# Gradle Build Language Reference

### Version 9.2.0-branch-sigushkinDeclarativeComposability-20250818215312+0000

## Introduction

This reference guide describes the various types which make up the Gradle build language, or DSL.

## Some basics

There are a few basic concepts that you should understand, which will help you write Gradle scripts.

First, Gradle scripts are configuration scripts. As the script executes, it configures an object of a particular type. For example, as a build script executes, it configures an object of type `Project`. This object is called the delegate object of the script. The following table shows the delegate for each type of Gradle script.

Type of script | Delegates to instance of
Build script | `Project`
Init script | `Gradle`
Settings script | `Settings`

The properties and methods of the delegate object are available for you to use in the script.

Second, each Gradle script implements the `Script` interface. This interface defines a number of properties and methods which you can use in the script.

## Build script structure

A build script is made up of zero or more statements and script blocks. Statements can include method calls, property assignments, and local variable definitions. A script block is a method call which takes a closure as a parameter. The closure is treated as a configuration closure which configures some delegate object as it executes. The top level script blocks are listed below.

Block | Description
`allprojects { }` | Configures this project and each of its sub-projects.
`artifacts { }` | Configures the published artifacts for this project.
`buildscript { }` | Configures the build script classpath for this project.
`configurations { }` | Configures the dependency configurations for this project.
`dependencies { }` | Configures the dependencies for this project.
`repositories { }` | Configures the repositories for this project.
`subprojects { }` | Configures the sub-projects of this project.
`publishing { }` | Configures the `PublishingExtension` added by the publishing plugin.

A build script is also a Groovy script, and so can contain those elements allowed in a Groovy script, such as method definitions and class definitions.

## Core types

Listed below are some of the central types which are used in Gradle scripts:

Type | Description
`Project` | This interface is the main API you use to interact with Gradle from your build file. From a `Project`, you have programmatic access to all of Gradle's features.
`Task` | A `Task` represents a single atomic piece of work for a build, such as compiling classes or generating javadoc.
`Gradle` | Represents an invocation of Gradle.
`Settings` | Declares the configuration required to instantiate and configure the hierarchy of `Project` instances which are to participate in a build.
`IncludedBuild` | A build that is included in the composite.
`ProjectLayout` | Provides access to several important locations for a project.
`BuildLayout` | Provides access to important locations for a Gradle build.
`Script` | This interface is implemented by all Gradle Groovy DSL scripts to add in some Gradle-specific methods. As your compiled script class will implement this interface, you can use the methods and properties declared by this interface directly in your script.
`SourceSet` | A `SourceSet` represents a logical group of Java source and resource files. They are covered in more detail in the user manual.
`SourceSetOutput` | A collection of all output directories (compiled classes, processed resources, etc.) - notice that `SourceSetOutput` extends `FileCollection`.
`SourceDirectorySet` | A `SourceDirectorySet` represents a set of source files composed from a set of source directories, along with associated include and exclude patterns.
`Configuration` | A `Configuration` represents a group of artifacts and their dependencies. Find more information about declaring dependencies to a configuration or about managing configurations in docs for `ConfigurationContainer`
`ConsumableConfiguration` | A `Configuration` which can be consumed via Publishing and Dependency Management.
`ResolvableConfiguration` | A `Configuration` which performs dependency resolution to build dependency graphs and resolve artifacts.
`DependencyScopeConfiguration` | A `Configuration` which collects dependencies, dependency constraints, and exclude rules.
`ResolutionStrategy` | Defines the strategies around dependency resolution. For example, forcing certain dependency versions, substitutions, conflict resolutions or snapshot timeouts.
`ArtifactResolutionQuery` | A builder to construct a query that can resolve selected software artifacts of the specified components.
`ComponentSelection` | Represents a tuple of the component selector of a module and a candidate version to be evaluated in a component selection rule.
`ComponentSelectionRules` | Represents a container for component selection rules. Rules can be applied as part of the resolutionStrategy of a configuration and individual components can be explicitly accepted or rejected by rule. Components that are neither accepted or rejected will be subject to the default version matching strategies.
`DependencyCollector` | A `DependencyCollector` is used as part of a dependencies block in the DSL. A collector implements a single dependency scope and exposes the declared dependencies on `DependencyCollector.getDependencies()`.
`ExtensionAware` | Objects that can be extended at runtime with other objects.
`ExtraPropertiesExtension` | Additional, ad-hoc, properties for Gradle domain objects.
`PluginDependenciesSpec` | The DSL for declaring plugins to use in a script.
`PluginDependencySpec` | A mutable specification of a dependency on a plugin.
`PluginManagementSpec` | Configures how plugins are resolved.
`ProviderFactory` | A factory for creating instances of `Provider`.
`ResourceHandler` | Provides access to resource-specific utility methods, for example factory methods that create various resources.
`TextResourceFactory` | Creates `TextResource`s backed by sources such as strings, files, and archive entries.
`InputChanges` | Provides access to any input files that need to be processed by an incremental work action.
`Distribution` | A distribution allows to bundle an application or a library including dependencies, sources...

