kotlinlang #gradle

I can't figure out how to do this in kotlin. reobfJar is a task. I want the reobfJar task to also be run on the shadowJar too. (not sure quite how this works unfortunately) The closest i've got i think is:

tasks.all {
    println("Task $this, path ${this.path}")
    if (this.path == ":reobfJar") {
        println("I AM REOBFJAR!")
        this.configure<net.minecraftforge.gradle.patcher.tasks.ReobfuscateJar> {
            tasks.getByName("shadowJar")
        }
    }
}

I can't figure out how to get the reobfjar task without iterating, .getByPath doesn't seem to work. But also this.configure seems to want an Extension instead of a task? No clue what im supposed to do here.

Hey guys, how to declare a function inside project build.gradle and use it inside app build gradle, it was possible with Groovy

I don't know why I keep on getting mysterious errors in gradle like this:

e: .../app/build.gradle.kts:10:45: Unresolved reference: util
e: .../app/build.gradle.kts:11:65: Unresolved reference: newDataInputStream

I updated to gradle 7.3.3 and android plugin 7.0.4...

It seems like AndroidStudio's import suggestions don't work too well with gradle kts... and inlining the import doesn't work either...

I want to create a kotlin only library module in my android app. I went through and created it using the wizard and got this

plugins {
    id("java-library")
    id("org.jetbrains.kotlin.jvm")
}

but then I went and looked at an old project and it had a kotlin only lib module that looked like this:

plugins {
    id("java-library")
    id("kotlin")
}

So is there any diff between the second lines in both of these?

using

kotlin-multiplatform

plugin, is it possible to create a sourceSet from a folder that’s sibling to the module that I’m currently configuring? As in, I have modules A and B, like so:

moduleA
  test
  testShared
  build.gradle.kts
moduleB
  test
  build.gradle.kts

I would like to include

testShared

when running

:moduleB:test

What I have on moduleA:

val jvmTestShared by creating
    val jvmTest by getting {
      dependencies {
        dependsOn(jvmTestShared)
      }
    }

but I can’t seem to be able to create

jvmTestShared

on moduleB

leandro

01/17/2022, 6:25 PM

Yes, I can move

testShared

anywhere, actually. It’s quite a unique setup because I can only run it on JVM targets, so even having one depending on the other might be tricky because ArchUnit does not know about

kotlin-multiplatform

plugin

hi! Sorry if this is a Groovy question but this is blocking me from migrating to Kotlin DSL. I'm trying to figure out how to call the

create()

function here from a Groovy gradle file. I've tried calling this way:

cklib {
    create("sqlighter") {
        language "co.touchlab.cklib.gradle.CompileToBitcode.Language.OBJC"
    }
}

but I'm getting:

org.gradle.api.GradleScriptException: A problem occurred evaluating project ':SharedCode'.
...
Caused by: groovy.lang.MissingMethodException: No signature of method: build_89t0gtdiazmlot5b0npjl25b8.cklib() is applicable for argument types: (build_89t0gtdiazmlot5b0npjl25b8$_run_closure3) values: [build_89t0gtdiazmlot5b0npjl25b8$_run_closure3@7e7932ea]
Possible solutions: mkdir(java.lang.Object), split(groovy.lang.Closure), wait(), file(java.lang.Object), wait(long), copy(groovy.lang.Closure)

Here's a working example of it being called from Kotlin DSL. What simple syntax error am I making? 🙂

I have a code in lagacy style:

buildscript {
    repositories {
        maven {
            url = uri("<https://files.minecraftforge.net/maven>")
        }
        mavenCentral()
    }
    dependencies {
        classpath("net.minecraftforge.gradle", "ForgeGradle", "5.+") {
            isChanging = true
        }
    }
}

How can I rewrite it into apply(plugin="smth") style? This does not work:

repositories {
   maven(url = "<https://maven.minecraftforge.net>")
   mavenCentral()
}

apply(plugin = "net.minecraftforge.gradle:ForgeGradle:5.+")

what is the best way to add git submodule sources to project? I want to submodule use own

build.gradle(kts)

files, but if i add it as

project

dependency (

:path:to:submodule

) submodule use root project

build.gradle(kts)

files to build its sources and i must to synschronize build variables. It is kind of easy (but not normal) if i use own project as submodule, but what if i want to add any project and it has own gradle build architecture?

Is it possible to apply specific Kotlin compiler arguments for an Android build variant ? I can configure arguments with

tasks.withType<KotlinCompile>().configureEach {
  kotlinOptions {
    freeCompilerArgs = freeCompilerArgs + listOf(
      "-Xno-param-assertions",
      "-Xno-call-assertions",
      "-Xno-receiver-assertions"
    )
  }
}

but it's applied to all build variants, which is not what I want. The

kotlin.android

Gradle plugin creates compilation tasks (

compileDebugKotlin

compileReleaseUnitTestKotlin

, etc) for each source set, but it seems there is no way to configure their

kotlinOptions

individually.

