MAVEN CENTRAL REPOSITORY

Maven Central + Sonatype:
The Foundation of the Java Ecosystem

We don’t just scan for risk. We help prevent it at the source. Sonatype has stewarded the Maven Central Repository for nearly two decades, securing and managing a critical piece of open source infrastructure — the world’s largest and most trusted open source Java ecosystem.

Central Repository

Pillar of Sonatype Expertise

Our stewardship of Maven Central isn’t just operational. From its early roots as a community effort to today’s professionally managed platform, Sonatype has helped scale and secure the Central Repository while preserving its free and open access for Java developers worldwide. 

Firsthand Knowledge of Open Source Hygiene

We’ve seen what good and bad publishing looks like. Our suite of products are informed by decades of upstream validation, not just downstream scanning. 

Deep Insight Into Ecosystem Behavior

We identify risky trends and emerging attack patterns by monitoring Central. That intelligence directly enriches our vulnerability data and threat modeling.

Real-Time Threat Mitigation, Not Just Detection

When zero-day events like Log4Shell hit, we don’t scramble to react. We’re already validating fixed versions and guiding response workflows.

A Working Model for Secure Supply Chain Governance

We’ve applied the principles of secure-by-design software distribution at global scale — and our customers benefit with built-in trust for the world’s open source.

Secure by Design, Powered by Sonatype

The Central Repository isn’t just another package registry. It was built on principles that prioritize structure, trust, and long-term resilience. These aren’t optional best practices — they’re hard requirements. And they’ve helped keep Maven Central remarkably free of the supply chain attacks seen in other ecosystems.

Namespace Control

Publishers must control a domain matching their groupId. No typosquatting allowed.

Mandatory Signing

All artifacts must be cryptographically signed. No unsigned or unverifiable binaries.

Metadata Validation

Components must meet formatting, structure, and policy standards before publication.

Threat Response

Malicious or suspicious uploads are detected and rejected before going live.

Frequently Asked Questions

What is Maven Central?

Maven Central, or the Central Repository is the largest public repository of open source Java components and libraries, allowing developers to share and consume Java artifacts in a standardized, reliable, and secure way. Central delivers a collection of community-supported Java components, backed by professional infrastructure that ensures speed, availability, and trust.

How do you download from the Maven Central Repository?

By default, Apache Maven, Gradle, SBT, and other tools are configured to pull dependencies from Maven Central. You can also browse and download artifacts manually from central.sonatype.com.

Who maintains Maven Central and why is that important?

Maven Central Repository is professionally managed by Sonatype. We are committed to maintaining a free, open, and reliable resource for the Java community. Our stewardship means the repository benefits from continuous performance improvements, scalable infrastructure, and proactive security practices that protect the software supply chain at its origin.

Why should I use Maven Central to build software?

With the Maven Central Repository, developers benefit from seamless software dependency resolution, empowering teams to focus on building rather than managing dependencies. By combining Maven Central with Sonatype’s broader platform — including Nexus Repository, Repository Firewall, and Lifecycle — developers gain built-in protection that helps identify and prevent risks from entering the software supply chain at the point of component request.
