Unresolved reference: AntlrKotlinTask with gradle 9.0

[bingo-soft]

I could not find any working build.gradle.kts, so I just tried this:

plugins {
    kotlin("jvm") version "2.0.21"
    id("com.vanniktech.maven.publish") version "0.28.0"
    id("antlr")
    id("com.strumenta.antlr-kotlin") version "1.0.0"
}

group = "com.example"
version = "unspecified"

repositories {
    mavenCentral()
}

dependencies {
    antlr("org.antlr:antlr4:4.13.2")
    implementation("com.strumenta:antlr-kotlin-runtime:1.0.0")
}

val generateGrammarSource by tasks.registering(AntlrKotlinTask::class) {
    //...
}

And that gives me an error:

val generateGrammarSource by tasks.registering(AntlrKotlinTask::class) {
                                                          ^ Unresolved reference: AntlrKotlinTask

Do not know how to fix it. Thanks in advance!

I also tried this gradle.build.kts - https://github.com/Strumenta/antlr-kotlin/blob/master/antlr-kotlin-tests/build.gradle.kts. And that gives an errors as well:

Line 10:     alias(libs.plugins.kotlinx.resources)
                     ^ Unresolved reference: libs

It would be really great to have some fresh hello-world example that we could use a starting point. Probably, there is one, but I could not find it. Many thanks for any advice!

Hey! Could you publish a small reproducer that we can clone and check out?

Heads up tho, you should not include both the built-in antlr plugin and the Strumenta one.
You should also specify the platform in your dependency declaration since you're creating a jvm-only project.

implementation("com.strumenta:antlr-kotlin-runtime-jvm:1.0.2")

I managed to make it work. Like so:

plugins {
    kotlin("jvm") version "2.0.21"
    id("antlr")
    id("com.strumenta.antlr-kotlin") version "1.0.0"
}

group = "com.example"
version = "1.0.2"

repositories {
    mavenCentral()
}

dependencies {
    antlr("org.antlr:antlr4:4.13.2")
    implementation("com.strumenta:antlr-kotlin-runtime:1.0.0")
    testImplementation(kotlin("test"))
}

sourceSets["main"].java.srcDir("build/generated-src/antlr/main")

tasks.register<com.strumenta.antlrkotlin.gradle.AntlrKotlinTask>("generateKotlinGrammarSource") {
    maxHeapSize = "64m"
    packageName = "com.example.antlr"
    arguments = listOf("-visitor")
    source = project.objects
        .sourceDirectorySet("antlr", "antlr")
        .srcDir("src/main/antlr").apply {
            include("*.g4")
        }
    //outputDirectory = File("src/build/generated-src")
}

tasks.named("generateGrammarSource").configure {
    enabled = false
}

tasks.named("compileKotlin") {
    dependsOn(tasks.named("generateKotlinGrammarSource"))
}

Thanks for the update.

I'll try to add a JVM-only setup section to the readme so that it's easier to understand how to do it.
