--------------------------------------------------------------------
The problem is that there are two classloaders involved:
* one is the app classloader containing JARs being part of {{-classpath}}
prepared by JBang itself - this involves all transitive dependencies of the
{{DEPS}} specified in {{dsl/camel-jbang/camel-jbang-main/dist/CamelJBang.java}}
* the other one is
{{org.apache.camel.main.download.DependencyDownloaderClassLoader}} prepared for
the camel context created for {{jbang camel run}} command.
camel-kamelet-utils was not seeing the amazonsdk jars, because of two different
classloaders.
When I removed {{org.apache.camel.kamelets:camel-kamelets-utils}} from
{{main.CamelJBang}} and added it to the route itself:
{code:yaml}
# camel-k: dependency=mvn:software.amazon.awssdk:dynamodb:2.17.290
# camel-k: dependency=mvn:org.apache.camel.kamelets:camel-kamelets-utils:0.9.0
- route:
from:
uri: "kamelet:kafka-not-secured-source"
...
{code}
everything worked fine.
