Forma - Kotlin first, Meta Build System with Android and Gradle support. Opinionated, scalable, thoughtfully structured, type-safe and guided way to declare your project structure. Distributed as a Gradle plugin, Forma helps developers to shift focus from Build Configuration to Project Structure Declaration, abstracting away build configuration complexity.

• You don't need to be a gradle expert anymore
• Get rid of project configuration bad practices
• Type-safe, single method configuration for your targets, no room for error
• Built-in dependency visibility rules
• Target types - enforce scalable project structure
• High-performance builds: Gradle best practices are applied automatically
• Dependencies framework - helps developers to understand and deal with transitive dependencies hell
• Extensible - be the expert when you need to!
• And much more...

⚠️ We are using target term to express application components(e.g. modules or projects, depending on the context) across documentation and code, there is a couple of reasons for that. Module term often confused with Dagger modules which makes communication harder, project from the other hand used only in Gradle context but not in other build systems like Buck and Bazel.

⚠️ This is still under development. We will notify you when it will be ready for first users For now you can check concept from original repo creator Presentation Link

How to use

Configuration made easy (Gradle 6.8+):

1. Set repositories in settings.gradle(.kts) to download plugin

  dependencyResolutionManagement {
      @Suppress("UnstableApiUsage")
      repositories {
          google()
          jcenter()
      }
  }
  

2. Apply plugin in your root build.gradle(.kts)

  // 
  buildscript {
      repositories {
          google()
      }
  }
  
  plugins {
      id("ru.tinkoff.forma.android") version "0.1.0"
  }
  
  // Configure shared aspects of your android Project
  androidProjectConfiguration(
      minSdk = 21,
      targetSdk = 31,
      compileSdk = 33,
      kotlinVersion = "1.8.10",
      agpVersion = "7.4.2",
      versionCode = 1,
      versionName = "1.0"
  )

3. Setup your kotlin android module with forma dsl

   // Single method, type-safe creation of your target
   // Plugins applied automatically
   // Project configuration shared between targets
   androidLibrary(
       // Mandatory, visible from build configuration
       packageName = "com.stepango.example",
       // External dependencies declaration, one universal syntax
       dependencies = deps(
           google.material,
           androidx.appcompat,
       ) + deps(
           // Internal project dependencies, declared separately from externals
           target(":demo-library")
       ),
       // Test dependencies declaration
       testDependencies = deps(
           test.junit
       ),
       // Android test dependencies declaration
       androidTestDependencies = deps(
           test.espresso
       )
   )