## Publishing types

Listed below are the types used to configure publishing:

Type | Description
`PublishingExtension` | The configuration of how to "publish" the different components of a project.
`IvyPublication` | An `IvyPublication` is the representation/configuration of how Gradle should publish something in Ivy format, to an Ivy repository. You directly add a named Ivy publication the project's `publishing.publications` container by providing `IvyPublication` as the type.
`IvyArtifact` | An artifact published as part of a `IvyPublication`.
`IvyArtifactSet` | A Collection of `IvyArtifact`s to be included in an `IvyPublication`. Being a `DomainObjectSet`, an `IvyArtifactSet` provides convenient methods for querying, filtering, and applying actions to the set of `IvyArtifact`s.

`IvyModuleDescriptorAuthor` | An author of an Ivy publication.
`IvyModuleDescriptorLicense` | A license of an Ivy publication.
`IvyModuleDescriptorDescription` | The description of an Ivy publication.
`MavenPublication` | A `MavenPublication` is the representation/configuration of how Gradle should publish something in Maven format. You directly add a named Maven publication the project's `publishing.publications` container by providing `MavenPublication` as the type.
`MavenArtifact` | An artifact published as part of a `MavenPublication`.
`MavenArtifactSet` | A Collection of `MavenArtifact`s to be included in a `MavenPublication`. Being a `DomainObjectSet`, a `MavenArtifactSet` provides convenient methods for querying, filtering, and applying actions to the set of `MavenArtifact`s.

## Container types

Container types that handle various declarative elements (e.g. dependencies, configurations, artifacts, tasks, etc.):

Type | Description
`TaskContainer` | A `TaskContainer` is responsible for managing a set of `Task` instances.
`ConfigurationContainer` | A `ConfigurationContainer` is responsible for declaring and managing configurations. See also `Configuration`.
`RepositoryHandler` | A `RepositoryHandler` manages a set of repositories, allowing repositories to be defined and queried.
`DependencyHandler` | A `DependencyHandler` is used to declare dependencies. Dependencies are grouped into configurations (see `Configuration`).
`ComponentMetadataHandler` | Allows the build to provide rules that modify the metadata of depended-on software components. Component metadata rules are applied in the components section of the dependencies block `DependencyHandler` of a build script. The rules can be defined in two different ways:
`ArtifactHandler` | This class is for defining artifacts to be published and adding them to configurations. Creating publish artifacts does not mean to create an archive. What is created is a domain object which represents a file to be published and information on how it should be published (e.g. the name).

## Authentication types

Credentials and Authentication types for connecting to repositories:

Type | Description
`AuthenticationSupported` | An artifact repository which supports username/password authentication.
`Credentials` | Base interface for credentials used for different authentication purposes. (e.g authenticated `RepositoryHandler`)
`PasswordCredentials` | A username/password credentials that can be used to login to password-protected remote repository.
`AwsCredentials` | Represents credentials used to authenticate with Amazon Web Services.
`HttpHeaderCredentials` | Credentials that can be used to login to a protected server, e.g. a remote repository by using HTTP header. The properties used for creating credentials from a property are `repoAuthHeaderName` and `repoAuthHeaderValue`, where `repo` is the identity of the repository.
`AuthenticationContainer` | Container for configuring repository authentication schemes of type `Authentication`.

## Help Task types

Below are the task types that are available for every Gradle project. Those task types can also be declared and configured directly in the build script.

Type | Description

This is useful for listing what a project produces in terms of variants and what artifacts are attached to each variant. Variants, in this context, must be understood as "things produced by a project which can safely be consumed by another project".
`ResolvableConfigurationsReportTask` | A task which reports the configurations of a project which can be resolved on the command line. This is useful for determining which attributes are associated with the resolvable configurations being used to resolve a project's dependencies. The output can help predict which variant of each dependency will be resolved.
