Clojure core and GraalVM

It attempts to build a simple main and build a native image under several Clojure versions and GraalVM versions:

(ns simple.main
  (:gen-class))

(defn -main [& args]
  (println "Hello GraalVM!"))

Usage

Build the standalone executable jar with

lein with-profile clojure-1.10.0 do clean, uberjar

Run with

lein with-profile clojure-1.10.0 run

or using the jar

java -jar ./target/simple-clojure-1.10.0-uberjar.jar

Build all the Clojure versions and native images with

# list your GraalVM versions home directory
cat > graal.paths <<EOF
/full/path/to/my/graalvm/ver1/home
/full/path/to/my/graalvm/ver2/home
/full/path/to/my/graalvm/ver3/home
EOF
# Build and test all Clojure / GraalVM combinations
./bin/build-all.sh

The artifacts will be store in ./out folder, including the uberjars.

Currently testing the following Clojure versions

  • Clojure 1.7.0
  • Clojure 1.8.0
  • Clojure 1.9.0
  • Clojure 1.10.0
  • Clojure 1.10.1

And the following GraalVM versions have been tested.

  • GraalVM-CE-1.0.0-rc14
  • GraalVM-CE-1.0.0-rc15
  • GraalVM-CE-1.0.0-rc16
  • GraalVM-CE-19.0.0
  • GraalVM-CE-19.3.0.2
  • GraalVM-CE-19.3.1
  • GraalVM-CE-20.0.0

This is the current result:
