Project description


A python-based command-line interface and API client for Sonatype's Nexus OSS 3.

Build Status CodeFactor codecov Documentation Status


  1. Compatible with Nexus 3 OSS
  2. Python API and command-line support
  3. Artefact management: list, upload, download, delete.
  4. Repository management:
    1. Create hosted and proxy.
    2. Create bower, maven, npm, nuget, pypi, raw, rubygems, yum.
    3. Content type validation, version and write policy.
    4. Delete.
  5. Groovy script management: list, upload, delete, run.

The actions above are performed using the Nexus REST API if the endpoint is available, otherwise a groovy script is used.

Please note that some Nexus 3 features are not currently supporter. Assistance implementing missing support is very welcome. Please have a look at the issues and contribution guidelines.


The nexus3-cli package is available on PyPi. You can install using pip/pip3:

pip install nexus3-cli


Command line

For a quick start, use the sonatype/nexus3 Docker image:

docker run -d --rm -p 8081:8081 sonatype/nexus3

Nexus will take a little while to start-up the first time you run it. You can tell when it's available by looking at the Docker instance logs or browsing to http://localhost:8081.

If you haven't changed the default Nexus credentials, you can use it straight away; here's the list of default repositories:

$ nexus3 repo list
Name                                     Format  Type    URL
----                                     ------  ----    ---
maven-snapshots                          maven2  hosted  http://localhost:8081/repository/maven-snapshots
maven-central                            maven2  proxy   http://localhost:8081/repository/maven-central
nuget-group                              nuget   group   http://localhost:8081/repository/nuget-group                          nuget   proxy   http://localhost:8081/repository/
maven-releases                           maven2  hosted  http://localhost:8081/repository/maven-releases
nuget-hosted                             nuget   hosted  http://localhost:8081/repository/nuget-hosted
maven-public                             maven2  group   http://localhost:8081/repository/maven-public

The login command will store the service URL and your credentials in ~/.nexus-cli (warning: restrictive file permissions are set but the contents are saved in plain-text).

$ nexus3 login
Nexus OSS URL (http://localhost:8081):
Nexus admin username (admin):
Nexus admin password (admin123):

Create a Yum repository with read-only access:

$ nexus3 repo create hosted yum my-yum-repository --write=deny
Created repository: my-yum-repository

The CLI output can be filtered using standard *nix tools, e.g. using grep:

$ nexus3 repo list | grep my-yum-repository
Name                                     Format  Type    URL
----                                     ------  ----    ---
my-yum-repository                        yum     hosted  http://localhost:8081/repository/my-yum-repository

For all commands and options, run nexus3 -h.


See API documentation.


The automated tests are configured in .travis.yml. To run tests locally, install the package with test dependencies and run pytest:

pip install -e .[test]
pytest -m 'not integration'

Integration tests require a local Nexus instance listening on 8081 or as configured in ~/.nexus-cli; the example configuration used for tests is in tests/fixtures/dot-nexus-cli.

docker run -d --rm -p --name nexus sonatype/nexus3
./tests/  # the Nexus instance takes a while to be ready
pytest -m integration
docker kill nexus

Nota Bene: if you re-run integration tests without re-creating or cleaning-up the dev Nexus instance, test will fail because objects created during tests will already exist.
