Dear Karaf-Users,
I currently successfully ported an OSGI application from Karaf 2.3.3 to
Karaf 3.0.5.
Now, I wanted to port it to Karaf 4.0.3 and failed with an error being
thrown by the
karaf-maven-plugin.
To give an overview of the possibly relevant aspects:
I use Java 7 (Oracle JDK) for implementation and maven 3.3.9 for build.
The Karaf version is 4.0.3 which is also the version of the
karaf-maven-plugin I use.
I already upgraded nearly all packages that my system shares with Karaf
to the version Karaf
4.0.3 uses. I only did not upgrade my OSGI dependency to 6 since the
compilation fails.
But this is another issue and I think it should not be a problem.
I explicitly import the features of Karaf with the descriptor sequence
available for the
karaf-maven-plugin and have my own feature file using the 1.2.1 namespace:
mvn:org.apache.karaf.features/standard/${karaf.version}/xml/features
mvn:org.apache.karaf.features/enterprise/${karaf.version}/xml/features
mvn:org.apache.karaf.features/spring/${karaf.version}/xml/features
mvn:org.apache.karaf.features/framework/${karaf.version}/xml/features
file://${project.basedir}/target/classes/features.xml
The feature files of Karaf are loaded successfully - the feature openjpa
I use is located in
the enterprise features file of Karaf and is successfully found. The
descriptors are even listed
in debug mode. So they should be reachable.
I do not use http-whiteboard feature. But I assume that some cxf feature
I use does.
Nevertheless, the karaf-maven-plugin fails on the goal
features-add-to-repository in the package phase with the
following error message:
[ERROR] Failed to execute goal
org.apache.karaf.tooling:karaf-maven-plugin:4.0.3:features-add-to-repository

I looked into the standard features file of Karaf and found the feature
http-whiteboard. Thus, the maven plugin should find
it.
I even defined the http-whiteboard feature in my own features file,
nearly identically to the definition in the Karaf features but the
bundle still does not find the feature. I just removed the prerequisite
and dependency attributes from the feature elements. Moreover,
I also tried using the 1.3.0 namespace but it did not solve the problem.
Is someone able to give me a hint to a solution of my problem?
Sincerely,
Mario
