Lukas Roedl commented on KARAF-1223:
------------------------------------

Maybe let me just explain my setup:
I've a multi-module project - 2 of this modules consist of only one features 
file (one of them describes the "core" features and the other one the 
"examples" features).
A third module is the "framework" (with Karaf and dependencies to the other 
modules, the "deploy" folder should contain the two kar files in the end).

The Problem:
What I want to do is to generate 2 separate kar files (one for "core and the 
other one for the "examples"). If I do this (in the pom of the "framework") via 
the karaf-maven-plugin with 2 executions configured and relative path 
references to the two features files I get the two desired kar files. When I 
now start Karaf both kar files are deployed to the local Karaf repo but because 
the both kar files contain the features descriptor with the same 
groupId/artifactId the "last" kar file deployed overwrites the feature 
descriptor of the previous ones. The problem is that the plugin takes the 
groupId/artifactId of the pom for the groupId/artifactId of the features 
descriptor. I already discussed this issue some days ago 
http://irclogs.dankulp.com/logs/irclogger_log/karaf?date=2012-02-21,Tue#l101

My solution now was to allow the karaf-maven-plugin to accept also mvn:* urls 
for the featuresFile property and resolve the "real" groupId/artifactId in such 
cases.

But maybe there is a better/cleaner solution for my problem?
What do you suggest?

> The features-create-kar goal of the karaf-maven-plugin plugin currently only 
> supports references to local feature files. The featuresFile tag should also 
> support mvn:* urls.
> This may also avoid the following problem if the features file is added with 
> the correct groupId/artifactId.
> In a single pom the karaf-maven-plugin with goal features-create-kar is 
> executed twice to generate two separate kar files from two independent 
> features.xml files.
> The resulting kar files are deployed to the "deploy" folder and at Karaf's 
> startup it seems that only one of them is loaded.
> The plugin adds the feature files with the same groupId/artifactId to the kar 
> files and while deploying they overwrite each other.
