quarkus Gradle: `:quarkusDependenciesBuild` uses this output of `:jandex` without declaring dependency

Describe the bug

A new minimal Quarkus project using Gradle 8.10. as build system fails to build due to a missing dependency declaration to the org.kordamp.gradle.jandex plugin.

Expected behavior

Build should be successful.

When removing the Jandex plugin from build.gradle.kts, the build succeeds:

❯ ./gradlew build

BUILD SUCCESSFUL in 1s
7 actionable tasks: 6 executed, 1 up-to-date

Actual behavior

❯ ./gradlew build
> Task :quarkusDependenciesBuild FAILED

FAILURE: Build failed with an exception.

* What went wrong:
A problem was found with the configuration of task ':quarkusDependenciesBuild' (type 'QuarkusBuildDependencies').
  - Gradle detected a problem with the following location: '/path/to/quarkus-jandex/build/resources/main'.
    
    Reason: Task ':quarkusDependenciesBuild' uses this output of task ':jandex' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.
    
    Possible solutions:
      1. Declare task ':jandex' as an input of ':quarkusDependenciesBuild'.
      2. Declare an explicit dependency on ':jandex' from ':quarkusDependenciesBuild' using Task#dependsOn.
      3. Declare an explicit dependency on ':jandex' from ':quarkusDependenciesBuild' using Task#mustRunAfter.
    
    For more information, please refer to https://docs.gradle.org/8.10.2/userguide/validation_problems.html#implicit_dependency in the Gradle documentation.

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

}

repositories {
	mavenCentral()
}

dependencies {
	implementation(enforcedPlatform("io.quarkus.platform:quarkus-bom:3.15.1"))
}

group = "com.example"
version = "1.0.0-SNAPSHOT"

settings.gradle.kts:

pluginManagement {
	repositories {
		mavenCentral()

Other affected tasks:

io.quarkus.gradle.tasks.QuarkusBuildDependencies
io.quarkus.gradle.tasks.QuarkusShowEffectiveConfig
io.quarkus.gradle.tasks.ImageBuild

Apparently anything inheriting from io.quarkus.gradle.tasks.QuarkusBuildTask.

Same issue. And try to use the afterEvaluate to resolve it.

afterEvaluate {
    var taskJandex = tasks.named("jandex")
    var quarkusDependenciesBuild = tasks.named("quarkusDependenciesBuild")
    println "Task jandex: $taskJandex"
    println "Task quarkusDependenciesBuild: $quarkusDependenciesBuild"
    if (taskJandex && quarkusDependenciesBuild) {
        quarkusDependenciesBuild.get().dependsOn(taskJandex)
    } else {
        println("One or both jandex related tasks are not present. Task quarkusDependenciesBuild.dependsOn(jandex).")
        println("Task jandex: $taskJandex")
        println("Task quarkusDependenciesBuild: $quarkusDependenciesBuild")
    }
}
