Project configuration with Amper

Amper is a new tool created by JetBrains to help you configure projects for building, packaging, publishing, and more. With Amper, you can spend less time dealing with build systems and focus on addressing real business challenges instead.

Amper lets you create configuration files for Kotlin Multiplatform applications that work on the JVM, Android, iOS, macOS, Windows, and Linux, as well as for multiplatform libraries that work with all of these supported targets.

How Amper works

Amper is a standalone CLI application, and allows configuring your project using YAML files.

With Amper, you can set up a platform-specific applications and shared Kotlin libraries. They are declared as modules in a module.yaml manifest file using a special declarative DSL.

The core concept of this DSL is Kotlin Multiplatform. Amper allows you to configure Kotlin Multiplatform projects quickly and easily without having to dive deep into complex concepts. The Amper DSL offers a special syntax enabling you to work with multiplatform configurations, including dependencies, settings, and so on.

Here is an example of Amper's module file for a Kotlin Multiplatform shared library that can be used with JVM, Android, and iOS applications:

product:
  type: lib
  platforms: [ jvm, android, iosArm64, iosSimulatorArm64, iosX64 ]

# Shared Compose Multiplatform dependencies:
dependencies:
  - org.jetbrains.compose.foundation:foundation:1.5.0-rc01: exported
  - org.jetbrains.compose.material3:material3:1.5.0-rc01: exported

# Android-only dependencies  
dependencies@android:
  # Integration compose with activities
  - androidx.activity:activity-compose:1.7.2: exported
  - androidx.appcompat:appcompat:1.6.1: exported

settings:
  # Enable Kotlin serialization
  kotlin:
    serialization: json

  # Enable Compose Multiplatform framework
  compose: enabled

The product section defines the project type and the list of targeted platforms.
The dependencies section adds Maven dependencies, and in the future may support platform-specific package managers, such as CocoaPods and Swift Package Manager.
The @platform qualifier marks platform-specific sections, including dependencies and settings.
