Referencia no resuelta de Kotlin en time de compilation

Estuve trabajando en un proyecto hace unos días y funcionaba, volví a hacerlo hoy y ya no compilo, pero no cambié nada por lo que sé …

Este es el file:

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) } 

Aquí está el error que estoy obteniendo en mi construcción maven:

 > [ERROR] Failed to execute goal org.jetbrains.kotlin:kotlin-maven-plugin:1.1.60:compile (compile) on project api: Comstacktion failure: Comstacktion 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 

Cualquier ayuda sería maravillosa 🙂 ya que parece que no puedo encontrar ninguna causa posible para estos errores, mi IDE tampoco resalta ningún problema …

También aquí está mi pom en caso de que ayude
