e: org.jetbrains.kotlin.backend.common.BackendException: Backend Internal error: Exception during Experimental parallel IR backend #981

Open ohyooo opened 2 years ago

ohyooo commented 2 years ago

I'm migrating a project from realm-java to realm-kotlin. after fixing all build error I got this. I was able to build a KMM module but it breaks some heavy logics, so I have to only change as little as possible, just for compatibility.

> Task :app:compileDevelopmentDebugKotlin
'compileDevelopmentDebugJavaWithJavac' task (current target is 11) and 'compileDevelopmentDebugKotlin' task (current target is 1.8) jvm target compatibility should be set to the same Java version.

Realm: 1.0.2 (tried snapshot) compileSdkVersion = 32 (tried 33) buildToolsVersion = "32.0.0" minSdkVersion = 19 targetSdkVersion = 32 gradle = 7.5.1

The error msg said that I have a problem with RealmFragment. Actually, if I removed this Fragment, it will throw another file for same reason. The error shows on desktop (windows 11), laptop(windows 10) and CI(some kind of Linux). So I guess it's not system related.

there's a issue #935 , but I didn't use realm-java.

If you need any other infomation please let me know

cmelchior commented 2 years ago

Hi @ohyooo Can you post your RealmFragment class? It might be a problem with how it uses companion classes, which our compiler plugin doesn't handle correctly

ohyooo commented 2 years ago

@cmelchior

I just figured out how to reproduce with minimal codes

try this:

import io.realm.kotlin.types.RealmObject

open class BaseFragment<T : RealmObject>

class RealmFragment : BaseFragment<RealmObject>()

If I pass Dog as generic type, it works

import io.realm.kotlin.types.RealmObject

open class BaseFragment<T : RealmObject>

class RealmFragment : BaseFragment<Dog>()

class Dog: RealmObject
edualonso commented 2 years ago

Hi @ohyooo. We can reproduce the error. It appears our compiler plugin wrongly identifies RealmFragment as a subclass of RealmObject. We will try to devise a fix for this.
