Settings (Gradle API 1.4)

```
public interface Settings
```
Declares the configuration required to instantiate and configure the hierarchy of Project instances which are to participate in a build.

There is a one-to-one correspondence between a Settings instance and a "settings.gradle" settings file. Before Gradle assembles the projects for a build, it creates a Settings instance and executes the settings file against it.

Assembling a Multi-Project Build

One of the purposes of the Settings object is to allow you to declare the projects which are to be included in the build. You add projects to the build using the include(String[]) method. There is always a root project included in a build. It is added automatically when the Settings object is created. The root project's name defaults to the name of the directory containing the settings file. The root project's project directory defaults to the directory containing the settings file.

When a project is included in the build, a ProjectDescriptor is created. You can use this descriptor to change the default values for several properties of the project.

Using Settings in a Settings File

Dynamic Properties

In addition to the properties of this interface, the Settings object makes some additional read-only properties available to the settings script. This includes properties from the following sources:
- Defined in the "gradle.properties" file located in the settings directory of the build.
- Defined the "gradle.properties" file located in the user's .gradle directory.
- Provided on the command-line using the -P option.

static final String DEFAULT_SETTINGS_FILE
```
    The default name for the settings file.

- Method Detail
  - include
```
void include(String[] projectPaths)
```
    Adds the given projects to the build. Each path in the supplied list is treated as the path of a project to add to the build. Note that these path are not file paths, but instead specify the location of the new project in the project heirarchy. As such, the supplied paths must use the ':' character as separator.
    
    The last element of the supplied path is used as the project name. The supplied path is converted to a project directory relative to the root project directory.
    
    As an example, the path a:b adds a project with path :a:b, name b and project directory $rootDir/a/b.
    
    Parameters:
    projectPaths - the projects to add.
  - includeFlat
```
void includeFlat(String[] projectNames)
```
    Adds the given projects to the build. Each name in the supplied list is treated as the name of a project to add to the build.
    
    The supplied name is converted to a project directory relative to the parent directory of the root project directory.
    
    As an example, the name a add a project with path :a, name a and project directory $rootDir/../a.
    
    Parameters:
    projectNames - the projects to add.

  - getRootDir
```
File getRootDir()
```
    Returns the root directory of the build. The root directory is the project directory of the root project.
    
    Returns:
    The root directory. Never returns null.
  - getRootProject
```

    Parameters:
    path - The path.
    
    Returns:

  - findProject
```
ProjectDescriptor findProject(String path)
```
    Returns the project with the given path.
    
    Parameters:
    path - The path
    
    Returns:

    Returns the project with the given project directory.
    
    Parameters:
    projectDir - The project directory.
    
    Returns:

```
    Returns the project with the given project directory.
    
    Parameters:
