Невозможно собрать или упаковать kotlin Maven на основе проекта весенней загрузки

0 голосов
/ 08 апреля 2020

У меня есть kotlin проект весенней загрузки, этот проект - мой первый пример в kotlin, который я разработал. Я использую jpa и metamodel для построения запросов. когда я пытаюсь построить проект, я сталкиваюсь с сообщением об ошибке «не могу найти символ». Я приложил здесь исходный код. Может кто-нибудь построить мой исходный код и найти мою точную точку отказа. Я также добавил сущность Employee, классы репозитория и контекст файла pom. 

@Entity
@Table(name = "tblEmployees")
open class Employee : Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "employeeId", unique = false, nullable = false)
    var employeeId: Long? = null ;

    @Column(name = "EmployeeGuid", unique = true, nullable = false, length = 20)
    var employeeGuid: String? = null

    @Column(name = "FirstName", unique = false, nullable = false, length = 20)
    var firstName: String? = null

    @Column(name = "LastName", unique = false, nullable = false, length = 20)
    var lastName: String? = null

    @Column(name = "Role", unique = false, nullable = false, length = 20)
    var role: String? = null

    @Column(name = "RegisterServerIP", unique = false, nullable = false, length = 20)
    var registerServerIP: String? = null

    @Column(name = "RegisterClientIP", unique = false, nullable = false, length = 20)
    var registerClientIP: String? = null

    @Column(name = "RegisterDate", nullable = false)
    var registerDate: Int? = null

    @Column(name = "RegisterTime", nullable = false, length = 8)
    var registerTime: String? = null

    @Column(name = "RegisterDateComplete", nullable = false, length = 50)
    var registerDateComplete: String? = null
}

Вы должны использовать плагин компилятора Kotlin с плагином jpa, чтобы Kotlin и JPA-сгенерированная метамодель работали: 

<plugin>
    <artifactId>kotlin-maven-plugin</artifactId>
    <groupId>org.jetbrains.kotlin</groupId>
    <version>1.2.30</version>
    <configuration>
        <compilerPlugins>
        <plugin>jpa</plugin>
        </compilerPlugins>
        <jvmTarget>1.8</jvmTarget>
    </configuration>
    <dependencies>
        <dependency>
        <groupId>org.jetbrains.kotlin</groupId>
        <artifactId>kotlin-maven-noarg</artifactId>
        <version>1.2.30</version>
        </dependency>
    </dependencies>
    <!--...-->
</plugin>
