Deployed timestamped snapshot version does not change

[jglick]

mvn deploy
# edit some file
mvn deploy

(3.8.6) on a *-SNAPSHOT project using nexus-staging-maven-plugin will deploy snapshots with two different versions (…-1 and …-2), as expected. But

mvnd deploy
# edit some file
mvnd deploy

(0.7.1) seems to redeploy the same timestamped version (…-1). Maybe whatever inside Maven holds a consistent version number across reactor modules (recently added) is improperly being cached?

Fwiw, the nexus-staging-maven-plugin uses very old maven api, I would advise to switch to the standard deploy plugin instead.
Also a way to reproduce the problem would be required to identify where the problem comes from.

OK, then unclear where fault may lie. Timestamped snapshots are always a mess anyway. CC @stephenc @jtnord

Not an option if you need to automate interactions with Nexus I am afraid—opening a staging repository, grouping changes, closing it, promoting it to release.

a way to reproduce the problem

Anyway it seems I cannot reproduce on demand.
