Kotlin在编译时未解决的参考
我前几天正在做一个项目，这个工作正在进行中，我今天又回来了，不再编译，但是我没有改变任何东西，据我所知…
这是文件：
package windall.console.account.api.persistence import com.fasterxml.jackson.annotation.JsonIgnore import windall.console.account.api.dtos.PaymentDto import windall.console.account.api.model.Tenant import java.time.LocalDateTime import javax.persistence.Column import javax.persistence.Entity import javax.persistence.GeneratedValue import javax.persistence.Id import javax.persistence.JoinColumn import javax.persistence.ManyToOne @Entity data class Receipt ( @Id @GeneratedValue(strategy = GenerationType.IDENTITY) val id: Long? = null, val amount: Long, @JsonIgnore @ManyToOne(fetch = FetchType.EAGER) @JoinColumn(name = "tenant_id") val tenant: Tenant? = null, @Column(name = "payment_datetime") val paymentDateTime: LocalDateTime = LocalDateTime.now() ) { @Suppress("unused") private constructor(): this(amount = 0) constructor(dto: PaymentDto, tenant: Tenant) : this(amount = dto.amount, tenant = tenant) } 这是我在我的maven构建中的错误：
> [ERROR] Failed to execute goal org.jetbrains.kotlin:kotlin-maven-plugin:1.1.60:compile (compile) on project api: Compilation failure: Compilation failure: > [ERROR] C:\workspace\windall.console.account.api\src\main\kotlin\windall\console\account\api\models\Receipt.kt:[18,30] Unresolved reference: GenerationType > [ERROR] C:\workspace\windall.console.account.api\src\main\kotlin\windall\console\account\api\models\Receipt.kt:[18,30] An annotation parameter must be a compile-time constant > [ERROR] C:\workspace\windall.console.account.api\src\main\kotlin\windall\console\account\api\models\Receipt.kt:[24,22] Unresolved reference: FetchType > [ERROR] C:\workspace\windall.console.account.api\src\main\kotlin\windall\console\account\api\models\Receipt.kt:[24,22] An annotation parameter must be a compile-time constant
任何帮助将是奇妙:)因为我似乎无法find这些错误的任何可能的原因，我的IDE也没有突出任何问题…
如果有帮助，这里也是我的pom

我错过了import
import javax.persistence.GenerationType import javax.persistence.FetchType
结果eclipse不能识别Kotlin中的注解参数中使用的类，因此，清理导入任务删除了它们…
