UnsatisfiedLinkError при попытке использовать google or-tools с пружиной

/ 13 апреля 2020

Мне нужно написать простую службу TSP-solver для моего проекта.

Решатель or-tools работает с простым классом stati c, но когда я пытаюсь включить его как сервис весной, я получаю java .lang.UnsatisfiedLinkError: 'void com.google.ortools.constraintsolver.mainJNI.swig_module_init ()' 

public class TravelingSalesmanExample2 {
    public static void main(String[] args) {
        System.loadLibrary("jniortools");
...

работает отлично, но когда я пытаюсь вызвать методы из or- инструменты внутри пружины обозначаются как @ Service или даже как этот 

@SpringBootApplication
public class Application {
    public static void main(String[] args) throws IOException {
        SpringApplication.run(Application.class, args);
        TravelingSalesmanExample2.main(null);
    }
}

У меня есть эта ошибка

Я попытался добавить или инструмент как зависимость maven как здесь описано https://github.com/oliviercailloux/google-or-tools-java

попытка добавить аргумент -Djava.library.path=/Users/vitaliy/Desktop/backend/lib

попытка загрузки как System.load("/Users/vitaliy/Desktop/backend/lib/libjniortools.jnilib");

, но не удалось , Любая идея, как сделать родные библиотеки видимыми для приложения на пружине?

ОС UPD: ma c os catalina 10.15.3
