This feature thread tracks the evolution of the GitHub Copilot SDK for Java, enabling Java developers to integrate AI capabilities into their enterprise applications in a framework-agnostic and AI-vendor-neutral manner. This post introduces the SDK, detailing its core features such as creating Copilot agent sessions, registering tools via annotations or lambdas, sending prompts, and receiving structured responses. It highlights the use of virtual threads for efficient agent processing and real-time UI updates via WebSockets. The SDK supports direct integration with various AI model providers and offers fine-grained control over system messages. A sample Jakarta EE 11 application demonstrates the SDK's capabilities, including defining tools with `@CopilotTool` and inline lambdas, cross-class tool scanning, and the `sendAndWait` method for the agentic loop.
