Maven Central contains over 260,000 artifacts and serves over 70 million downloads every week. It has become the principal resource for exchanging Java artifacts with demand doubling year over year. Getting artifacts into Central is the most effective way to get your software to developers since every build tool that can download Java libraries knows where to look for a world of libraries and dependencies, and that single, authoritative place is Maven Central.
Earlier this year, we announced the availability of official repositories in the UK to improve performance for the users in Europe. Today we are making the artifact download statistics available to the projects whose artifacts are served by Central. This has been one of the most frequently requested features by project teams. Since the raw Central logs are larger than seven gigabytes every day, processing this data is no small undertaking.
The statistics are available to all projects hosted using Nexus at http://oss.sonatype.org, http://repository.apache.org and http://nexus.codehaus.org. These three avenues represent the majority of projects actively contributing artifacts. Nexus’ security mechanism already in place on these instances provides a mapping of repository path to project which allowed us to easily roll up the counts for each team.
