Upload artifacts to Nexus, without Maven

I have a non-Java project that produces a versioned build artifact, and I want to upload this to a Nexus repository. Because the project isn't Java, it doesn't use Maven for builds. And I'd rather not introduce Maven/POM files just to get files into Nexus.

The links on blogs to the Nexus REST API all end up at a sign-in wall, with no "create user" link that I can see.

So, what's the best (or any reasonable) way to upload build artifacts to a Nexus repository without Maven? "bash + curl" would be great, or even a Python script.

Solution

Have you considering using the Maven command-line to upload files?

mvn deploy:deploy-file \
    -Durl=$REPO_URL \
    -DrepositoryId=$REPO_ID \
    -DgroupId=org.myorg \
    -DartifactId=myproj \
    -Dversion=1.2.3  \
    -Dpackaging=zip \
    -Dfile=myproj.zip

This will automatically generate the Maven POM for the artifact.

Update

The following Sonatype article states that the "deploy-file" maven plugin is the easiest solution, but it also provides some examples using curl:
