Using the features-maven-plugin

(e.g. for creating your own Karaf-based distribution)
features:generate-features-file Deprecated - use features:generate-features-xml instead
features:generate-features-xml Generates a features XML descriptor for a set of bundles
features:validate Validate a features XML descriptor by checking if all the required imports can be matched to exports
