Read section 7b of the page you link, it addresses your desires
directly. I quote:

You don't have to go through steps 7.a.1. through 7.a.3. if your
artifacts have already been released or if you've generated your
artifacts using something other than Maven.  The steps below allow you
to skip using the maven-release-plugin entirely.  You can either use
the maven-gpg-plugin to sign and deploy your artifacts or upload a
staging bundle.

I obviously have been reading the wrong instructions. This is the instructions I've followed:

(dont rember which ) failed if I did not have a SNAPSHOT version and told me the problem was
that I did not have a SNAPSHOT version. So is the above page completely wrong ? Are there
other "mvn release:*" goals to run ?

is a totally obvious thing. I simply do not accept that. When I update my repository and what
I update it with is my and only my decision! I went around this problem by making a copy repository
before going through the release steps, and then deleted the copy afterwards, keeping my original
intact. It was already in the state I wanted it before releasing to maven central. The only
thing I want to release to maven central is binaries! My repository should not be touched.
So if there is no way around that happening I guess I have released my first and last code
to maven central.

you that you simply misunderstood these terms as "essential" requirements -- in fact most
of them are only "best practices". You do neither need to have the Sonatype POM, it will just
make things easier, nor do you have to use SNAPSHOTs. You can simply upload a prebuilt JAR
file. The only "hard" requirements are a "good" POM, signing the JAR with GPG, uploading it
to the OSS nexus instance, then closing and releasing it. This it at-most simple and done
in minutes. If you need help, feel free to contact me at, I can guide

>> The idea of the maven repository that has grown larger than maven itself is a completely
brilliant idea. It takes open source to a new level where anyone can just depend on other
open source code and automatically download it on build. This is really good for the open
source world (well, at least the Java/JVM part of it) . The fact that the release process
to this central repository is far too complex, I see as a really great problem, inhibiting
the easy sharing of open source work. I have often found open source tools and frameworks
that are not available in maven central, and that is because not everyone is willing to put
up with this, which now also includes myself. As I see it, either this procedure needs to
be changed to provide a trivial release of binary artifacts without affecting your poms, or
there need to be an alternative open repository providing ease of release, where it is trivial
for anyone to share their binaries for easy access by others. I'm wondering if I'm alone in
this view or if there are others who agree with me ?
