Kotlin unresolved reference at compile time - maven

Question

I was working on a project a few days ago and it was working, I came back to it today and it is no longer compiling but I didn't change anything as far as I know...
This is the 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)
}
Here is the error that I am getting in my maven build:
> [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:[24,22] An annotation parameter must be a compile-time constant
Any help would be marvelous :) as I can't seem to find any possible cause for these errors, my IDE also is not highlighting any issues...
Also here is my pom in case it helps

Answer 1

I was missing the imports
import javax.persistence.GenerationType
import javax.persistence.FetchType
Turns out eclipse won't recognize the Classes used in annotation parameters in Kotlin, therefore, the cleanup import task removed them...
