Hi all! I’m seeing some errors trying to make a native image for a project with a (transitive) dependency on https://github.com/vsch/flexmark-java. Would appreciate any pointers on resolving this issue. Detailed error messages and more context in 🧵

I’m including com.github.clj-easy/graal-build-time {:mvn/version "0.1.4"} in my deps.edn and am using io.github.clojure/tools.build {:mvn/version "0.9.4"}. build.clj is pretty simple: 

(ns build
  (:require [clojure.tools.build.api :as b]))

(def class-dir "classes")

(def basis (b/create-basis {:project "deps.edn"}))

(def jar-file "luciano-service.jar")

(defn clean [_]
  (b/delete {:path "target"}))

#_{:clj-kondo/ignore [:clojure-lsp/unused-public-var]}
(defn uberjar [_]
  (clean nil)
  (b/copy-dir {:src-dirs ["src" "resources"]
               :target-dir class-dir})
  (b/compile-clj {:basis basis
                  :src-dirs ["src" "resources"]
                  :class-dir class-dir})
  (b/uber {:class-dir class-dir
           :uber-file jar-file
           :basis basis
           :main 'li.laratel.core}))

You need to initialize the Java classes that are used from Clojure also at build time.

borkdude22:05:02

I'll check back tomorrow but hopefully this will help you a bit.

Luciano Laratelli22:05:34

Thank you! I’ll see if I can make progress on that 🙂

borkdude22:05:47

Also see these docs: https://github.com/clj-easy/graal-docs and you can check babashka, clj-kondo, jet and other projects as examples
