Hmmm, I am missing out something over here. I have a small program that I'm trying to pack into an uberjar and AOT compile with GraalVM native image.

        :exec-fn hf.depstar/jar

I had been using build-clj to build an uberjar but I kept hitting the same problem in the graalvm generated executables:

Caused by: java.io.FileNotFoundException: Could not locate clojure/core__init.class, clojure/core.clj or clojure/core.cljc on classpath.

So I switched back to running depstar -X:uberjar with :compile-ns ':all' which compiles my namespaces. I generate my native image with the following command line invocation

native-image -cp app.jar -jar app.jar -H:Name=app -H:Path=native -H:+ReportExceptionStackTraces -J-Dclojure.spec.skip.macros=true -J-Dclojure.compiler.direct-linking=true -J-Xmx10G -J-Dtech.v3.datatype.graal-native=true --no-fallback --native-image-info

and then.... nothing, just the same error.

[billy@glorfindel qaf]$ native/app
Exception in thread "main" java.lang.ExceptionInInitializerError
	at clojure.main.<clinit>(main.java:20)
Caused by: java.io.FileNotFoundException: Could not locate clojure/core__init.class, clojure/core.clj or clojure/core.cljc on classpath.

	at clojure.lang.RT.load(RT.java:424)

Clearly I'm forgetting something pretty basal -- I'd appreciate any help on tracking down what I've forgotten to do.

java -jar app.jar

works fine, I get the clojure prompt no problem.

Read https://github.com/clj-easy/graal-docs#class-initialization

I have added graal-build-time to the project dependencies and it is bundled into the uberjar. But I see now that I have version 0.0.3(??) instead of 0.1.4; I'll try to up that first.

brightraven10:06:19

Oh yeah, that makes a difference. I see the actual prompt 😄 Thanks
