kotlinlang #eap

We’re testing Kotlin 1.6.20-M1 right now and I found one bug that hopefully can be addressed before the release: https://youtrack.jetbrains.com/issue/KT-51351

If you refrained from testing EAP Kotlin versions because you were using #compose, you'll be happy to see you know have an option to circuvment this problem.

The problem with applying free args as

ListProperty.convention(…)

is that once user sets their own value on the property (including using ListProperty.add/addAll
), convention is cleared/ignored, so also language settings are cleared for a user that configures

compilerOptions

in addition to

enableLanguageFeature()

Also Wasm tests do not work in other projects as well @bashor.

Another problem with VisionForge. After I changed all JS modules to MPP, gdml module fails to resolve dependencies with a strange error:

I checked that all dependencies are present in the repository. Also I do not understand, why versions are not shown. Project link: https://github.com/SciProgCentre/visionforge/tree/beta/1.9.0

1.9.0-Beta appears to have changed something about the intersection of KSP, JVM IR in stub gen, and possibly kotlin IC. Filed details and repro steps here: https://youtrack.jetbrains.com/issue/KT-59220

I still don't see 1.9.0 in Android Studio Giraffe betas, I'm worried we're not going to get to test the IDE support before release at this rate

Seems like ..< operator is not analyzed correctly by UAST, after update from 1.9.0-Beta to RC the expression type is reported as null. Filed https://youtrack.jetbrains.com/issue/KT-59564

Hey, is it expected, that latest

build is from week ago ? f.e. latest now is: https://maven.pkg.jetbrains.space/kotlin/p/kotlin/dev/org/jetbrains/kotlin/kotlin-stdlib/1.9.20-dev-4610/ (published on 2023-06-22)

Not sure if this is the right channel, but just in case, how can I disable the warning about language level 2.0 when using the

kotlin.experimental.tryK2=true

gradle property? I'm using

allWarningsAsErrors

so it currently breaks the build... 😕

Just trying out the new memory allocator

freeCompilerArgs.add("-Xallocator=custom")

and ran into this build error:

📢 Great news — the 🏆 Kotlin EAP Champions 🏆 program has yielded very positive results; we received a wealth of valuable feedback from our champions, which greatly assisted us in stabilizing Kotlin releases! We’re ready to expand the program and are on the lookout for new champions! At this time, we need champions who are developing these specific types of projects: • Kotlin Spring applications • Kotlin Compiler plugins • Kotlin libraries If you’re working on one of these types of projects, are ready to test your projects with K2, and want to become an EAP Champion — please fill out this form! If you’ve already filled it out but haven’t received a response, please ping me in DM. ℹ️ Learn more about who EAP Champions are and why being an EAP Champion is worthwhile..

Testing K2 and build output seems strange. It says:

##### 100% (220/220) tasks have been compiled with Kotlin 2.0 #####

But as expected all the kapt tasks says:

w: Kapt currently doesn't support language version 2.0+. Falling back to 1.9.

Is this normal or am I missing some parameters?

I've seen the 1.9.20 branch has been created. We're close to a beta it seems 👀

Just seen the 1.9.20-Beta changelog and there is quite a bit of stuff! I must admit tho that I'm scared of all the restrictions that seem to have gotten into KMP 🥲 Last compilation with -dev was fine, let's see the next

📣*Kotlin 1.9.20-Beta is here, with improvements on various fronts!* ✅ Multiplatform project configuration is now easier with the introduction of the new default hierarchy template in the Kotlin Gradle plugin. ✅ Multiplatform project build speed has improved significantly, thanks to the full support of the Gradle configuration cache. ✅ The Kotlin/Native memory manager performs better because the new memory allocator is enabled by default, and there are performance improvements for the garbage collector. ✅ We’re introducing a new target for Kotlin/Wasm –

wasm-wasi

. ✅ We’ve added support for the WASI API in the standard library, simplifying the use of Kotlin/Wasm beyond browsers. ✅ We’re working on stabilizing the K2 compiler, and we invite you to try it!

MPP projects now also have experimental project level and target level DSL for compiler options:

Copy code

kotlin {
     compilerOptions {
          // Project-level common compiler options that are used as defaults for all targets
          allWarningsAsErrors.set(true)
     }

     // Target-level compiler options
     jvm {
          compilerOptions {
               // JVM compiler options that are used as defaults for all compilations in this target
               jvmTarget.set(org.jetbrains.kotlin.gradle.dsl.JvmTarget.JVM_17)
          }
     }

    js {
        compilerOptions {
              // JS compiler options that are used as defaults for all compilations in this target
              moduleKind.set(org.jetbrains.kotlin.gradle.dsl.JsModuleKind.AMD)
        }
    }

    linuxX64 {
        compilerOptions {
             // Native compiler options that are used as defaults for all compilations in this target
             languageVersion.set(org.jetbrains.kotlin.gradle.dsl.KotlinVersion.KOTLIN_2_0) // Overrides default version ‘1.9’
        }
    }

    iosArm64 {
       compilerOptions {
            // Native compiler options that are used as defaults for all compilations in this target
            allWarningsAsErrors.set(false) // Overrides project-level configuration
       }
    }
}

And related

languageSettings

values are also synced with related compilation task

compilerOptions

. Please give it a try and provide feedback 🙂

Kotlin 1.9.20-Beta breaks IDE detection of some transitive dependencies for my jvmCommonTest source set, which is an intermediate JVM+Android source set. This occurs with either the 1.9.20-Beta or 1.9.0 IDE plugin. It detects some references (

kotlin.test.Test

), but not others (

kotlin.test.assert*

). Everything works at compile/run time.

kotlin.test

is an API dependency coming from a testing-support module. If I add the dependency directly to the module, the errors go away. This is a regression from Kotlin 1.9.10.

Another issue, this one caused by the 1.9.20-Beta Kotlin IDE plugin (232-1.9.20-Beta-release-242-IJ9559.62). Some `expect`/`actual` function calls annotated

@Throws

warn:

Annotation
@Throws(exceptionClasses = {<SomeException>::class})
is missing on actual declaration. All annotations from expect
fun <someFunction>() defined in ...
must be present with the same arguments on actual
fun <someFunction>() defined in ...
, otherwise they might behave incorrectly.

even though the

actual

is in fact annotated with the same exception class as the

expect

. This seems to occur when the exception class is defined as an

actual typealias

, but not in source sets where the exception is an

actual class

. Everything works at compile/run time. The warnings occur with either Kotlin 1.9.10 or 1.9.20-Beta, with the 1.9.20-Beta IDE plugin, but not with the 1.9.0 IDE plugin.
