Description

Hello,

As far as I can tell from the documentation and from several tries the karaf-maven-plugin is unable to correctly process karaf features that contain configuration blocks with classpath URLs, i.e.:

    <feature name="sling" version="${project.version}">
        <config external="true" name="org.apache.sling.serviceusermapping.impl.ServiceUserMapperImpl.amended~sling-auth-core">classpath:org.apache.sling.serviceusermapping.impl.ServiceUserMapperImpl.amended~sling-auth-core.cfg.json</config>
    <!-- ... -->
    </feature>

If the feature "sling" is either a boot or startup feature (or referenced from one such feature) the build process always fails with this kind of message:

[ERROR] Failed to execute goal org.apache.karaf.tooling:karaf-maven-plugin:4.4.5:assembly (default-assembly) on project sling-overlays-distro: Unable to build assembly: Error:
[ERROR]     Error downloading classpath:org.apache.sling.serviceusermapping.impl.ServiceUserMapperImpl.amended~sling-scripting.cfg.json
[ERROR] -> [Help 1]

The only work around that works is to use config blocks with only felix cfg notation as JSON blocks are not converted to JSON files correctly (i.e. https://github.com/apache/karaf/pull/1725/ does not appear to work correctly) and factory configurations when using the new ~ notation appears also to be broken.

What am I doing wrong?

Best regards

PS: For reference just clone the Sling Karaf stuff:

• https://github.com/apache/sling-org-apache-sling-karaf-configs
• https://github.com/apache/sling-org-apache-sling-karaf-features
• https://github.com/apache/sling-org-apache-sling-karaf-distribution

And on the POM of this last one just move for example the sling feature from installed to boot.
