karaf-maven-plugin and dependent features
Hello,
I'm doing my first steps with the karaf-maven-plugin.
I created a simple bundle list with projectA and now would like project-B
to depend on project-A resulting in a dependent feature to be added in the
features.xml generated in projectB. Rather than a dependent feature I get
an entry like
<bundle
start-level="50">wrap:mvn:my.company/projectA/1.0-SNAPSHOT/pom</bundle>
Is it possible to include and reference dependent features in the pom using
their maven identification?
Cheers,
Reto

Hi Jean-Baptiste,
yes, I (and Reto) know we can use feature.xml templates. But that is not
what you want in a "POM first" project. The POM is supposed to be the single
source for dependency information, artifact declarations, etc.. Feature
dependencies are just another flavor of dependency, and it would be very
nice if the plugin could resolve them for the feature.xml artifact.
Otherwise there is duplication of project meta data, is there not? A
dependency feature is normally also a compile time dependency. At least in
my case it is. So the same dependency would have to be maintained in the POM
and the feature.xml template.
As a side question: Do you happen to know if the Camel feature.xml is
maintained manually as well? I noticed that it is incredibly "lean" and does
not state a lot of its actual dependencies. My assumption is that the
knowledge of what bundles are installed in a stock Karaf installation is
worked into that feature file.
If my assumption is correct, is there a way to pull that knowledge into a
Maven project by means of a meta-dependency? So with tool support one could
easily find out what dependencies one carries unnecessarily/are provided if
the runtime-container is Karaf?
If the assumption is wrong, how does it work?
Regards,
Ralf

Hi guys,
You can use your own features XML template.
It's what we do in Karaf: basically, when the features XML is a bit
complex, you can create it by hand.

Hi Reto,
can you provide to me an exact description of your expectations ?
I need a kind of specification to evaluate your requirements and
implement it.
For instance, a pom and an expected resulting features.xml would help.
Thanks,
Regards

Hi Ralf
Unfortunately I didn't get it to work as desired. Do you feel like opening
an issue in JIRA requesting for this feature?

Reto,
have you managed to generate the feature dependency information? I am
struggling with the exact same thing...
My understanding of the plugin ducumentation
<http://karaf.apache.org/manual/latest/developers-guide/karaf-maven-plugin-features-generate-descriptor.html>
is that by setting the property "aggregateFeatures" to false, this should
happen. But no luck here.
Thanks!
Ralf

Hi Jean-Baptiste
Yes that's exactly what I would like to have generated. I see I could add
this manually to the features.xml template but I would prefer to use the
dependency visible also to maven and use the maven tools to add and
maintain the dependency on (the maven artifact generating) "other". Is this
possible?
Cheers,
Reto

Hi,
use <feature/> inside the feature:
<feature name="my" version="1.0">
<feature>other</feature>
</feature>
You can also "share" bundle adding dependency="true".
