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)))bartuka 2020-09-30T03:29:05.019300Z
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..)

@iagwanderson you can try skipping javafx initialization

vlaaad 2020-09-30T05:18:58.019800Z
While that's not a guarantee, it helps in most cases
seancorfield 2020-09-30T06:03:38.022400Z
@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.

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)
bartuka 2020-09-30T12:04:19.024500Z
when I compiled without AOT, I got an error from cljfx.coerce
vlaaad 2020-09-30T12:04:39.025100Z
what was the error?
bartuka 2020-09-30T12:04:43.025300Z
Let me reproduce and send the error message here...

this means you don’t have JavaFX on your classpath
vlaaad 2020-09-30T12:09:13.027500Z
java 8?
bartuka 2020-09-30T12:09:19.027700Z
java 11
vlaaad 2020-09-30T12:10:02.028200Z
hmm
bartuka 2020-09-30T12:10:12.028500Z
let me try to explicitly add the javafx dependencies in the project
vlaaad 2020-09-30T12:10:40.029200Z
have you changed the jdk from java 8 to java 11?
bartuka 2020-09-30T12:11:20.029900Z
I have been using java 11 for a long time now.
vlaaad 2020-09-30T12:11:27.030100Z
ah, cool
bartuka 2020-09-30T12:11:52.030700Z
looking at the REBL page, they explicitly add javafx dependencies on java 11 projects
bartuka 2020-09-30T12:11:56.031Z
maybe I need to do the same
vlaaad 2020-09-30T12:12:17.031500Z
nope, cljfx adds dependencies on javafx by itself
bartuka 2020-09-30T12:12:48.032100Z
uhmmm.. makes sense
vlaaad 2020-09-30T12:13:12.032500Z
I would say some context is missing…
vlaaad 2020-09-30T12:13:22.032800Z
have you built a cljfx app as uberjar?
bartuka 2020-09-30T12:13:36.033Z
yes
vlaaad 2020-09-30T12:14:14.033600Z
is the OS used when the uberjar was built the same as OS where you use that uberjar?
bartuka 2020-09-30T12:14:35.033900Z
yes, Linux arch 5.4.68-1-lts
vlaaad 2020-09-30T12:15:34.034200Z
hmm, I don’t know what else to ask 🙂
bartuka 2020-09-30T12:17:21.034500Z
hehe.. this is the link to my project https://github.com/wandersoncferreira/replr
bartuka 2020-09-30T12:17:46.035200Z
pet project to explore some ideas that I was curious at (cljfx, nrepl integration)
bartuka 2020-09-30T12:27:14.036800Z
hey @vlaaad, I doubled checked the version of the jdk used by the project that I am trying to import the cljfx app into
bartuka 2020-09-30T12:27:30.037200Z
and it was java 8 there 😞 my bad. Now I synced both in java 11
vlaaad 2020-09-30T12:27:37.037500Z
np 🙂
bartuka 2020-09-30T12:27:39.037700Z
"worked", but not. hehe different error 😃
bartuka 2020-09-30T12:27:44.038Z
which means progress
bartuka 2020-09-30T12:27:46.038200Z
🙂
vlaaad 2020-09-30T12:27:51.038400Z
by the way, cljfx supports java 8 as well

my app is running inside a docker container too (if that is relevant here)
vlaaad 2020-09-30T12:29:03.040100Z
but java 8 support relies on JavaFX being a part of a JDK (it was there before)
vlaaad 2020-09-30T12:29:16.040400Z
I would guess docker containers are headless?
bartuka 2020-09-30T12:30:05.040700Z
yes, true
bartuka 2020-09-30T12:30:48.041100Z
not sure now if I was able to run rebl inside my container too
vlaaad 2020-09-30T12:31:30.041400Z
why would you want to run UI app in a docker container?
bartuka 2020-09-30T12:33:02.042700Z
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.
bartuka 2020-09-30T12:37:06.043700Z
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.
zilti 2020-09-30T20:18:35.044900Z
People go completely overboard with docker
