What Is The Central Repository?⚓︎

The Central Repository is the largest collection of Java and other open source components. It provides the easiest way to access and distribute your software components to millions of developers. It is the default repository for Apache Maven, SBT and other build systems and can be easily used from Apache Ant/Ivy, Gradle and many other tools.

A large number of open source organizations such as the Apache Software Foundation, the Eclipse Foundation, JBoss and many individual open source projects from large organizations and companies down to individual programmers publish their components to the Central Repository.

When you develop software you depend on open source components, and these external libraries are likely available on the Central Repository.

Central uses a Maven 2 repository format and hosts release components only.
