🌏 Overview

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.
