Would this be possible to remove Lombok to keep the example un-opinionated?

[dweber019]

Yes sure. @davsclaus what do you think as you explicitly asked for it in the issue comment.

[oscerd]

LGTM, but I think we should maintain examples in a separated repository like we have here: https://github.com/apache/camel-k-examples

Or if we don't want to have it separated, we need to discontinue the repository.

[dweber019]

@oscerd @astefanutti @davsclaus do you need any assistance from my side?

[oscerd]

I think we have everything we need, eventually we'll move the example in the other repo, but for the moment it's all ok. Lets wait for @astefanutti and @davsclaus :-)

[astefanutti]

Shouldn't it be // camel-k: resource=file:./target/pojo-jar-1.0.0.jar?

[davsclaus]

Yes can we avoid all these weird parent folder?

[dweber019]

I did run the command like this and it worked. I think as it's defined as modeline the cwd/pwd is the java file I define in the kamel command. README => kamel run ./src/main/org/apache/camel/OpenApiRoute.java
So kamel changes the execution location to ./src/main/org/apache/camel/OpenApiRoute.java

[astefanutti]

Ah right, the resources are resolved relative to the current file location.

[astefanutti]

Yes, I agree we can have it merged here and continue the discussion about examples location in a larger context.

[davsclaus]

Only nitpick is those ../../../ folder names. If the JAR is in the target folder then grab it there.

[astefanutti]

I think this is good to go. Thanks!
