That's not how Nexus is being used in Commons - but I don't know what
has been set up here, so perhaps the following is not applicable:

Nexus (as used by Commons/HttpClient) intercepts uploads to the Maven
distribution repo on people.
Instead of Maven artifacts being automatically synched with Maven
Central, Nexus stores them in a staging repo.
This must be checked and closed to new updates; it's then available to
the general public to as part of the VOTE.
If the vote succeeds, the staging repo can be released, otherwise it
is dropped. Once released, the artifacts make their way to Maven
Central as before.

Nexus does *not* change the process for non-Maven artifacts (which are
the main Tomcat release mechanism).
However once enabled for a project, the protection on the maven
distribution repo is changed so only Nexus can update it.

The benefit is that it is impossible to accidentally release Maven
artifacts using "mvn deploy" or whatever; and there is staging area
which can be used for votes.
It also checks sigs and generates hashes if necessary. It guarantees
that the voted on artifacts are the ones that are released.
The disadvantage is that one has to login to Nexus twice: to close the
staging area, and then to release or drop it at the end of the vote.

But this does not change how non-Maven artifacts are released.
