Summary:
Custom Maven extension extensions are not support fully supported
Description:
When the dependency type or the project packaging is custom, Extension Manager does not resolve properly the actual extension file (and the extension type).
Since XCOMMONS-3003 (16.4.0), the workaround is to install the JAR which contains a plexus components.xml definition of the extensions in the root namespace and to restart (it will be loaded as it of was one of the standard Maven extensions).
