kotlinlang #gradle

Duplicate class org.apache.http.Consts found in modules jetified-httpclient-android-4.3.5 (org.apache.httpcomponents:httpclient-android:4.3.5) and jetified-httpcore-4.3 (org.apache.httpcomponents:httpcore:4.3.3)

The best guess I have currently is that something is duplicated or incorrect in the build.gradle file.

I am trying to convert groovy tasks from a previous project to my new project that now is a

.kts

gradle file and I dont know how to convert them properly here are my two tasks

task androidJavadocs(type: Javadoc) {
    failOnError = false
    source = android.sourceSets.main.java.srcDirs
    ext.androidJar = "${android.sdkDirectory}/platforms/${android.compileSdkVersion}/android.jar"
    classpath += files(ext.androidJar)
    exclude '**/R.html', '**/R.*.html', '**/index.html'
}

task androidJavadocsJar(type: Jar, dependsOn: androidJavadocs) {
    classifier = 'javadoc'
    from androidJavadocs.destinationDir
}

Can anyone help me out with this?

I’m trying to use a library via

includeBuild("../nanotest")

and

testImplementation("nanotest:nanotest:0.1")

the build file of the library has this:

group = "nanotest"
version = "0.1"

and the settings file this:

rootProject.name = "nanotest"

but when i build gradle does not find it:

Could not resolve nanotest:nanotest:0.1.
Required by:
    project :

I use composite builds all the time and it just works but now i have no idea whats wrong

Is it possible to have a custom Gradle task that exposes a function as part of the API?

i’m migrating from groovy to kotlin and i have a question about extensions. I would like to create an extension in a kotlin file under

buildSrc

and access that extension from all the gradle scripts in my project. I was under the impression that it was possible since all files under

buildSrc

are automatically added to the class path but it doesn’t seem to work for me. When i define the extension in the same class as its usage, it works fine

build.gradle.kts

repositories {
    myExtension()
}

fun RepositoryHandler.myExtension(): MavenArtifactRepository =
maven {
    // Some code
}

But if i define the extension in another file, i can’t seem to get it to work as here:

build.gradle.kts

import extensions.myExtension

repositories {
    myExtension()
}

buildSrc/src/main/kotlin/extensions/MyExtensionFile.kt

package extensions
// some imports

fun RepositoryHandler.myExtension(): MavenArtifactRepository =
maven {
    // Some code
}

Specifying the extension in another file yields -

Unresolved reference: extensions

.Is it possible to have such a setup with reusable extensions accessible from all the gradle files?

So, we have an app that’s comprised of mutliple smaller libraries. Our dev team is pretty big, so we work in our individual libraries until a feature is ready and then it gets integrated into the app. We’re starting now to use a maven BOM file (which i generate with a custom build.gradle script and publish to nexus). This helps with the jar hell in terms of managing the versions of jetpack libraries that are being used. However, i haven’t really found a way to make sure we’re all on the same gradle plugin and kotlin plugin version. I tried using something like this in the buildscirpt block but it doesn’t work:

classpath(platform(...))
classpath("com.android.tools.build:gradle")

Could somebody help converting plugins syntax back to apply plugin? I'm not on the new stuff yet

plugins {
    id("symbol-processing") version "1.4.20-dev-experimental-20201222"
}

I searched maven for "symbol-processing" as to give me the full path, but no luck -- where is that plugin hosted if nothing else is specified?

My gradle sync times (android studio) are getting quite annoyingly long, so I wanted to implement lazy tasks (as I have bunch of static analysis, test setup). First, I naivelly tried to delete those tasks, to see what would be the best case scenario -- and turns out, it did almost nothing Only thing that seems to improve sync times, is simply to not sync everything I have a monorepo setup, a single gradle project with 3 application modules (3 apps) and many shared code modules Most of the time one only works on a single app, so its not necessary to have the other app's modules loaded (and CI will check for breaks everywhere anyway) Is there something more sophisticated other than commenting out modules from
settings.gradle
? (I noticed the

Load/Unload Modules...

intellij option, which does exactly that, but for builds (green hammer icon), and sync times stay the same, even with the other apps modules unloaded -- so a no go)

    apply(plugin = "io.gitlab.arturbosch.detekt")
    apply(plugin = "org.jlleitschuh.gradle.ktlint")

    dependencies {
        detektPlugins("io.gitlab.arturbosch.detekt:detekt-formatting:1.14.2")
    }

    // Configure detekt plugin.
    // Read more: <https://detekt.github.io/detekt/kotlindsl.html>
    detekt {
        config = files("${rootProject.projectDir}/detekt-config.yml")
        buildUponDefaultConfig = true

        reports {
            html.enabled = false
            xml.enabled = false
            txt.enabled = false

    tasks {
        withType<Detekt> {

I'm using IntelliJ 2020.3 and Gradle 6.8-rc-1. Does anyone have any tips for speeding up auto-complete and IntelliJ analysis of the gradle files, it seems to take like 5 seconds for auto complete to show up, etc... I have seen this is partially a known issue in the past: https://blog.jetbrains.com/kotlin/2020/02/improved-gradle-kts-ide-support/

does gradle have its own slack workspace or other venue for asking non-kotlin specific gradle questions?

question about kotlin-dsl, seems like it behaves differently than groovy:

subprojects {
   repositories {
        mavenCentral()
        jcenter()
    }
}

Dependency is only available in jcenter but the build fails telling me that the dependency is not available in mavenCentral. How can I declare two repositories? (https://docs.gradle.org/current/userguide/declaring_repositories.html#sec:declaring_multiple_repositories looks like it should be correct)

Hey folks. I'm trying to upgrade a dependency defined as

api 'tech.relaycorp:relaynet:[1.40.0,2.0.0)'

