Summary: Exception java.lang.NoClassDefFoundError:
com/fasterxml/jackson/databind/JsonNode
Key: CAMEL-15752
URL: https://issues.apache.org/jira/browse/CAMEL-15752
Project: Camel
Issue Type: Bug
Components: camel-kafka
Affects Versions: 3.6.0
Reporter: Paolo Patierno
Hi,
I have an application using camel-kafka 3.4.4 (which has kafka 2.5.0 as
dependency).
When I switch to use camel-kafka 3.6.0 (which has kafka 2.6.0 as dependency), I
get the following exception.
{{020-10-24 19:23:45 ERROR KafkaThread:49 - Uncaught exception in thread

Adding the explicit dependency to jackson-databind as following solves the
problem
{code:java}
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.11.3</version>
</dependency>
{code}
As reference, this is the parent pom.xml in my project where I set camel-kafka
version (but even Kafka version, which is used in other modules).
[https://github.com/ppatierno/formula1-telemetry-kafka/blob/master/pom.xml]
and following the pom.xml of the specific application using camel-kafka (where
I have to add the jackson-databind reference for fixing the exception).
