An example for a build.gradle.kts file of a project using KSpigot would be:

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

plugins {
    kotlin("jvm") version "1.5.21"
}

group = "your.group"
version = "1.0-SNAPSHOT"

repositories {
    mavenCentral()
    maven("https://hub.spigotmc.org/nexus/content/repositories/snapshots")
}

dependencies {
    compileOnly("org.spigotmc:spigot-api:1.17-R0.1-SNAPSHOT")
    implementation("net.axay:kspigot:1.17.2")
}

tasks {
    compileJava {
        options.release.set(16)
        options.encoding = "UTF-8"
    }
    compileKotlin {
        kotlinOptions.jvmTarget = "16"
    }
}
