/ 27 сентября 2019

У меня есть общая библиотека JNI, написанная на C, и соответствующий класс Java в одном проекте maven, и приложение, использующее этот класс в другом проекте.Я использую Nar-Maven-плагин для обработки JNI.Версии: Maven 3.6.0 Java 12 плагин nar 3.6.0 Я использую интеграционные тесты 3 и 4, которые поставляются с nar-maven-plugin в качестве примера.Для него 3 я только что обновил POM, чтобы он был автономным и работал с Java 12:

Теперь я использую его урезанную версию 4 для проверки, это файл Java src/main/java/it0004/Hello.java

package it0004;

import it0003.HelloWorldJNI;

public class Hello {
    public static void hello()
    {
        HelloWorldJNI.sayHello();
    }
}

Обратите внимание, что это POM обрабатывает только компиляцию.Зависимость указывается с <type>nar</type>, так что зависимость найдена.Но файла nar нет в classPath, поэтому компиляция не удалась.Выходные данные из mvn -X compile содержат

Как видно, файл nar зависимости не находится в classPath, поэтому компиляция завершается неудачно, поскольку он не может найти класс зависимости.Как мне убедиться, что файл nar включен в classPath?
