I think this is the code where I stumbled onto this. Looks like I since added a
ModelResolver to avoid the issue, but try setting that to null instead and see
what happens.

I'll have to see if I can repro this. This as not a command line invocation of
Maven. It happened because some of my own code attempted to pass null for an
argument.

I don't understand the {{[unknown-version]}}-part. As if the parent-pom is
invalid. Do you have a minimal pom to reproduce this issue?
