Feature camel-activemq not in features repository

[Ephemeris Lappis]

Hello.

I can't identify where and how the camel-activemq is defined.

I use the features repository :
<repository>mvn:org.apache.camel.karaf/apache-camel/${version.of.camel}/xml/features</repository>

with different versions, among them : 2.25.4

And the camel-feature is not found.

What's wrong in my works ?

Thanks for your help.

Regards
