This does not appear to be possible.
For those interested, my workaround is to create a new, empty project
and supply only that project to Maven instead of the empty list.
final MavenProject dummyProject = new MavenProject();
dummyProject.setArtifactId("nothing");
dummyProject.setVersion("(everything is up-to-date).");
This then outputs
<snip/>
[INFO] Scanning for projects...
[INFO]
[INFO] ------------------------------------------------------------------------
[INFO] Building nothing (everything is up-to-date).
[INFO] ------------------------------------------------------------------------
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
<snip/>
So not perfect but close enough. :-)
