             Summary: Remove null values from AssemblyMojo configuration
                 Key: KARAF-5235
                 URL: https://issues.apache.org/jira/browse/KARAF-5235
             Project: Karaf
          Issue Type: Improvement
          Components: karaf-tooling
            Reporter: John Poth


When building Karaf distributions, it would be nice to be able to tweak the distribution using Maven profiles to add a feature or a bundle (etc..). However if the Maven profile which adds these bundles/features is not active we currently get an NPE:
