## org.gradle.api
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:

- Create a `Settings` instance for the build.
- Evaluate the `"settings.gradle"` script, if present, against the `Settings` object to configure it.
- Use the configured `Settings` object to create the hierarchy of `Project` instances.
- Finally, evaluate each `Project` by executing its `"build.gradle"` file, if present, against the project. The project are evaulated in breadth-wise order, such that a project is evaulated before its child projects. This order can be overridden by adding an evaluation dependency.

### 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:

     createTask('some-task')  // Delegates to Project.createTask()
     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:

- The `Project` object itself. This scope includes any property getters and setters declared by the `Project` implementation class. For example, `getRootProject()` is accessable as the `rootProject` property. The properties of this scope are readable or writable depending on the presence of the corresponding getter or setter method.
- The additional properties of the project. Each project maintains a map of additional properties, which can contain any arbitrary name -> value pair. The properties of this scope are readable and writable.
- The convention properties added to the project by each `Plugin` applied to the project. A `Plugin` can add properties and methods to a project through the project's `Convention` object. The properties of this scope may be readable or writable, depending on the convention objects.
- The tasks of the project. A task is accessable by using its name as a property name. The properties of this scope are read-only. For example, a task called `compile` is accessable as the `compile` property.
- The additional properties and convention properties of the project's parent project, recursively up to the root project. The properties of this scope are read-only.

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:

- The `Project` object itself.
- The build file. The project searches for a matching method declared in the build file.
- The convention methods added to the project by each `Plugin` applied to the project. A `Plugin` can add properties and method to a project through the project's `Convention` object.
- The tasks of the project. A method is added for each task, using the name of the task as the method name and taking a single closure parameter. The method calls the `Task.configure(groovy.lang.Closure)` method for the associated task with the provided closure. For example, if the project has a task called `compile`, then a method is added with the following signature: `void compile(Closure configureClosure)`.
- The parent project, recursively up to the root project.
