Camel-K Java native support - native run of a java route fails

[catshout]

I've a fresh installed Camel-K 1.8.0 Operator. My sample route hello.java like

from('timer:tick?period=3000')
  .setBody().constant('Hello world from Camel K')
  .to('log:info')

and tried to execute the following command

kamel run -t quarkus.package-type=native hello.java

With this I'm getting the error (excerpt from resource yaml

  status:
    conditions:
    - firstTruthyTime: "2022-02-18T07:43:59Z"
      lastTransitionTime: "2022-02-18T07:43:59Z"

What am I missing here?

I think we don't support Java because the joor dependency. @astefanutti can you confirm please?

[astefanutti]

Right, native compilation is currently supported for YAML and XML integrations, as well as Kamelets.

Thanks for your replies.

1. Will the Java native compilation supported in one of the next releases (may be w/o joor support)?
2. Can locally native compiled Java routes being used for Camel-K deployment?
3. If using YAML native compiled, could the compiled resource be moved from one environment (e.g. DEV) to another (e.g. TEST) without re-compile again?

Background of this the significant reduction of memory footprint and startup time of native compiled resources. That's in my mind the real advantage for mass micro services.

Hi @squakez and @astefanutti, the topic of a native compiled resource came up today again. Are there any plans to enable this for Java based Camel-K Integrations? Thanks for a hint ..

Hi @squakez and @astefanutti. Could this also be turned into a feature request? Thanks in advance for your thoughts.
