I got an error every time I try to run the javaFX application generated by Intelij. I selected kotlin langage to code and i use gradle version 8.7. The error say that he can’t find the package in module

Error occurred during initialization of boot layer

java.lang.module.FindException: Error reading module: D:\Dev\InteliJ\Intelij Project\ChatApplication\ChatApplicationDesktop\build\classes\java\main

Caused by: java.lang.module.InvalidModuleDescriptorException: Package fr.plaglefleau.chatapplicationdesktop not found in module

But the package does exist and does have kotlin class in it.

package fr.plaglefleau.chatapplicationdesktop  
import javafx.application.Application 
import javafx.fxml.FXMLLoader 
import javafx.scene.Scene 
import javafx.stage.Stage  
class HelloApplication : Application() {     
    override fun start(stage: Stage) {         
        val fxmlLoader = FXMLLoader(HelloApplication::class.java.getResource("hello-view.fxml")) 
        val scene = Scene(fxmlLoader.load(), 320.0, 240.0)         
        stage.title = "Hello!"        
        stage.scene = scene         
        stage.show()     
    }   
    fun main() {     
        Application.launch(HelloApplication::class.java) 
    }
} 

package fr.plaglefleau.chatapplicationdesktop

import javafx.fxml.FXML
import javafx.scene.control.Label

class HelloController {
    @FXML
    private lateinit var welcomeText: Label

    @FXML
    private fun onHelloButtonClick() {
        welcomeText.text = "Welcome to JavaFX Application!"
    }
}

(don’t know if it’s relevant to post this code here)

I try to regenerate the project in java and still got the same error. I also try to open my module

open module fr.plaglefleau.chatapplicationdesktop {     
    requires javafx.controls;     
    requires javafx.fxml;     
    requires kotlin.stdlib;       
    exports fr.plaglefleau.chatapplicationdesktop; 
}

plugins {
    id 'java'
    id 'application'
    id 'org.jetbrains.kotlin.jvm' version '1.8.22'
    id 'org.javamodularity.moduleplugin' version '1.8.12'
    id 'org.openjfx.javafxplugin' version '0.0.13'
    id 'org.beryx.jlink' version '2.25.0'
}

group 'fr.plaglefleau'
version '1.0-SNAPSHOT'

repositories {
    mavenCentral()
}

ext {
    junitVersion = '5.10.0'
}


tasks.withType(JavaCompile) {
    options.encoding = 'UTF-8'
}

application {
    mainModule = 'fr.plaglefleau.chatapplicationdesktop'
    mainClass = 'fr.plaglefleau.chatapplicationdesktop.HelloApplication'
}
kotlin {
    jvmToolchain(17)
}

javafx {
    version = '21'
    modules = ['javafx.controls', 'javafx.fxml']
}

dependencies {

    testImplementation("org.junit.jupiter:junit-jupiter-api:${junitVersion}")
    testRuntimeOnly("org.junit.jupiter:junit-jupiter-engine:${junitVersion}")

    implementation("org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.2.4")
    implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.9.0-RC")
}

test {
    useJUnitPlatform()
}

jlink {
    imageZip = project.file("${buildDir}/distributions/app-${javafx.platform.classifier}.zip")
    options = ['--strip-debug', '--compress', '2', '--no-header-files', '--no-man-pages']
    launcher {
        name = 'app'
    }
}

jlinkZip {
    group = 'distribution'
}

I obviously also try with the generated module-info.java

module fr.plaglefleau.chatapplicationdesktop {

    requires javafx.controls;
    requires javafx.fxml;     
    requires kotlin.stdlib;       
    
    opens fr.plaglefleau.chatapplicationdesktop to javafx.fxml;     
   
    exports fr.plaglefleau.chatapplicationdesktop; 
}
