Nexus manages software artifacts required for development, deployment,
and provisioning. If you develop software, Nexus can help you share
those artifacts with other developers and end-users.

Nexus requires a "nexus" user and group; create these before running
the SlackBuild script. Examples:

# groupadd -g 252 nexus
# useradd -u 252 -s /bin/sh -d /dev/null -g nexus nexus

Should I Use 3.0 Or 2.x?

We are advising that you use Nexus Repository 3.0 if you are planning
to use npm, Bower, NuGet or Docker.

If you are using Maven, we suggest that you continue to use Nexus
Repository 2.x as we are still building features for 3.0 that many Maven
folks will find handy.
