/**
* Declares the configuration required to instantiate and configure the hierarchy of {@link
* org.gradle.api.Project} instances which are to participate in a build.
*
* There is a one-to-one correspondence between a Settings instance and a {@value
* #DEFAULT_SETTINGS_FILE} 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 {@link #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 {@link 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 {@code Settings} object makes some additional read-only
* properties available to the settings script. This includes properties from the following sources:
*
*
*
* - Defined in the {@value org.gradle.api.Project#GRADLE_PROPERTIES} file located in the settings directory of the
* build.
*
* - Defined the {@value org.gradle.api.Project#GRADLE_PROPERTIES} file located in the user's {@code .gradle}
* directory.
*
* - Provided on the command-line using the -P option.
