Adding a Java class to Kotlin module breaks Quarkus start

[ZorinAnton]

Describe the bug

I need to start Quarkus from main function:

@QuarkusMain
class App : QuarkusApplication{

    override fun run(vararg args: String?): Int {
        println("quarkus running")
        Quarkus.waitForExit()
        return 0
    }
}

fun main() {
    val app:Class<App>? = App::class.java
    Quarkus.run(app)
    Quarkus.asyncExit()
}

This works fine, but if I add a java class (even empty) I get The supplied 'main-class' value of 'App' does not correspond to either a fully qualified class name or a matching 'name' field of one of the '@QuarkusMain' annotations It appears to me that Kotlin annotations don't get processed in this case.

Expected behavior

Start without errors

Actual behavior

Failed to start quarkus: java.lang.RuntimeException: io.quarkus.builder.BuildException: Build failure: Build failed due to errors
    [error]: Build step io.quarkus.deployment.steps.MainClassBuildStep#mainClassBuildStep threw an exception: java.lang.IllegalArgumentException: The supplied 'main-class' value of 'App' does not correspond to either a fully qualified class name or a matching 'name' field of one of the '@QuarkusMain' annotations

How to Reproduce?

quarkus-kotlin.zip

Output of uname -a or ver

Microsoft Windows [Version 10.0.22631.3155]

Output of java -version

java version "17.0.2" 2022-01-18 LTS Java(TM) SE Runtime Environment (build 17.0.2+8-LTS-86) Java HotSpot(TM) 64-Bit Server VM (build 17.0.2+8-LTS-86, mixed mode, sharing)

Quarkus version or git rev

3.8.1

Build tool (ie. output of mvnw --version or gradlew --version)

Gradle 8.6

Additional information

If I perform the same task using Java it works, but kotlin annotations are still don't seem to get recognized. Kotlin entities are not visible and I get jakarta.enterprise.inject.UnsatisfiedResolutionException: Unsatisfied dependency for type MetaRepoService and qualifiers [@Default] until I define an entity with Java.

It seems that the addition of the java source set results in Quarkus not including the Kotlin classes it it's index (when launching from the IDE). @aloubyansky any ideas of how to address it?
