java - 使用 Arquillian 和 ShrinkWrap 在抽象类中使用 ShrinkWrap 创建部署

Question

我试图通过定义一个抽象类来执行测试，它将使用 Arquillian 和 ShrinkWrap 为每个测试创建一个公共部署。在我的存储库中，我有一个 EntityManager，它执行 JPA 操作。UserRepository 和 CarRepository 是相同的（除了 User 和 Car）。UserRepositoryTest 和 CarRepositoryTest 相同。

但是， CarRepositoryTest 出于某种原因生成错误。你能帮我么？=)

public abstract class AbstractRepositoryTest {

        @Inject
        protected UserRepository userRepository;

        @Inject
        protected GroupRepository groupRepository;

        @Inject
        protected CarRepository carRepository;

        protected DummyGenerator dg;

        protected UserRepositoryFindQuery qUser;

        protected CarRepositoryFindQuery qCar;

        @Deployment
        public static final Archive<?> createDeployment() {

                File[] libs = Maven
                                .resolver()
                                .loadPomFromFile("pom.xml")
                                .resolve("org.apache.commons:commons-lang3",
