Я пытаюсь выполнить крошечную poc (операцию добавления в задачу сельдерея) с помощью Kotlin -> сельдерей ->> python.

Python->сельдерей->>Python в порядке. Но с https://github.com/crabhi/celery-java и этот «неправильный» код:

 package poc_kotlin_celery                                        
                                                                 
import com.geneea.celery.*                                       
                                                                 
fun main() {                                                     
   val client: Celery = Celery.builder()                         
        .brokerUri("amqp://localhost//")                       
        .backendUri("rpc://localhost//")                       
        .build();                                                
                                                                 
   val args = arrayOf(1, 2)                                      
   val result: AsyncResult<Int> = client.submit("task.add", args)
   val suma: Int = result.get() as Int                           
                                                                 
                                                                 
   println(suma as Int);                                         
}                                                                
 

Я не могу исправить ошибки компиляции:

 $ gradle run
