The Aries Blueprint Maven plugin [1] should be properly configured to specify the scanpath used to find the annotations. The current configuration, inherited from odlparent uses org.opendaylight as scanpath, this force the plugin to traverse all the modules on which Netvirt is depending on, e.g. SFC, and generates wrong entries in the autowire.xml files refering the beans, singleton and services annotated in those modules. Those autowire.xml prevent the SingleFeatureTest from succeeding because the blueprint container looks for components that are not available. For this reason [2] and [3] have put this in evidence.
