cljfx 2020-09-30 | Slack Archive

to provide more info, I tried to create a custom task in leiningen as follows:

(ns leiningen.ujar
  (:require leiningen.uberjar
            leiningen.core.eval))

(defn ujar [project]
  (leiningen.uberjar/uberjar project)
  (leiningen.core.eval/eval-in-project project `(javafx.application.Platform/exit)))

the problem is that uberjar never returns, it hangs waiting for the thread to be closed. I looked at the last file compiled by uberjar and placed the exit code at the end of the namespace and it worked (finished the build)... but, does not look like a good approach. (also, I think the runtime will be compromised in this way... didn't test yet..)

vlaaad05:09:40

@iagwanderson you can try skipping javafx initialization

vlaaad05:09:44

vlaaad05:09:58

While that's not a guarantee, it helps in most cases

seancorfield06:09:38

@iagwanderson Why do you need to do AOT? You can build an uberjar without AOT and still run the resultant JAR, albeit with a slightly less compact command. Another alternative is to write a stub -main ns that uses runtime require/`resolve` (or requiring-resolve if you're on 1.10) to invoke your actual program main. Then AOT of that ns will not transitively try to compile the rest of your code but you can still run the JAR with java -jar.

bartuka12:09:01

thanks for the comments. Let me try to explain more about what I am doing. I developed a cljfx page (using list-view, label, button basically) and I am trying require the namespace of this project on another project. (similar to a REBL)

bartuka12:09:19

when I compiled without AOT, I got an error from cljfx.coerce

vlaaad12:09:39

what was the error?

bartuka12:09:43

Let me reproduce and send the error message here...

vlaaad12:09:01

this means you don’t have JavaFX on your classpath

java 8?

java 11

hmm

let me try to explicitly add the javafx dependencies in the project

vlaaad12:09:40

have you changed the jdk from java 8 to java 11?

bartuka12:09:20

I have been using java 11 for a long time now.

vlaaad12:09:27

ah, cool

bartuka12:09:52

looking at the REBL page, they explicitly add javafx dependencies on java 11 projects

bartuka12:09:56

maybe I need to do the same

vlaaad12:09:17

nope, cljfx adds dependencies on javafx by itself

bartuka12:09:48

uhmmm.. makes sense

vlaaad12:09:12

I would say some context is missing…

vlaaad12:09:22

have you built a cljfx app as uberjar?

bartuka12:09:36

yes

vlaaad12:09:14

is the OS used when the uberjar was built the same as OS where you use that uberjar?

bartuka12:09:35

yes, Linux arch 5.4.68-1-lts

vlaaad12:09:34

hmm, I don’t know what else to ask 🙂

bartuka12:09:21

hehe.. this is the link to my project https://github.com/wandersoncferreira/replr

bartuka12:09:46

pet project to explore some ideas that I was curious at (cljfx, nrepl integration)

bartuka12:09:14

hey @vlaaad, I doubled checked the version of the jdk used by the project that I am trying to import the cljfx app into

bartuka12:09:30

and it was java 8 there 😞 my bad. Now I synced both in java 11

vlaaad12:09:37

np 🙂

bartuka12:09:39

"worked", but not. hehe different error 😃

bartuka12:09:44

which means progress

bartuka12:09:46

🙂

vlaaad12:09:51

by the way, cljfx supports java 8 as well

bartuka12:09:56

Loading library prism_es2 from resource failed: java.lang.UnsatisfiedLinkError: /root/.openjfx/cache/14/libprism_es2.so: libX11.so.6: cannot open shared object file: No such file or directory
java.lang.UnsatisfiedLinkError: /root/.openjfx/cache/14/libprism_es2.so: libX11.so.6: cannot open shared object file: No such file or directory

bartuka12:09:58

my app is running inside a docker container too (if that is relevant here)

vlaaad12:09:03

but java 8 support relies on JavaFX being a part of a JDK (it was there before)

vlaaad12:09:16

I would guess docker containers are headless?

bartuka12:09:05

yes, true

bartuka12:09:48

not sure now if I was able to run rebl inside my container too

vlaaad12:09:30

why would you want to run UI app in a docker container?

bartuka12:09:02

actually I am thinking in the current setup my company uses. Every project has a docker-compose attached to it and I would like this UI to be open while they are developing.

bartuka12:09:06

anyway... thanks so much @vlaaad... it is working fine. Interesting to see the amount of fns a relative small app in my company have. haha.

People go completely overboard with docker
