Camel-quartz fails on Quarkus because of missing (optional) camel-cron dependency

[nicolaferraro]

I'm running the following route on camel-k with Quarkus JVM runtime:

from('quartz:trigger?cron=0/1+*+*+*+*+?')
    .routeId('groovy')
    .setHeader("m").constant("string!")
    .setBody()
        .simple('Magic${header.m}')
    .to('log:info?showAll=false')

The integration fails with:

The camel-quartz component in Camel has optional dependency on camel-cron, but while this works on a plain runtime, it fails on Quarkus (JVM).

Sounds like apache/camel-quarkus#1195. It'll be fixed in camel-quarkus 1.0.0-CR1.

Cool, we can close this one.
