kotlinlang #gradle

Good evening, I have upgraded our multiplatform project from 1.3.72 to 1.4 following the migration guide on kotlinglang. Everything went pretty smooth except that for one project/module where the task ompileKotlinJshangs without any errors or warning. There is no particular difference between the modules and I have no ideas left. Is there a way to debug the gradle task in order to understand what´s happening?

I'm on a project, where every new module I add, it creates the path

/src/java

and

/src/kotlin

. Where do I change this setting, so that it stops automatically creating that path?

Is there a new Kotlin Gradle plugins dependency coming out for Kotlin 1.4.0?

implementation("org.gradle.kotlin:plugins:1.3.6")

is causing incompatibilities with the 1.4.0 Kotlin Gradle plugin because it depends upon 1.3.72. I don't see a newer version out.

I recently started noticing that if I try to run Kotest JUnit5 tests class, I am getting this error: org.junit.platform.commons.JUnitException : TestEngine with ID ‘kotest’ failed to discover tests. Any ideas on this?

Hi everyone, we need some suggestion around

kts

usage for gradle build. We have 140+ modules and we started migrating to

kts

from groovy. But our configuration time on CI with fresh project has increased a lot. One

kts

file takes almost 1.5 seconds to compile. So it is not scalable, it is not parallel or it doesnt support remote cache. I wonder, is there any planned significant improvement or should we migrate back to groovy?

Hi everyone! Is it ok to get this error (look at the screenshot) on a fresh project (just created in Idea)? Is there any way to fix it?

But as soon as I depend on the client and server builds from the 'master' build, their own tasks appear to be inaccessible 🤔

I'm trying to upgrade to Kotlin 1.4, but I'm getting strange problems with jar's in classpath

w: Runtime JAR files in the classpath should have the same version. These files were found in the classpath:

Any idea why this may happen?

Anyone tried to create a precompiled plugin with android library (agp 4.2.0-alpha08) and kotlin multiplatform plugin (1.4.0)? I am having problem with all the functions used by the multiplatform plugin (sourceSets, implementation, etc)

Hi, I have a beginning of a mono repo which contains 3 apps with shared code. In android studio when I hit the green hammer, all apps are built. This is okay when I want it, but usually is a waste. I can get around it to have a separate settings.gradle on hand, but its kind of annoying to copy paste, and remember not to commit etc

I want to update a multi-project build to 1.4.0 and cannot get the gradle configuration to work. I keep getting

org.gradle.cache.CacheOpenException: Could not open cache directory a12qv6mvmtxif3x5d88rky5rk (C:\Gradle\caches\6.6\gradle-kotlin-dsl\a12qv6mvmtxif3x5d88rky5rk)

which is caused by

Caused by: java.lang.IllegalArgumentException: org.gradle.api.internal.initialization.DefaultClassLoaderScope@7c5064e5 must be locked before it can be used to compute a classpath!

I tried delting the content of

/build

folders in all projects/subprojects and all caches in

C:\Gradle\caches\

. Found this: https://github.com/gradle/gradle/issues/4823 But to the best of my knowledge, configure-on-demand isn't a thing anymore and I think that i am not using

evaluationDependsOn

I don't know how to proceed from here.

Good morning, is there a way to check IDE version from Gradle? I got a multiplatform project and script for import modules/composite-builds in my

gradle.settings.kts

, but the following problem: • Android Studio doesn’t work well with multiplatform projects yet • Cannot use IntelliJ because I got an Android module with Compose and AGP 4.2, so I got

This version of the Android Support plugin for IntelliJ IDEA (or Android Studio) cannot open this project, please retry with version 4.2 or newer.

So I’d like to exclude that Android module when I’m on IntelliJ

Hi, all Is there any place that I can find which Gradle version should I use based on my AGP?

Does creating a kotlin src folder have any benefits? And use like this:

sourceSets.all {
    java.srcDir("src/$name/kotlin")
}

Hello all Does possibility exist to import kt-file into build.gradle.kts ?

is there a way to always get the latest version of the Kotlin plugin, something like this maybe?

plugins {
    application
    kotlin("jvm").version("latest")
    maven
}

Hi all - can code built in

buildSrc/src/main/kotlin

access a constant in

buildSrc/build.gradle.kts

? At the moment I have

plugins {
  kotlin("jvm") version "1.4.10"
}

buildSrc/build.gradle.kts

and

const val kotlinVersion = "1.4.10"

buildSrc/src/main/kotlin/DependencyVersions.kt

and having to change two files to update kotlin universally rather than one is irritating me.

