fabric8io docker-maven-plugin assembly and external artifact
OK, have figured it out.
The issue was that the pom.xml specified some external configuration
<external> <type>properties</type> <prefix>docker</prefix> <mode>override</mode></external>But as the doco here (http://dmp.fabric8.io/#property-configuration) says, this means the <build> configuration (including my assembly) in the pom.xml will be ignored. I am not sure why our standard uses the external configuration, will chase up our ops people on that. But removing this <external> section and everything works.
