It's basically crashing while loading libraries
The relevant part of the stack is
platform.clj: 6 cljfx.jdk.platform/initialize
platform.clj: 4 cljfx.jdk.platform/initialize
platform.clj: 30 cljfx.platform/initialize
platform.clj: 29 cljfx.platform/initialize
api.clj: 75 cljfx.api/eval24166
api.clj: 70 cljfx.api/eval24166
Which looks like here: https://github.com/cljfx/cljfx/blob/master/src/cljfx/api.clj#L70
(defonce
^{:doc "Starts JavaFX runtime and sets implicit exit to false if JavaFX wasn't started
Either `:cljfx.platform/initialized` or `:cljfx.platform/already-initialized`"}
initialized
(platform/initialize))I'm not quire sure what the issue is here (I still don't have a good mental picture for Clojure's compilation model)
I then double checked the differences between our projects.. and if I disable AOT compilation, remove (:gen-class :main true) and switch to depstar then it seems I can generate a jar without crashing (though the jar doesn't run GUI but just drops me into a REPL when I run java -jar myapp.jar)
Maybe I'm doing something wrong - but I feel there is some larger issue

It seems (according to a conversation I had on IRC) that the issue is that you have a side-effect in a def. So this will get evaluated during compilation. Maybe this initialization can happen when the renderer is first launched so that it only happens at runtime?

Hi!
I guess I'll eventually need to create a FAQ since this issue seems to be brought up from time to time, and the problem is — you can't AOT-compile cljfx without starting JavaFX runtime. I described why it is like that here. There, the reported problem is that lein uberjar never finishes because cljfx starts javafx application thread that needs to be explicitly terminated. It prevents normal compilation to hang, and it will fail if we compile it on a machine without display.
One workaround that might require changing cljfx was suggested to not start javafx application thread when *compile-files* is true (which indicates that compilation is in progress). It still is not a reliable way to AOT-compile cljfx since compilation will fail if you have any class from javafx.scene.control package imported in your code. It will help in some cases though, so I might implement it.
I think I'll use a system property like cljfx.initialize-javafx so it will not be a breaking change for existing workflows that compile cljfx apps on a machine with a display.
Another possibility that you might want to explore is to compile cljfx with javafx in headless mode, and then use compiled classes with normal javafx dependencies to build an uberjar. It won't be as easy as lein uberjar, but if you want to give it a try, I can start with how I setup headless javafx for tests in github actions.

I don't really understand how to integrate the headless javafx into my compilation, sorry. Could you indicate where you are doing that in your hn project? Because you setup CI there and it seems to work smoothly without any funny stuff.
If it's too involved then I guess I will just skip CI entirely. It'd simplify my workflow but it's not essential. Not something to complicate my life over :)

I don't do AOT compilation in hn project :)

kxygk
commented on June 5, 2024
Ah! Right! ...
And I can't get things working without AOT b/c no matter what I try it doesn't seem to be able to find my -main (either Error: Could not find or load main class sausage.core or I get dropped into a REPL). Clojure build tools are a pain in the ass haha :)
I guess I'll stick to just uploading binaries manually for uberjar builds for now and plug away at this (b/c it's the only practical way for me to ultimately make Windows/MacOS binaries). Thanks for the help as always!

commented on June 5, 2024
You can use clojure.main as a main class that is then calls your main, that's what hn does — effectively calls clojure.main -m hn.core.

commented on June 5, 2024
Ohhhhh, you specify that in the jpackage step. So the intermediary uberjar isn't supposed to launch. I should have actually clones the repo and tried it locally :)
from cljfx.
kxygk
commented on June 5, 2024
okay, I got it working.
I get what you meant now. I can run the non-AOT compiled jar with java -sausage.jar -m sausage.core - though I'm not sure how I'd begin to bundle that resulting uberjar into something double clickable by a user (though in fairness the AOT uberjars also don't launch on double click)
There were a few gotchas that I'll just mention in case someone else stumbles on this
cambadacan't make an uberjar with no AOT compiled maindepstarsspits thousands of warnings about duplicate classes b/c of the crossplatform fix you gave me on reddit- so to make the warnings go away I have to make it non-cross-platform again
- because I need to remove the
(:gen-class :main true)from mycore.cljfile, I can't just have another alias to continue to build AOT locally (other than by uncommenting and then recommenting it before I commit each time) - the non-AOT app take an eyewatering 17 seconds to launch vs. 8 seconds with AOT .. which was still bad, but it's not to the point where you're wondering if it crashed or not haha :)
Now that I have a super slow non crossplatform version I guess I need to look into getting jpackage working now :)
Sorry about the link-spam. I kept force-pushing the same commit as i tweaked it
from cljfx.

By the way, I don't receive notifications for pushed commits that reference this issue :)
I released 1.7.0 that makes it easier to AOT-compile apps that use cljfx, please give it a try — see relevant readme section.

This is fantastic! It works great! I spent all day fighting Github Actions and now I have Releases :)
Well I'm still trying to figure out how to get a prerelease to track master .. but at least I know that the uberjar is getting built and it works :) This will make my life much easier. Thank you so much again!
