`GraalVM`'s native-image is unable to find my lib specified in my build.gradle.kts file:

plugins {
    kotlin("jvm") version "1.9.23"
}

group = "com.example"
version = "1.0-SNAPSHOT"

tasks.withType<Jar> {
    manifest {
        attributes["Main-Class"] = "com.example.SampleCli"
    }
}

repositories {
    mavenCentral()
}

dependencies {
    implementation("com.github.ajalt.clikt:clikt:4.3.0")
    testImplementation(kotlin("test"))
}

tasks.test {
    useJUnitPlatform()
}

kotlin {
    jvmToolchain(21)
}

task<Exec>("buildNativeImage") {
    description = "Build native image using GraalVM"
    dependsOn(tasks.getByName("build"))
    workingDir(buildDir)
    commandLine(
        "native-image",
        "-cp", getClasspath(),
        "-H:+ReportExceptionStackTraces",
        "-H:+AddAllCharsets",
        // "--report-unsupported-elements-at-runtime",
        // "--allow-incomplete-classpath",
        "--no-server",
        "--no-fallback",
        "--enable-http",
        "--enable-https",
        "com.example.SampleCli",
        "com.example"
    )
}

Whereas I can build it using ./gradlew build, GraalVM can't find my dependency when I try to run the task:

/gradlew buildNativeImage

or even when I try to run native-image manually:

native-image -jar build/libs/SampleCli-1.0-SNAPSHOT.jar cli

Error (same error for both actions):

========================================================================================================================
GraalVM Native Image: Generating 'cli' (executable)...

The build process encountered an unexpected error:

Am able to run this main class fine via IntelliJ...

build/libs/SampleCli-1.0-SNAPSHOT.jar only contains your code, not dependencies.

Have you checked if there is a GraalVM plugin that exists?

If not, add an according -cp ... argument to the native-image call, so that also the dependencies are built into the result

But there is: https://graalvm.github.io/native-build-tools/latest/gradle-plugin.html
