporter: Michael Weiss
> Assignee: Federico Mariani
> Priority: Minor
> Fix For: 4.18.3
>
>
> In 4.18.1 Spring RabbitMQ consumer does not consume messages from RabbitMQ
> anymore.
> It works in camel-jbang 4.18.1 but not in an exported camel-main maven
> project.
> Maybe this is related to how maven project is built. There is a difference in
> pom.xml and CamelApplication.java between 4.18.0 and 4.18.1, see diff below:
