Adds a Nix flake with: - Source build using two-phase FOD for Maven/Tycho dependency caching - Dev shell with Maven, JDK 11, native libs, and auto-generated toolchains.xml - OCI container image via dockerTools.buildLayeredImage - xvfb-based smoke test - nixfmt formatter - Documentation in nix/README.md Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Add modelio-src flake input pinned to commit 53eb603 - Use pinned source for mvnDeps FOD instead of local working tree - Local edits no longer invalidate the maven dependency cache - Update pin with: nix flake update modelio-src Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Refactoring: - Extract shared values (version, toolchains.xml, build.properties fixup, runtime libs) into nix/lib.nix — eliminates 3x toolchains duplication - Split FOD into nix/maven-deps.nix — package.nix is now main build only - Wire mvnDeps as separate callPackage in flake.nix Reproducibility improvements: - Delete maven-metadata-*.xml in FOD (contains <lastUpdated> timestamps) - Set -Dproject.build.outputTimestamp=1980-01-01T00:00:02Z for deterministic JARs, following nixpkgs convention (scenebuilder, nzbhydra2, etc.) - Update FOD hash to reflect new cleanup New features: - Add nix/container-run.nix — one-shot script to load and run the Docker container with X11 forwarding, config persistence, and workspace mount - Expose as `nix run .#container-run` Housekeeping: - Add /result to .gitignore (Nix build output symlink) - Add usage comments to top of flake.nix - Fix nixfmt deprecation warning (nixfmt → nixfmt-classic) - Update nix/README.md with new file layout, reproducibility strategy section, and container-run documentation Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
