We’re running into a regression between M2 and M3. M2 works fine. https://youtrack.jetbrains.com/issue/KT-40214

Hello! Can someone explain if it is possible to determine from the Kotlin plugin version whether this is an EAP version? For example, how to determine that 1.4-M3-release-IJ2020.1-1 is the EAP version, and 1.3.72-release-IJ2020.1-1 is the stable version?

Hi! How do I generate an executable file from JS? I have

kotlin {
    js(IR) {
        nodejs()
        binaries.executable()
    }
}

as my setup, and when running

build

it outputs a JS file to

build/js/packages/...

, but files from

resources

are nowhere to be found over there. What's the proper way to generate a executable file that works on its own?

I’m attempting to build our repo with 1.4-M3, but get a strange compile error on a random bit code

The feature “unit conversion” is disabled

private class OnJobDone(
    private val jobDone: (Job) -> Unit,
    val allDone: () -> Unit
)

private val callbacks = OnJobDone(
    jobDone = jobToChannelId andThen trackChannelSynced,
    // Fails on the next line
    allDone = {
      // ...
    }
)

Hi! Please, about 1.4-M3, I would be very grateful if someone could confirm if this a mistake from transitive dependencies:

According to https://kotlinlang.org/eap/#build-details the compatible version of

kotlinx.coroutines

is

1.3.7-1.4-M3

.

i updated my idea plugin to 1.4.0-rc and now its complaining that my kotlinx.serialization core is too old. I’ll just go back to the stable plugin for now. Probably a good idea to not update the plugin until the rc release cycle is complete.

With new RC build, we have problem using object classes with inline class when they are called from Java classes. Apparently, methods in object class gets some sort of hash

getAPP_ENTRY_8z4Jxt8

,compiler fails to find

getAPP_ENTRY

from java code. This only happens when return type is inline class. What could be root cause?

I went to setup the 1.4.0-RC, and it looks like the documentation is wrong. It refers to

1.4-RC

as the version, but what worked was

1.4.0-rc

. May be worth updating

We’re using Kotlin serialization

0.20.0

. Until now there has always been a preview build, e.g.

0.20.0-1.4-M3

. With the RC there’s only

1.0-M1-1.4.0-rc

. I’d just like to confirm whether this is intentional and if Kotlin Serialization will reach 1.0 with the final 1.4 release? We’d like to avoid milestone releases in production.

With 1.4 around the corner thanks to 1.4-RC, is there new documentation about the new IR compiler plugins APIs? Not sure what is up-to-date out there

Is there a

kotlin-dsl

version for Kotlin 1.4.0-rc?

Will Kotlin 1.4 support building iOS frameworks that can also be used to target Mac Catalyst? And if not, is there any hack to make this work in the meantime? (cc @Thomas)

Is it a feature of Kotlin 1.4 that I don’t have to specify

<*>

when casting to the generic

GraphEnumDefinition

? Or a bug? 😄 It’s inferred correctly.

when i am trying to add the kotlinx.nodejs dependency gradle says

Could not find org.jetbrains.kotlin:kotlin-stdlib-js:1.4.0-rc-KT-40650.

required by org.jetbrains.kotlinx:kotlinx-nodejs:0.0.4

the repo only mentions

jcenter()

as required repo

Upgraded to 1.4-rc and now Android studio complains about

viewModels

I didn't change my code at all. I tried clean and rebuilding with no luck

Hi! Please, I don't know if the following behavior is expected with `1.4.0-rc`: two equal KotlinType with the same delegate and abbreviation are considered different now. However, they were considered equal with

1.3.x

. I provide screenshots in the thread. Thanks in advance!!

Hi All, I was just wondering if anyone has faced the build process going in a loop when using kotlinx.serialization?

Hi All, tried Kotlin 1.4.0 on existing code (working in 1.3.72), got this error class instantiation (object), not sure what is the issue or how to debug “Exception in thread “main” java.lang.NoClassDefFoundError: kotlin/KotlinNothingValueException”

Hello All. I'm trying Debugging Coroutines feature. If I run with Idea standard runner - everything OK, I see coroutines states. (see screenshot) If I run with Gradle - I get "No coroutine information found". (see screenshot) Does Debugging Coroutines work with Gradle?

Crossposting as probably tied to Kotlin 1.4 : I'm getting a very weird issue and wonder if someone have already seen that, before trying to find a small repro. On some suspending functions an Android

TextView.getText().toString() == ""

works but

TextView.text.toString() == ""

(As suggested by IDE and previously worked) triggers

java.lang.ClassCastException: android.text.SpannableStringBuilder cannot be cast to java.lang.String

. It's like in the second case the .toString() call is converted to a cast and not the proper toString()

Where are the dev build for Kotlin

1.4.30

published? I see them here already: https://github.com/JetBrains/kotlin/releases But I can’t find them here: http://dl.bintray.com/kotlin/kotlin-dev/org/jetbrains/kotlin/jvm/org.jetbrains.kotlin.jvm.gradle.plugin/

can we expect an official EAP for 1.4.20 ? (I want to switch to kotlin 1.4 https://youtrack.jetbrains.com/issue/KT-41429)

1.4.20-M1 is available! It’s available in the 

kotlin-eap

 Bintray repository and EAP IDE plugin channel. What’s new: https://kotl.in/1.4.20-M1

On my side, the upgrade is not smooth at all, the IDE ignores the modifiers most of the time until I edit the code and revert changes. I reported the issue here 2 days ago (with screenshots and details), but it hasn't been assigned yet: https://youtrack.jetbrains.com/issue/KT-42274 Can it be looked into? I'm wondering if it's caused by changes that are designed to improve performance, which would do it at the expense of correctness… and UX in the end.

Am I the only one getting blinking autocomplete popup that prevents one from selecting any entry in 1.4.20-M1?

Hi Dear Kotlin Team, Can https://youtrack.jetbrains.com/issue/KT-42501 be marked as top priority and targeted at 1.4.20? That regression introduced in 1.4.20-M1 is making developing a nightmare as autocomplete is nearly unusable.

1.4.20-M2 is available! It’s available in the 

kotlin-eap

 Bintray repository and EAP IDE plugin channel. What’s new: https://kotl.in/1.4.20-M2

Hi, yesterday I spend some time for a leak in our application. it turn out collected item is not cleared from Channel. I found KT-16222 as fixed in 1.4.20-M1 but provided sample code and our own code still leaks and don’t clean up. I tested with both M1 and M2. (Our issue is much more similar to linked KT-33986). I am looking at the source code to find out any test for those issues. KT-16222 should be open again if it is not fixed yet.

Hey guys, I have noticed that 1.4.20-M1 is on central. This is on purpose, or at least it is fully deployed and usable?
