nicolas de loof commented on MNG-3691:
--------------------------------------

I understand well the snapshot usage with automatic updates when a new one is deployed. I dont undeerstand the use case of uniqueVersion=false if this is not to allow sort of "timestamp" version that ensure some reproductibility. To use such a timestamp, my POM needs to force all plugin SNAPSHOT dependencies versions.

Maybe the enforcer and release plugins should also check for this when they accept a timestamp for a plugin or dependency

> use case :
> using the release plugin as a SNAPSHOT timestamped version to ensure reproductibility.
> When an incompatible  SNAPSHOT of the release-manager is deployed, the plugin doesn't work anymore : it updated it's SNAPSHOT dependencies.
> -> uniqueVersion=false was useless to ensure reproductibility.
> The isse is that the plugin POM has a SNAPSHOT dependency. As part of the deploy process, the SNAPSHOT version SHOULD be forced to current timestamped version to follow the uniqueVersion expectation.
