Maven

Maven is a build system that helps manage Kotlin-only or mixed Kotlin−Java projects and automate your building process. It works with JVM-based projects and downloads required dependencies, compiles and packages your code. Learn more about its basics and specifics on the Maven website.

Here's a general workflow when working with a Kotlin Maven project:

Apply the Kotlin Maven plugin.
Declare repositories.
Set project dependencies.
Configure source code compilation.
Configure the Kotlin compiler.
Package your application.
