Settings (Gradle API 7.6.4)

Package org.gradle.api.initialization

## Interface Settings

- All Superinterfaces:
    `ExtensionAware`, `PluginAware`

      public interface Settings
      extends PluginAware, ExtensionAware

  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.

  - ### Method Detail

    - #### include

          default void include​(java.lang.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 hierarchy. As such, the supplied paths must use the ':' character as separator (and NOT '/').

      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. The project directory can be altered by changing the 'projectDir' property after the project has been included (see `ProjectDescriptor.setProjectDir(File)`)

      As an example, the path `a:b` adds a project with path `:a:b`, name `b` and project directory `$rootDir/a/b`. It also adds the a project with path `:a`, name `a` and project directory `$rootDir/a`, if it does not exist already.

      Some common examples of using the project path are:

             // include two projects, 'foo' and 'foo:bar'
             // directories are inferred by replacing ':' with '/'
             include 'foo:bar'

             // include one project whose project dir does not match the logical project path
             include 'baz'
             project(':baz').projectDir = file('foo/baz')

             // include many projects whose project dirs do not match the logical project paths
             file('subprojects').eachDir { dir ->
               include dir.name
               project(":${dir.name}").projectDir = dir
             }

      Parameters:
        `projectPaths` - the projects to add.

    - #### include

          void include​(java.lang.Iterable<java.lang.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 hierarchy.

      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. The project directory can be altered by changing the 'projectDir' property after the project has been included (see `ProjectDescriptor.setProjectDir(File)`)

      As an example, the path `a:b` adds a project with path `:a:b`, name `b` and project directory `$rootDir/a/b`. It also adds the a project with path `:a`, name `a` and project directory `$rootDir/a`, if it does not exist already.

      Some common examples of using the project path are:
