Hello everyone 🙂 , I have a question I can’t generate jar for my kotlin application. And I have a

build.gradle.kts

and I expected `build/libs/app-SNAPSHOT.jar`: (The .jar file does not generate for me)

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

plugins {
	id("org.springframework.boot") version "2.2.6.RELEASE"
	id("io.spring.dependency-management") version "1.0.9.RELEASE"
	kotlin("jvm") version "1.3.71"
	kotlin("plugin.spring") version "1.3.71"
	kotlin("plugin.jpa") version "1.3.71"
}

group = "com.warlock"
version = "0.0.1-SNAPSHOT"
java.sourceCompatibility = JavaVersion.VERSION_11

repositories {
	mavenCentral()
}

dependencies {
	implementation("org.springframework.boot:spring-boot-starter-data-jpa")
	implementation("org.springframework.boot:spring-boot-starter-data-rest")
	implementation("org.springframework.boot:spring-boot-starter-web")
	implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
	implementation("org.jetbrains.kotlin:kotlin-reflect")
	implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
	runtimeOnly("org.postgresql:postgresql")
	testImplementation("org.springframework.boot:spring-boot-starter-test") {
		exclude(group = "org.junit.vintage", module = "junit-vintage-engine")
	}
}

tasks.withType<Test> {
	useJUnitPlatform()
	testLogging.events( "passed", "skipped", "failed", "standardError")
}

tasks.withType<KotlinCompile> {
	kotlinOptions {
		freeCompilerArgs = listOf("-Xjsr305=strict")
		jvmTarget = "11"
	}
}

If I want to build an app ("to check if it builds") but not create an apk binary, what do I want? assemble seems to create the apk

and -- if it needs to compile the code anyways, is there some palpable time it takes to create the apk?

Hello guys, I have a Kotlin-JVM lib published on Bintray ( let’s call it

myLib

) and a Gradle plugin. Plugin got

myLib

as dependency and

example

is using the Plugin, but I got

> Failed to apply plugin [id 'studio.forface.easy-publish']
   > Could not create an instance of type studio.forface.easygradle.publish.EasyPublishExtension.
      > Could not generate a decorated class for type EasyPublishExtension.
         > studio/forface/easygradle/internal/ConfigReadWriteProperty

ConfigReadWriteProperty

is part of

myLib

and

EasyPublishExtension

is something like:

abstract class EasyPublishExtension @Inject constructor(project: Project) {

    var username by project("", propertyName = "bintray.user")
    
    private operator fun <T : Any> Project.invoke(
        default: T,
        propertyName: String? = null,
        envName: String? = null
    ) = object : ConfigReadWriteProperty<EasyPublishExtension, T>(
    ....

}

What is the problem here?

Hello guys, My Build type beta fails on my build-gradle.kts on my Android project with error: BuildType with name ‘beta’ not found.

Noticed when trying to upload a Kotlin Native library to Bintray that the version is created but there are no files. What is needed in a build.gradle.kts file to include the missing files?

Hi I need help with the following error:

How can I convert this to kotlin dsl?

include ':library'
project(':library').projectDir = new File(settingsDir, '../MyLibrary/library')

I don’t find any info on how to set the project path with kotlin

Hey im having some trouble configuring the kotlin compile java version using the kotlin dsl for gradle. I cant seem to find

kotlinOptions

. Im using gradle version 6.5

Hi, I'm trying Cloudflare workers with Kotlin but they have a traditional build.gradle that I naturally want to convert to .kts The whole file is https://github.com/cloudflare/kotlin-worker-hello-world/blob/master/build.gradle and it is very basic except one crucial hack that merges a string with a file:

/* Kotlin js output assumes window exists, which it won't on Workers. Hack around it */
(new File("$projectDir/index.js")).text = "const window=this; " + file("$projectDir/build/distributions/${rootProject.name}.js").getText()

How do I write this in build.gradle.kts?

File("$projectDir/index.js").text

Where .text seem to be some kind of extension to the File object that is not available in Kotlin? PS. I don't know why they use kotlin.target.browser and not target.nodejs but maybe it is to get access to org.w3c.* stuff. Thanks!

Hello, error when trying to use a class from another module:

e: /home/StudioProjects/sample-multimodule/f_main/src/main/java/com/company/projectName/feature/main/home/HomeViewModel.kt: (4, 39): Unresolved reference: di

in my vm class:

package com.company.projectName.feature.main.home

import com.company.projectName.domain.di.DomainModule

class HomeViewModel() : HomeContract.ViewModel {

    val x = DomainModule.get()
}

I connected the module in dependencies:

dependencies {
    applyDependencies(depends)
    implementation(project(":domain"))
}

and when writing the code, all references to the classes of this module work, but errors occur during assembly. while in the

app

module the link to this class works. what do you think could be the problem?

do you think this module structure is normal or are there better options?

After upgrading to Gradle 6.x sometime ago I started to notice that after each and every build of my Kotlin project, Gradle generates Java source folders _unnecessarily_: •

src/main/java

•

src/test/java

My current configuration is:

$ ./gradlew -v
------------------------------------------------------------
Gradle 6.5.1
------------------------------------------------------------

Build time:   2020-06-30 06:32:47 UTC
Revision:     66bc713f7169626a7f0134bf452abde51550ea0a

Kotlin:       1.3.72
Groovy:       2.5.11
Ant:          Apache Ant(TM) version 1.10.7 compiled on September 1 2019
JVM:          11.0.8 (<http://Amazon.com|Amazon.com> Inc. 11.0.8+10-LTS)
OS:           Linux 5.4.0-42-generic amd64

I added the following to my

build.gradle.kts

script but had no effect whatsoever:

sourceSets {
    main {
        java.srcDir("src/main/kotlin")
        resources.srcDir("src/main/resources")
    }
    test {
        java.srcDir("src/test/kotlin")
        resources.srcDir("src/test/resources")
    }
}

Subprojects: They each create a build folder typically and then the parent has a build folder too but mine is essentially empty; I assume there is someway to like, start pulling from subprojects to populate the parent build folder? Does any of this make sense or am I crazy? Trying to find documentation on this or clarity what's really expected.

I saw this error multiple times, but I didn't see in the docs we should use

on

, it said

true

. Is this a typo?

org.gradle.unsafe.configuration-cache=true

https://docs.gradle.org/6.6/userguide/configuration_cache.html

Option configuration-cache doesn't accept value 'true'. Possible values are [OFF, ON, WARN]

Hey folks. Is it possible to have different repositories configured for different environments?

Hey guys, quick question. My Dynamic Modules tests have unresolved reference for Junit. The Dynamic Module build gradle dependencies are just these

dependencies {
    implementation(project(":core"))
    implementation(project(":app"))
}

While my app has

dependencies {
///...
    implementation(project(":core"))
    
    testImplementation(TestLibraryDependency.JUNIT) //neither does this
    addTestDependencies() // this doesn't work
}

But rather I have to explicitly add

testImplementation(TestLibraryDependency.JUNIT)

to my Dynamic Modules build.gradle What is up with that?

Hello everyone! Im doing a native android app with a feature modularization architecture. But my builds are getting slower and slower... Even thought I already enable caching, parallel and the gradle daemon on gradle.propierties... I think it has something to do with dagger implemented in all the feature modules gradle with "api" instead of "implementation". But if I dont use api, then dagger throw compilation error. Does anyone have experienced something like this? Please help!!

Hello, dumb question: I’m on a K-MP project: is it possible to “inject” properties in the compiled code from Gradle? Similarly to what is possible to do on an Android project though

buildConfigField

What’s the difference between

named()

and

getByName()

? Seems to be interchangeable in usage. This is in

NamedDomainObjectCollection.java

how do I do this in Kotlin gradle build file?

apollo {
  customTypeMapping = [
    "type" : "customType"
  ]
}

I'm on a Kotlin Native MPP with Ktor client. Is it possible to switch dependencies automatically by platforms? On Mac requires the client engine for Mac, but on Linux requires it for Linux.

What would be the best way with kotlin script gradle to add the following to every gradle module with the multiplatform plugin applied. I haven't found a way to make the compiler happy using the

subprojects

block. Does anyone have any suggestions?

afterEvaluate {
    kotlin.sourceSets.map {
        it.apply {
            languageSettings.apply {
                useExperimentalAnnotation("kotlin.ExperimentalStdlibApi")
                useExperimentalAnnotation("kotlinx.coroutines.FlowPreview")
                useExperimentalAnnotation("kotlinx.coroutines.ExperimentalCoroutinesApi")
            }
        }
    }
}

Arunkumar helped me get that working, but I can't seem to access the

kotlin

extension, and instead I have. to define it. It's ugly, but works. Anyone know of a solution?

plugins.withType(KotlinMultiplatformPlugin::class) {
        afterEvaluate {
            val kotlin = (this as ExtensionAware).extensions.getByName("kotlin") as org.jetbrains.kotlin.gradle.dsl.KotlinJvmProjectExtension
            kotlin.sourceSets.map {
                it.apply {
                    languageSettings.apply {
                        useExperimentalAnnotation("kotlin.ExperimentalStdlibApi")
                        useExperimentalAnnotation("kotlinx.coroutines.FlowPreview")
                        useExperimentalAnnotation("kotlinx.coroutines.ExperimentalCoroutinesApi")
                    }
                }
            }
        }
    }

Hi, thanks for the excellent support here last time I had a question. This time I have upgraded my Kotlin plugin to 1.4 in IntelliJ IDEA and when I opened build.gradle.kts in one of my projects I got a question "Enable blabla scripting blabla", which I said OK to. Related or not, but almost every line turned red with errors like:

Cannot access 'java.lang.Object' which is a supertype of 'org.gradle.kotlin.dsl.KotlinBuildScript'. Check your module classpath for missing or conflicting dependencies

🤔 Gradle composite builds don't seem to be working as advertised... I'm following the advised pattern of defining a task which 'depends on' another included task e.g.

dependsOn(gradle.includedBuild("someNamedBuild").task(":build"))

...but I get:

Could not determine the dependencies of task ':build'.
> Task with path ':build' not found in project ':someNamedBuild'.

Even though

build

is a task in that included build - I can even see it listed if I instead do:

dependsOn(gradle.includedBuild("someNamedBuild").task(":tasks"))

...which successfully lists the available tasks for

someNamedBuild

, including

build

.

Am I correct in my understanding that because

kotlin-dsl

in buildSrc bundles its own version of Kotlin (which I believe is currently 1.3.72), it is currently impossible to upgrade a Gradle kotlin project to 1.4.0 if we are also authoring plugins using

kotlin-dsl

in buildSrc? We're seeing classpath issues (e.g. NoSuchMethodErrors) relating to still having 1.3.72 on the classpath after upgrading everything to 1.4.0 (we end up with both versions on the classpath). Are we basically stuck on 1.3.72 until Gradle releases a version with a bundled Kotlin 1.4.x?

Hi I have a query

I'm unable to rectify upper bits, where is the register method implemented in gradle I checked for • org.gradle.api.Project • org.gradle.api.Task • org.gradle.api.tasks.TaskProvider But had no luck 😕
