The Java Ecosystem Working Group is an initiative of the Java Community Process (JCP) Executive Committee.
Its purpose is to highlight and support the open-source projects, tools, and communities that make Java so impactful.
We aim to:
- Showcase contributions from key projects across the ecosystem (build tools, frameworks, libraries, IDEs, CI/CD).
- Provide a space for collaboration, shared resources, and cross-project discussions.
- Identify and address challenges around adopting new Java versions and modern release practices.
- Support not only developers, but also educators, students, and end-users who rely on a thriving Java ecosystem.
Whether you maintain a project, contribute to tools, or simply want to help improve adoption of modern Java,
we welcome your ideas, feedback, and participation.
