-------------------------------------
Summary: camel-spring-rabbitmq - RabbitMQ consumer not consuming
messages anymore
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
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:
