Сбой именованной аннотации в jar и source

1

проблема с проектом openkad, но может быть проблемой в виде guice/environment:

gist - это код, использующий Guice для:

@Provides
@Singleton
@Named("openkad.rnd") 
Random provideRandom(@Named("openkad.seed") final long seed) {
        return seed == 0 ? new Random() : new Random(seed);
    }

однако @Singleton и @Named ("openkad.rnd") помечены компилятором как неправильное размещение.

и, видимо, правильно, так как названная аннотация нацеливает поле, а не метод:

/**
 * Annotates named things.
 *
 * @author [email protected] (Bob Lee)
 */
@Retention(RUNTIME)
@Target({ ElementType.FIELD, ElementType.PARAMETER })
@BindingAnnotation
public @interface Named {
  String value();
}

Чтобы воссоздать:

  1. Создайте Java-проект в eclipse, используя JDK 1.6 или 1.8, предназначенные для разных периодов времени выполнения
  2. Включение зависимостей через pom (пример от 1 до 4)
  3. Использование тестовых модулей запуска исходного кода или openkad r60 (https://code.google.com/p/openkad/)

Каков ожидаемый результат? Что ты видишь вместо этого?

Успех для всех UT, но я вижу это вместо этого:

    Guice 3 позволяет @Named по методам . Попробуйте mvn dependency:tree -Dverbose чтобы увидеть, используется ли конфликтующая версия Guice.

    Вот и все, спасибо, что заставили меня посмотреть туда!
