Generate hk2 inhabitant files with Gradle for Kotlin files

[pmwmedia]

The HK2 Metadata Generator seems to generate nothing for Kotlin projects. Is there any way to adapt the HK2 Metadata Generator for Kotlin?

Currently I'm using a dirty workaround with a custom Gradle task:

dependencies {
    "implementation"(kotlin("stdlib-jdk8"))
    "implementation"("org.glassfish.hk2:hk2:2.6.1")
    "implementation"("org.glassfish.jersey.containers:jersey-container-jetty-http:2.30")
    "compileOnly"("org.glassfish.hk2:hk2-inhabitant-generator:2.6.1")

    invoke {
        configurations["implementation"].isCanBeResolved = true
    }
}

tasks {
    val hk2InhabitantGeneration = register<JavaExec>("hk2InhabitantGeneration") {
        onlyIf { project.buildDir.resolve("classes/kotlin/main").isDirectory }

        classpath = configurations["compileClasspath"]
        main = "org.jvnet.hk2.generator.HabitatGenerator"
        args = listOf(
                "--searchPath",
                configurations["implementation"].asPath,
                "--file",
                project.buildDir.resolve("classes/kotlin/main").absolutePath,
                "--directory",
                project.buildDir.resolve("resources/main/META-INF/hk2-locator").absolutePath)
    }

    named("classes") {
        doFirst {
            hk2InhabitantGeneration.get().exec()
        }
    }
}