, and I want to require

1.41.0

at a minimum. However, I keep getting the following error:

Execution failed for task ':compileKotlin'.
> Could not resolve all files for configuration ':compileClasspath'.
   > Could not find any version that matches tech.relaycorp:relaynet:[1.41.0,2.0.0).
     Versions that do not match:
       - 1.40.0
       - 1.39.1
       - 1.39.0
       - 1.38.4
       - 1.38.3
       - + 76 more
     Searched in the following locations:
       - <https://jcenter.bintray.com/tech/relaycorp/relaynet/maven-metadata.xml>

However, if you download that

maven-metadata.xml

file you'll find version

1.41.0

. I get that on CI (https://github.com/relaycorp/relaynet-jvm-testing/pull/21/files) and my local computer. If I use

api 'tech.relaycorp:relaynet:1.41.0

gradle build

works, but I can't use a fixed version here. Any thoughts on how to fix this?

Hi! I am porting a Groovy based

android

is not a property of

project

)

janvladimirmostert

01/09/2021, 11:08 AM

in a root

build.gradle.kts

you can set the version for all plugins:

plugins {

	val kotlinVersion = "1.4.21"
	val shadowVersion = "6.0.0"

	kotlin("multiplatform").version(kotlinVersion).apply(false)
	kotlin("plugin.serialization").version(kotlinVersion).apply(false)
	id("com.github.johnrengelman.shadow").version(shadowVersion).apply(false)

}

is there a way to do it with dependencies as well? I've tried adding a dependency block with a

constraint{...}

, but the IDE doesn't allow me to add an

implementation(...)

inside such a constraint block

Hello 👋 Anyone else is hitting a problem that Gradle 6.8 cannot resolve platform specific Kotlin module? Trying to bump up Ktor dependencies to 1.5 (from 1.3.1) (https://github.com/ExpediaGroup/graphql-kotlin/pull/1007) What is odd is that if I wipe out my Maven

.m2/repository

it works initially but then it subsequently fails (i.e. only sees

ktor-client-cio

which fails the build as it needs

ktor-client-cio-jvm

). Chain of events (from the linked PR GH build action): • manually wipe out

.m2/repository

and start a build • project A and B are build fine and are able to resolve the

-jvm

artifacts • integration tests kick in for maven and gradle plugins - maven tests work fine - gradle tests (using GradleRunner) fail to resolve

-jvm

artifacts • project A and B cannot be build anymore and are unable to resolve the

-jvm

artifacts Locally • wipe out the

.m2/repository

• build project A or B from command line using Gradle wrapper - works fine • reload project in IDEA (which uses Gradle wrapper) -> cannot resolve the

-jvm

artifacts

I have a question (I'm using Kotlin Gradle plugin 1.4.21): If my only dependency is

testImplementation 'org.jetbrains.kotlin:kotlin-test-junit'

, it seems that I don't have to specify a version! Why? I don't have the Kotlin BOM specified either. Only the

kotlin-test

dep. And of course the Kotlin Gradle plugin. I know that this version automatically provides the

kotlin-stdlib

version including the variant (e.g. JDK8), but judging by this behaviour, it also seems that it provides some kind of Kotlin BOM platform (or at least version constraints) for the

kotlin-test

dep (and who knows what others). How does this work? And is it ok to rely on the Kotlin Gradle Plugin version for the

kotlin-test

dependency?

how does one include a library from another project of which you have the code checked out? ProjectB's settings.gradle.kts:

include("project-a:module-4")

project(":project-a:module-4").projectDir =
    File("../project-a/module-4")

ProjectB Module4's build.gradle.kts

sourceSets {
                       val jvmMain by getting {
                           dependencies {
                               ...
                               implementation(project(":project-a:module-4"))


                           }
                       }
                   }

this compiles, but nothing resolves

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileKotlin'.
> Internal compiler error. See log for more details

The fix is to add

--add-opens java.base/java.util=ALL-UNNAMED

option when running java. I tried to set this option in all the following places like 1. gradle properties

org.gradle.jvmargs=

export JAVA_OPTS="--add-opens java.base/java.util=ALL-UNNAMED"

3. java compile task

compilerArgs.addAll(
                listOf(
                    "--enable-preview",
                    "--add-opens",
                    "java.base/java.util=ALL-UNNAMED"

4. Kotlin compile task

freeCompilerArgs += listOf(
                "-progressive",
                "-Xjavac-arguments=" + listOf(
                    "--add-opens",
                    "java.base/java.util=ALL-UNNAMED"
                ).joinToString(separator = ",")

None of these options worked and still getting the above error. Any hint on how to open JDK modules to my all application packages?

Vampire

01/18/2021, 8:37 AM

1. Are args for running Gradle itself 2. Is also just looked at by start scripts like the wrapper 3. Is for compiling java, that can never help for compiling Kotlin 4. Sounds reasonable except that you give

--add-opens,java.base/java.util=ALL-UNNAMED

, this is most likely not correct. I wonder that it did not complain about that syntax

io.ktor:ktor-client-cio-jvm

to be picked up on JVM builds)?

I would avoid the kotest gradle plugin as that is experimental, and use the kotest/junit integration which you have added via the kotest-framework-engine-jvm dependeny.

LevT

01/23/2021, 7:07 AM

There is an official word in the docs that seems claiming the opposite "This is an alternative to using JUnit5 support and provides better output than the gradle default, especially for nested tests." https://github.com/kotest/kotest-gradle-plugin BTW, I need a kind of multitest build as a learning device, to get some fluency refactoring tests (between test frameworks) and to select the best framework up to my needs

If I disable the kotest-framework-engine-jvm dependency there is no more FunSpec еtс. What to be added instead?

Sorry I'm getting opposite advice right now, but still have no understanding how to manage builds, these ones that include kotest
