java.lang.UnsatisfiedLinkError when using Qute TypeSafe Templates with Kotlin

When trying to use Quarkus Qute Typesafe Templates with Kotlin (converting the static class into an object as per the code below), I run into an UnsatisfiedLinkError at runtime.

The code at issue:

@Path("/subscriber")
@Produces(MediaType.TEXT_HTML)
@Consumes(MediaType.TEXT_HTML)
class SubscriberResource {

    @CheckedTemplate
    object Templates {
        external fun new(): TemplateInstance
    }

    @GET
    fun get(): TemplateInstance {
        return Templates.new()
    }
}

with the template being available in resources/templates/SubscriberResource/new.html.

The project builds fine, but when I attempt to open the view, I get the exception given below.

I've also tried making the object a companion object, but it didn't help.

Any idea what's missing?

Solution

  • Finally figured out a solution, adding @JvmStatic to the external object function solves it:

        @CheckedTemplate
    object Templates {
        @JvmStatic
        external fun new(): TemplateInstance
    }
