Issue with third-party library using Ikonly: Exception in thread "JavaFX Application Thread" java.lang.UnsupportedOperationException: Cannot resolve 'mdi-close'

[fusionart]

Hello,

I am having issue with "mdi" icon pack used from GemsFX.
I asked GemsFX for help and they told me that the problem is not with their components but with Ikonli.
Here you can see their answer: dlsc-software-consulting-gmbh/GemsFX#53

When I start the app from IntelliJ everything is working correctly.

But when I build a fatjar using "mvn compile package" command and maven-shade-plugin and run it using "java -jar", I get this errors on runtime:
Exception in thread "JavaFX Application Thread" java.lang.UnsupportedOperationException: Cannot resolve 'mdi-close'
or
Exception in thread "JavaFX Application Thread" java.lang.UnsupportedOperationException: Cannot resolve 'mdi-clock'

The second issue is causing problems loading the stage with the Time Picker. It is making the form almost unusable.

I am running the app on Ubuntu 22.04, JDK openjdk 18.0.2 2022-07-19 ,OpenJDK Runtime Environment Temurin-18.0.2+9 (build 18.0.2+9) and JavaFX 18, GemsFX version 1.47.0.

I've also added to the POM file of the project the latest version of Ikonli: ikonli-core, ikonli-javafx and ikonli-materialdesign-pack but this didn't solve my problem.

[aalmiray]

When creating a fatjar make sure to merge service files otherwise icon providers won't be found https://kordamp.org/ikonli/#_creating_a_fat_jar

Thanks a lot @aalmiray for the help. This solution was the missing part. Now it works perfectly.

@aalmiray can you tell me any changes I can make to my pom.xml? I'm still getting errors with Exception in thread "JavaFX Application Thread" java.lang.UnsupportedOperationException: Cannot resolve 'mdmz-plus'

This is my pom.xml
