Nexus 3 Exporter

A little script for downloading all assets inside a Nexus 3 repository, following the repository's asset format. For example, fed with a Nexus 3 Maven repositories, this script yields a standard Maven repository structure containing all artifacts.

Usage

You need Python 3 to run this script. You also need to install the requirements listed in requirements.txt (e.g., using pip).

Launch the script with:

python3 nexus3_exporter.py [-h] [-o output_dir] [-u username] [-n] <server> <repo>

You have to supply two arguments:

• server is the root URL to the Nexus 3 server which contains the repository. For example, this might be https://repo.loadingbyte.com.
• repo is the name of the repository whose assets shall be downloaded. For example, this might be maven-releases.

Optionally, you can supply:

• -h shows a help page.
• -o output_dir specifies the directory where to store the downladed assets. If none is provided, the repository name will be used as the name of the output directory.
• -u username specifies an HTTP Basic Auth username. You will be prompted for the password.
• -n disables the SHA-1 hash verification of downloaded assets.

Example call:

python3 nexus3_exporter.py https://repo.loadingbyte.com maven-releases

Importing

This script only exports assets from Nexus 3 repositories, but not vice versa. For importing assets, we recommend using the official import scripts.
