Michael Osipov commented on MNG-8058:
-------------------------------------
This is not a problem of {{.mvn/maven.config}}, but are deliberate restriction
in {{<version />}}. It can contain only CI-friendly expressions.
[~sjaranowski], [~gnodet].
Personal opinion: We should not open that gate to resolution hell.
