Adoptium champions open-source Java solutions, empowering businesses with cutting-edge technology and collaborative innovation.
Founded on the principles of community-driven development, Adoptium has become a cornerstone of the Java ecosystem, driving forward-thinking solutions and fostering a culture of shared knowledge.
We achieve this through a set of Projects under the Adoptium PMC and a close working partnership with external projects, most notably OpenJDK for providing the Java SE runtime implementation.
The AdoptOpenJDK project was established in 2017 following years of discussions about the general lack of an open and reproducible build and test system for OpenJDK source across multiple platforms. Since then it has grown to become a leading provider of high-quality OpenJDK-based binaries used by enterprises in embedded systems, desktops, traditional servers, modern cloud platforms, and large mainframes. The Eclipse Adoptium project is the continuation of the original AdoptOpenJDK mission.

Eclipse Adoptium provides runtime binaries that are high performance, enterprise-grade, cross-platform, open-source licensed, Java SE TCK-tested and compliant for general use across the Java ecosystem. Eclipse Adoptium also provides artefacts including open-source infrastructure as code, a comprehensive continuous integration build and test farm, and extensive quality assurance tests. These artefacts may be used by Eclipse Adoptium projects and other runtime technology builders to ensure the provision of secure, Java SE TCK-tested and compliant, production-ready runtimes.
