JDK Builder

JDK Builder is a domain‑specific tool for platform engineers, DevOps, and Java developers who need a tailored Java Runtime. It solves the problem of bulky JDK distributions by letting users select a base version, vendor, and a precise set of modules to include. The result is a compact, deterministic image that matches runtime needs without unnecessary components. Assumptions include availability of official module catalogs and network access during build; offline mode is supported with cached catalogs.
Conceptually, the tool models the build as inputs (version, vendor, modules, target platform) and outputs (image archive, build manifest, checksums). It uses standard JDK tooling (such as jlink) to assemble a runtime image, validates module compatibility, and provides size and boot‑activity estimates. Users can reproduce the same image across environments by recording the exact inputs and environment details.
Audience and value: platform teams, cloud natives, and CI/CD pipelines benefit from reproducible builds, offline caches, and predictable startup behavior. Unique differentiators include guided module selection, strict validation, and metadata capture that supports auditing and compliance. The tool focuses on safety, traceability, and minimal runtime surface area for containerized deployments.
Core features and use cases: input validation, version mapping, module filtering, target packaging, and integrity checks. Typical use cases include creating a minimal JDK for a microservice, packaging a JDK for an edge device, or generating a predictable runtime for a multi‑arch container. Outputs include a packaged image, a manifest, and checksums to enable verification in deployment pipelines.
