Graal config

A repository containing GraalVM native-image configurations to be used as git libraries in deps.edn.

How to use

  • Include this library as a git dependency in your native image classpath.
  • Set :deps/root to "config/<org>/<lib>"
  • In addition to this, include com.github.clj-easy/graal-build-time which automatically configures --initialize-at-build-time with clojure packages.
  • Then build your native image!

Full example for both cheshire/cheshire and com.taoensso/nippy in one build: (update versions as necessary):

{:deps
 {cheshire/cheshire                         {:mvn/version "5.10.0"}
  com.taoensso/nippy                        {:mvn/version "3.1.1"}
  com.github.clj-easy/graal-config-cheshire {:git/url   "https://github.com/clj-easy/graal-config"
                                             :git/sha   "b06e33694d2c878169958f7317ea01d9c0353ab4"
                                             :deps/root "config/cheshire/cheshire"}
  com.github.clj-easy/graal-config-nippy    {:git/url   "https://github.com/clj-easy/graal-config"
                                             :git/sha   "b06e33694d2c878169958f7317ea01d9c0353ab4"
                                             :deps/root "config/com.taoensso/nippy"}}}
