Just a note if you plan a release next week. I believe there is something broken with the maven-metadata-local.xml creation of the karaf-maven-plugin in the 4.0.4-SNAPHOST. The files are empty on my system. Using "mvn clean install -X" I see a lot of messages (sure, it depends on the stuff that is packed to your "system" directory in the custom distribution).
[DEBUG] File 'maven-metadata-local.xml' is not a features file. org.xml.sax.SAXParseException; systemId: file:/<shorten>/maven-metadata-local.xml; lineNumber: 1; columnNumber: 1; Premature end of file. The size of the maven-metadata-local.xml file is 0 bytes. I will try to further inspect this.
