How to download the latest artifact using REST API in Nexus 3?
Suggest following this ticket: https://issues.sonatype.org/browse/NEXUS-14407
I believe that is what you’re asking for, not yet implemented.
May be workarounds I am unaware of.
Note that NEXUS-14407 is fixed in the upcoming 3.16.0 release, which should be out later this month.
