Kotlin·Kotlin from syntax to a coroutine app

Gradle and project structure

Understand the build file, dependencies and modules.

Beginner 13 min read Lesson 9 of 300 Challenge included

What you will be able to do

Keep dependencies in a version catalog.
Use the Kotlin DSL for build files.
Split features into modules when they grow.
Pin plugin versions.

In plain English

Gradle builds Kotlin projects and Android apps. The version catalog centralises dependency versions. Keep modules focused so build times and responsibilities stay small.

build.gradle.ktsKotlin

plugins {
    kotlin("jvm") version "2.1.0"
    application
}

dependencies {
    implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.10.1")
}

application {
    mainClass.set("MainKt")
}

Your turn
