Hello! I don't know what's going on, can anyone help me? I have this error: Class 'Customer' should have [public, protected] no-arg constructor. I have both plugins:

plugins {
    kotlin("jvm") version "2.0.21"
    kotlin("plugin.spring") version "2.0.21"
    id("org.springframework.boot") version "3.3.5"
    id("io.spring.dependency-management") version "1.1.6"
    kotlin("plugin.jpa") version "2.0.21"
}

As far as I understand, kotlin("plugin.jpa") should contain the compiler plugin with no arguments, but maybe I'm wrong.

https://kotlinlang.org/docs/no-arg-plugin.html#jpa-support that applies to @Entity @Embeddable and @MappedSuperclass annotated classes - is your Customer one of them?

[TomasWild]

Yes, @Entity

[ephemient]

hmm. where is this error coming from?

[ephemient]

I don't see a way to easily debug the compiler plugin

[ephemient]

however, if the code builds fine in Gradle, but the IDE shows error, then you're probably running into https://youtrack.jetbrains.com/issue/KTIJ-31154/K2-No-arg-JPA-compiler-plugin-seems-not-work-on-Kotlin-Plugin-K2-mode
