Kotlin 2.0 support

[rorbech]

The Realm Kotlin plugin is not compatible with K2.

Trying to build https://github.com/realm/realm-kotlin-samples/tree/main/Intro with 2.0.0-Beta2 yields:

There are some plugins incompatible with language version 2.0:
  io.realm.kotlin.compiler.Registrar
Please use language version 1.9 or below

[rorbech]

Update SDK code base to support compilation with K2 in #1721

[dhng22]

Any plan for a version that supports Kotlin 2.0?

[rorbech]

@dhng22 With #1721 the SDK will actually compile with K2, but due to binary compatibilities we will have to ship separate distributables for 1.9 and 2.0. The intention is to make a branch compiled with K2 with a version suffix until things settles or we find another path. Intention is that this will happen within a week or three.

[dhng22]

@rorbech If there's any progress or change, please let me know, I'd love to track it

[toaster217]

Is there any progress?

[pkumar8888]

Hi guys, we've been waiting for this one as well. Any updates? As of now v1.16 also does not offer support for K2.

[dhng22]

Any updates after 1 month?

[lehieu2602]

Any update? K2 has just released

[matsudamper]

When will 2.0.0 be released? https://search.maven.org/artifact/io.realm.kotlin/gradle-plugin

[toaster217]

Issue closed, ReadMe updated to Realm 2.0.0 but Realm 2.0 isn't actually rolled out yet

[yannickpulver]

Latest 2.0.0-SNAPSHOT is compatible with Kotlin 2.0 if you don't want to wait for the stable release. In README.md is a guide how to switch to snapshots

@bidadh It seems like the providers for version catalogs doesn't resolve plugins from the classpath, so you have to apply the plugin with

id("io.realm.kotlin")

instead of by alias or similar constructs. There is a PR in our samples repository showing this.

Is there any update?

@Ash-333 There is no fixed date for when the 2.0.0 release will go out, but until that you can use the 2.0.0-SNAPSHOT following the instructions in the README.

I am trying to use realm for KMP project targeting Android, iOS & Desktop

@rorbech It didn't work either. I've tried many options already and have had no success so far. I've decided to wait until 2.0.0 is released unless there is a clear way. When should we expect 2.0.0?

[maicol07]

I've found a way to get it to work. It seems the gradle plugin doesn't follow the classic gradle plugin name convention and it can't be resolved (i.e. tries to download it from https://oss.sonatype.org/content/repositories/snapshots/io/realm/kotlin/io.realm.kotlin.gradle-plugin/2.0.0-SNAPSHOT/maven-metadata.xml which gives 404).

The objective is to let it download the plugin from https://oss.sonatype.org/content/repositories/snapshots/io/realm/kotlin/gradle-plugin/2.0.0-SNAPSHOT/maven-metadata.xml

Following the README I've found the working combination:

Project build.gradle.kts (root) Remove the plugin from the plugins block and add the following:

buildscript {
    dependencies {
        classpath("io.realm.kotlin:gradle-plugin:2.0.0-SNAPSHOT")
    }
}

Module build.gradle.kts Ad the following to the plugins block:

id("io.realm.kotlin")

[bidadh]

@maicol07 you still need to add repositories to your module's build.gradle.kts

repositories {
  maven {
    url = uri("https://oss.sonatype.org/content/repositories/snapshots")
  }
}

Yeah, I have implied it

I've just seen that 2.0.0 was released yesterday 🙂 https://github.com/realm/realm-kotlin/releases/tag/v2.0.0

@bamsbamx Which version did you migrate from? And did you also remember to update the version of the realm-depenedencies?

@bamsbamx Which version did you migrate from? And did you also remember to update the version of the realm-depenedencies?

My bad, I updated from 1.8.0, but just forgot to also update the dependencies. After updating, everything went ok:

io.realm.kotlin:library-base io.realm.kotlin:library-sync
