Karaf 4.0.0 and Integration Tests

[Serge Huber <sh...@jahia.com>]

Hello Karaf-ers,

I am trying to setup integration tests using Karaf 4.0.0 and I’m basing my code on the itests project in the Karaf source code. 

I was having an issue at startup that looked like this : 

-------------------------------------------------------

It took me a while to track down the origin of this problem until I realized that the problem comes from the apache-karaf-4.0.0.tar.gz itself ! Specifically the etc/org.apache.karaf.features.cfg file contains the following hardcoded path : 

featuresRepositories = \
    file:/x1/asf/karaf/k40x/target/checkout/assemblies/apache-karaf/target/assembly/system/org/apache/karaf/features/framework/4.0.0/framework-4.0.0-features.xml, \
    mvn:org.apache.karaf.features/enterprise/4.0.0/xml/features, \
    mvn:org.apache.karaf.features/spring/4.0.0/xml/features, \
    mvn:org.apache.karaf.features/standard/4.0.0/xml/features

It’s not entirely clear where this path is coming from. I’m guessing it’s somehow related to the Builder but I’m not an expert (yet) on this codebase so I might be wrong. 

Is it possible to simply use my own custom org.apache.karaf.features.cfg file in my integration test project as a workaround until this issue is solved ? 

Thanks a lot for your help,
cheers,
  Serge…
