Same here. @lburgazzoli wdyt?

[lburgazzoli]

I need to check how the things are defined now that we use a configmap, can you try to set the class package as etc.camel ?

[dmvolod]

@lburgazzoli I tried with package and it's working fine, but don't know why this default package?

[lburgazzoli]

It is because I've changed how the integration is given to the runtime images: before it was included as a resource, now it is on the file system and the class name is computed from the path, I need to re-think how this is computed, maybe using an env var to tell the image the base path for integrations.

Here is the culprit: https://github.com/apache/camel-k/blob/master/runtime/jvm/src/main/java/org/apache/camel/k/jvm/RoutesLoaders.java#L85-L90

This seems to be fixed.

[nicolaferraro]

Still happening...

[lburgazzoli]
