Initialization

Gradle Initialization Phase: Overview and Key Details

The Initialization phase is the first and foundational step in the Gradle build lifecycle. Its primary role is to determine which projects are involved in the build and to prepare the environment for configuration and execution.

Key Responsibilities of the Initialization Phase:

Project Identification:

Gradle detects all projects involved in the build.
For single-project builds, only the main project is initialized.
For multi-project builds, Gradle evaluates the settings.gradle.kts to include subprojects.

Example:
```
// settings.gradle.kts
rootProject.name = "my-multi-project"
include("app", "lib")
```

Settings File Evaluation:

The settings.gradle.kts file defines the structure of the project and which subprojects are included in multi-project builds.
Gradle uses this file to establish the hierarchy and relationships between projects.

Environment Setup:

Gradle sets up the build environment, which includes reading configuration files such as gradle.properties, initializing system properties, and setting JVM arguments.
It also configures logging and prepares the plugin repositories for the build process.

Purpose of the Initialization Phase:

The Initialization phase ensures that Gradle knows what will be built by determining the projects and preparing the environment for further phases.
It serves as the foundation for the Configuration and Execution phases by making sure all projects and settings are ready.

By handling project detection and environment setup, the Initialization phase sets up the context for the rest of the build lifecycle in Gradle, ensuring smooth configuration and execution later.