Hi everyone, I have a project with a few dependencies (kafka, spring etc) and I'm trying to create a jar file for kafka connect with only my kafka connect relevant code and a single dependency. Since I'm already using shadow, I've tried to create the task like thi

// Custom jars for kafka connect
create<ShadowJar>("kafkaConnectUtilsJar") {
    archiveClassifier.set("connect-utils")
    include("co/visup/kafkaProcessor/connect/**")
    include("co/visup/kafkaProcessor/serializer/**")
    dependencies {
        include(dependency("io.confluent:kafka-connect-storage-partitioner:10.2.4"))
    }
    from(project.sourceSets.main.get().output)
    configurations = listOf(project.configurations.runtimeClasspath.get())
}

however while I see the classes in

co/visup

etc, I don't see the dependency, anyone has any idea?

Hey all, I’m wondering if anyone has any learning resources they can share for Gradle? I’ve been programming Android apps for around 8 years now and still find Gradle to be one of the most challenging parts of my job and the area where I seem to waste a large amount of time. I think part of it is just not understanding the full extent of the tool. So if anyone has any books, blogs, video resources on the topic that helped them understand Gradle better I’d really appreciate it. 🙂

Using the latest Gradle and .kts build scripts, how can I specify compiler options for a custom sourceSet? For example, for main and test sourceSets it's:

tasks {
    compileKotlin {
        kotlinOptions { ... }
    }
    compileTestKotlin {
        kotlinOptions {... }
    }
}

How would I specify options for some other buildSrc, let's call it "someOtherSrc"?

I want to tweak JVM parameters for testing - is there a difference between

tasks { test { jvmArgs = ...}}

vs.

tasks { withType<Test> { jvmArgs = ...}

? It seems to work identically, but is one way better than the other?

Hi, I'm trying to automatically add compiler opt-ins for all my modules (where it matters). But the "where it matters" is important, otherwise when the opt-in annotation is not available the build fails (as we utilize warning as errors). Zac's workaround is nice, but doesn't account for transitive dependency.

configurations
    .configureEach {
      incoming.afterResolve {
        dependencies.forEach { dependency ->
          if (dependency.name == "eithernet") {
            tasks.withType<org.jetbrains.kotlin.gradle.tasks.KotlinCompile>().configureEach {
              kotlinOptions {
                @Suppress("SuspiciousCollectionReassignment")
                freeCompilerArgs += "-Xopt-in=com.slack.eithernet.ExperimentalEitherNetApi"
              }
            }
          }
        }
      }
    }

I've spent two days resolving the transitive deps but still failing to do it properly anyhow. Any idea?

How does

val answer: String by project

work?

Project

interface doesn’t have

getValue()

and

setValue()

, so how does it work as a delegate then?

Does it make sense to see more than 2

java

processes running? I presume 1 is for kotlin deamon, 2nd is for gradle daemon. But are 3, 4 necessary? They both seem to be pointing to gradle. Is this normal or possible a bug? (Since there are issues with new AS version not respecting the JDK path settings and using its own packages JRE etc; and no I’m not couting these in)

Hi, has anyone ran into trouble with gradle task

:kaptGenerateStubsKotlin

with

java.lang.NoClassDefFoundError: Could not initialize class <http://org.jetbrains.kotlin.com|org.jetbrains.kotlin.com>.intellij.pom.java.LanguageLevel

on JVM 17? I’m having a “it works on my machine” problem and the only difference seems to be the JVM version. We were able to amend it by adding gradle.properties settings option

org.gradle.jvmargs=-Dkotlin.daemon.jvm.options=--illegal-access=permit

, but it seems like out of random the build fails even with the option too, in which case we remove the option again-- as if the error switches on and off out of nowhere. Any hints would be appreciated! Thanks in advance!

I'm trying to split my build.gradle.kts into multiple files, but while the gradle script does run when split and using

apply(from="/path/to/file.gradle.kts")

, I don't seem to get any syntax highlighting or other IDA features. Is there a different way I should split gradle scripts?

Weird Gradle behaviour regarding

inline

: I'm moving code out of my

build.gradle.kts

into extension functions on Android's

LibraryExtension

buildSrc

, making the config nice and neat 👍 After moving the code, it doesn't work 😱, Gradle behaves as though the config hasn't applied, even though the calls are there and it compiles. One of the things I tried out of desperation was to make the functions

inline

, and suddenly it all works!!! Never before have I come across a situation in Kotlin where

inline

changes behaviour 🤷 Oh Gradle... the tool that's guaranteed to keep me humble as a developer. Whenever I think I've finally understood it; you can be guaranteed a heavy fall is just around the corner.

That's then maybe more a bug somewhere? Can you reproduce that behavior in an MCVE? Sounds pretty strange.
