java.lang.UnsatisfiedLinkError 在 Kotlin 中使用 Qute TypeSafe 模板时

Question

当尝试将 Quarkus Qute Typesafe Templates 与 Kotlin 一起使用时（根据下面的代码将静态 class 转换为对象），我运行进入运行处的 UnsatisfiedLinkError时间.

问题代码：

@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()
    }
}

模板在 resources/templates/SubscriberResource/new.html 中可用。

项目构建良好，但当我尝试打开视图时，出现下面给出的异常。

我也试过将对象设为 companion 对象，但没有用。

知道缺少什么吗？

终于想出办法了，在外部对象函数中加入@JvmStatic就解决了：

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