How do I make sure that opening and closing braces have same indentation. Do I need to use any regex for this or is there any rule available? Example :

//INCORRECT 

viewModel.liveData.observe(this, Observer {
launch(url(
            locale = Locale.getDefault().language,
            appName = APP_NAME), window.decorView.rootView) })

//CORRECT

viewModel.liveData.observe(this, Observer {
launch(
            url(locale = Locale.getDefault().language,  appName = APP_NAME), 
            window.decorView.rootView
      ) 
    })

I’ve uploaded my own library over github packages : https://github.com/BeiningBogen/statemachine/packages/398001 Now I’m trying to use it from an android app like so :

allprojects {
    repositories {
        google()
        jcenter()
        maven {
            name = "GitHubPackages"
            url = uri("<https://maven.pkg.github.com/beiningbogen/statemachine>")
            credentials {
                username = project.extra["gpr.user"].toString()
                password = project.extra["gpr.key"].toString()
            }
        }
    }
}
...
dependencies {
    implementation("no.beiningbogen.StateMachine-jvm:statemachine-jvm:0.1.1")
}

but I keep getting

Failed to resolve: no.beiningbogen.StateMachine-jvm:statemachine-jvm:0.1.1

Is there a specific thing I need to do with the kotlin dsl to be able to use Maven Pom style dependencies?

Hi everyone! I am in the process of switching my libraries to Kotlin 1.4.10. One of these used annotation processing. And now the task :kaptKotlin fails with the following error:

> Task :meta:kaptKotlin FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':meta:kaptKotlin'.
> java.util.zip.ZipException: error in opening zip file

I am using gradle 6.6.1.

Kotlin:       1.3.72

Does anyone have an idea what is going on? I somehow suspect, that the jar file is not created and can therefore not be opened. What should I look for in the gradle logs? Does it matter that the Kotlin version packaged with gradle is 1.3.72?

I get this build error:

Cannot resolve external dependency org.jetbrains.kotlin:kotlin-stdlib-js:1.4.10 because no repositories are defined.

In my gradle.build.kts file, I actually have not even specified the version:

implementation(kotlin("stdlib-js"))

how can I fix this issue?

So I defined a property in

gradle.properties

file and got a reference in the

build.gradle.kts

file by declaring a global property:

val api_key: String by project

I want to use

api_key

in my

Main.kt

, but I can't seem to figure out how to gain access. Searched on StackOverflow and all the results were android related. Can anyone help?

As I upgraded a project to use Kotlin 1.4.10 instead of 1.3.60, I got errors because of a version mismatch (stemming from a library that used 1.3.60). I had to solve it by adding this dependency:

implementation "org.jetbrains.kotlin:kotlin-reflect:1.4.10"

I would love for the version string here to not contain another hardcoded "1.4.10", but to use whatever the plugin version is at. Is there anyway to do this? We use Groovy Gradle.

Are there examples on how we can use common gradle kts files across other gradle files? Typically, I would apply the kotlin jvm plugin in subprojects and do some configurations. However, if I don’t apply the same plugin in the module specific gradle file, it won’t recognize jvm methods such as

implementation

. Is there a way around that?

Allan Wang

For gradle plugins, is it possible to auto generate

resources/META-INF/gradle-plugins/

from a dsl under

build.gradle

? Similar to how jar creation can specify the manifest info in

build.gradle

Hi, Im trying to build my Android app in AppCenter and its failing because my main app module is called

my_app

and not

app

How can I configure my

settings.gradle

to allow my

my_app

module be an alias for

app

why isnt this enough ?

project(':my_app').projectDir = new File(settingsDir, 'app')

Hello all 👋. I've recently ran into an issue where contents of the

buildSrc

folder can no longer access the Gradle api. For example:

//directory: buildsrc/src/main/kotlin/Util.kt

import org.gradle.api.*

fun Project.foo() = doBar()

Project

comes up as unresolved. I recently updated to Kotlin 1.4.10 and Gradle 6.6.1, and this is a multi-module project. The `buildSrc`'s

build.gradle.kts

file is as it's always been, no changes:

plugins {
    `kotlin-dsl`
}

repositories {
    jcenter()
}

Any idea what might have caused this, and how I might resolve it? When I try to access

project.foo()

from a separate module's

build.gradle.kts

file, it hits me with a:

Overload resolution ambiguity. All these functions match.

error, and then when I try to go to the declaration it wants me to choose between the actual file that it's declared in (

buildSrc/src/main/kotlin/Util.kt

), and the decompiled java class file. I suspect some change was made in Gradle 6.6.1 with buildSrc dependencies or something but cannot for the life of me figure out what that might be that could be causing this. I've tried explicitly adding the

gradleApi()

dependency as well, but no dice. Any help would be appreciated!
