Gradle build scripts are a powerful way to define the build logic for your project. This guide will help you get started with writing your own build scripts.

Introduction

A build script is a set of instructions that Gradle uses to build your project. It defines the tasks that need to be executed, the dependencies that are required, and the configurations that are applied.

Basic Structure

A typical build script has the following structure:

plugins {
    id 'java'
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'com.google.guava:guava:30.1-jre'
}

tasks {
    jar {
        from sourceSets.main.output
    }
}

Plugins

The plugins block is used to apply plugins to your project. In the example above, the Java plugin is applied, which adds support for Java projects.

Repositories

The repositories block is used to specify the repositories from which Gradle should download dependencies.

Dependencies

The dependencies block is used to declare the dependencies that are required by your project.

Tasks

The tasks block is used to define the tasks that are part of your project. In the example above, a jar task is defined, which creates a JAR file from the main source set.

Advanced Topics

Gradle build scripts are highly customizable. You can define custom tasks, extend existing tasks, and even write custom Gradle plugins.
