java {
    sourceCompatibility = JavaVersion.VERSION_11

    compileOnly("org.apache.spark:spark-sql_2.12:3.2.1")

tasks {
    build {
        dependsOn(shadowJar)
    }
}

tasks{
    named<ShadowJar>("shadowJar"){
        dependencies {
            exclude {
                it.moduleGroup == "org.apache.spark" || it.moduleGroup == "org.scala-lang"
            }
        }
    }
}

fixed by change compileOnly to implementation the documentation should update 😂

dependencies {
    implementation(kotlin("stdlib"))
    implementation("org.jetbrains.kotlinx.spark:kotlin-spark-api-3.2:1.0.3")
    implementation("org.apache.spark:spark-sql_2.12:3.2.0")
}
