/**
* This class is intended to get around some problems using the normal ExplicitDefaultArtifactResolver for client building.
* We really want it to refer to the server's client_artifact_aliases.properties file, but that isn't available when run
* from the car-maven-plugin. Also the ServerInfo is missing and the ArtifactManager is not in a parent configuration
* (the car-maven-plugin starts a configuration that isn't a parent of anything. We might be able to fix that by a
* use of artifact_aliases.properties itself, but that might be for later).
