Interface Project

All Superinterfaces:
java.lang.Comparable<Project>

public interface Project
extends java.lang.Comparable<Project>

This interface is the main API you use to interact with Gradle from your build file. From a Project, you can programmatically access all Gradle's features.

Lifecycle

There is a one-to-one relationship between a Project and a "build.gradle" file. During build initialisation, Gradle assembles a Project object for each project which is to participate in the build, as follows:

Tasks

A project is essentially a collection of Task objects. Each task performs some basic piece of work, such as compiling classes, or running unit tests, or zipping up a WAR file. You add tasks to a project using one of the add() methods on TaskContainer, such as TaskContainer.add(String). You can locate existing tasks using one of the lookup methods on TaskContainer, such as TaskCollection.getByName(String).

Dependencies

A project generally has a number of dependencies it needs in order to do its work. Also, a project generally produces a number of artifacts, which other projects can use. Those dependencies are grouped in configurations, and can be retrieved and uploaded from repositories. You use the ConfigurationHandler returned by getConfigurations() ()} method to manage the configurations. The DependencyHandler returned by getDependencies() method to manage the dependencies. The ArtifactHandler returned by getArtifacts() ()} method to manage the artifacts. The RepositoryHandler returned by getRepositories() ()} method to manage the repositories.

Multi-project Builds

Projects are arranged into a hierarchy of projects. A project has a name, and a fully qualified path which uniquely identifies it in the hierarchy.

Using a Project in a Build File

Gradle executes the project's build file against the Project instance to configure the project. Any property or method which your script uses which is not defined in the script is delegated through to the associated Project object. This means, that you can use any of the methods and properties on the Project interface directly in your script.

For example:

 defaultTasks('some-task')  // Delegates to Project.defaultTasks()
 reportDir = file('reports') // Delegates to Project.file() and Project.setProperty()
 

You can also access the Project instance using the project property. This can make the script clearer in some cases. For example, you could use project.name rather than name to access the project's name.

Dynamic Properties

A project has 5 property 'scopes', which it searches for properties. You can access these properties by name in your build file, or by calling the project's property(String) method. The scopes are:

When reading a property, the project searches the above scopes in order, and returns the value from the first scope it finds the property in. See property(String) for more details.

When writing a property, the project searches the above scopes in order, and sets the property in the first scope it finds the property in. If not found, the project adds the property to its map of additional properties. See setProperty(String, Object) for more details.

Dynamic Methods

A project has 5 method 'scopes', which it searches for methods:

You can access this property in your build file using name

Returns:
The name of this project. Never return null.

getGroup

java.lang.Object getGroup()

Parameters:
args - The task creation options.
name - The name of the task to be created
action - The closure to be passed to the Task.doFirst(Closure) method of the created task.
