Gradle's Kotlin DSL script cannot start Quarkus application

Question

I'm in my journey to (try to) migrate the Gradle script(s) –written in Groovy- that I have in a (working) Quarkus 1.1.0.Final proof-of-concept project into Kotlin DSL, but somehow, after migrating the script(s), the application doesn't start anymore. Again, the project works fine with the Groovy Gradle script(s), so I don't know what I could be missing.

This is what I have so far in gradle.properties, settings.gradle.kts, and build.gradle.kts:

#
# Dependency Versions
kotlin.version = 1.3.61
quarkus.version = 1.1.0.Final

#
# Gradle Settings
org.gradle.configureondemand = false
org.gradle.daemon = false

#
# System Settings
systemProp.file.encoding = UTF-8
systemProp.sun.jnu.encoding = UTF-8

pluginManagement {
  repositories {
    // mavenLocal() // Uncomment when needed
    gradlePluginPortal()
    mavenCentral()

    maven(url = uri("https://dl.bintray.com/gradle/gradle-plugins/"))
  }

  plugins {
    id("com.commercehub.gradle.plugin.avro").version("0.17.0")
    id("eclipse")
    id("idea")
    id("io.gitlab.arturbosch.detekt").version("1.3.0")
    id("io.quarkus").version("1.1.0.Final") // TODO: Read from gradle.properties
    id("org.jetbrains.kotlin.jvm").version("1.3.61") // TODO: Read from gradle.properties
    id("org.jetbrains.kotlin.plugin.allopen").version("1.3.61") // TODO: Read from gradle.properties
  }
}

Looks like you have a very similar issue to one of the issues fixed by George here: https://github.com/quarkusio/quarkus/pull/6317 . Especially this commit: https://github.com/quarkusio/quarkus/pull/6317/commits/7b07d866e5b81b46c09d59a08556b9a796c11007 .

Not entirely sure it's the same bug though. And not totally sure, the fix will be right in your case. Especially if you have a mix of Java and Kotlin classes.

Could you create a simple reproducer and open an issue on GitHub? We will then be able to check if it's already solved or needs some more love.
