Study Notes

Gradle Overview

Gradle is an automation tool for building and managing projects in languages such as Java, Kotlin, and Scala.
It describes project dependencies and outlines how to build a project effectively.

Plugin System

Features a well-designed plugin system, allowing for extensive customization through plugins which can handle versioning, testing, and reporting.

Build Scripts

Utilizes a Groovy-based domain-specific language (DSL) to allow developers to create custom build scripts.
Kotlin is also supported for writing build scripts, catering specifically to Kotlin developers.

Domain-Specific Language (DSL)

A DSL is tailored for specific application domains, like build automation, unlike general-purpose languages that have broader applications.

Gradle Use Cases

Serves as the de-facto standard for building Android applications, with increasing usage in server-side and desktop development, gradually replacing other tools.

Key Features

Employs settings files to dictate how projects are built and operates on the principle of "build-by-convention," allowing default settings with the option for customization.
Automates dependency management by downloading external libraries and resolving conflicts.
Capable of handling complex builds, including multi-project structures.
Easily adapts to various project structures to fit developers' workflow preferences.
Supports writing scripts using a DSL based on Groovy and Kotlin.

Installation and Verification

Gradle can be downloaded from its official website, with a recommendation to choose version 5.0 or higher.
To verify a successful installation, run the command gradle -v.

Concepts in Gradle

Key concepts include projects (representing buildable entities or tasks) and tasks (jobs executed within a build like compiling or testing).
A Gradle build typically consists of one or more projects, each containing multiple tasks.

Initializing a Project

To initialize a new project, use terminal commands to create a directory (mkdir gradle-demo) and navigate into it (cd gradle-demo).
Running thegradle init command generates a simple project with a basic build structure, prompting the user for parameters through a dialogue in modern versions.

Command Output

After running the Gradle init command, it confirms successful execution with output showcasing actionable tasks and build success status.

Project Structure

A typical project structure includes a build.gradle file alongside a gradle wrapper directory which manages the Gradle version for the project.
