Package org.gradle.api

## Interface Project

- All Superinterfaces:
    `java.lang.Comparable<Project>`, `ExtensionAware`, `PluginAware`

      public interface Project
      extends java.lang.Comparable<Project>, ExtensionAware, PluginAware

  This interface is the main API you use to interact with Gradle from your build file. From a `Project`, you have programmatic access to all of 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 projects are evaluated in breadth-wise order, such that a project is evaluated before its child projects. This order can be overridden by calling ``evaluationDependsOnChildren()`` or by adding an explicit evaluation dependency using ``evaluationDependsOn(String)``.

  ### 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 `create()` methods on `TaskContainer`, such as `TaskContainer.create(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 `ConfigurationContainer` 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.

  ### Plugins

  Plugins can be used to modularise and reuse project configuration. Plugins can be applied using the `PluginAware.apply(java.util.Map)` method, or by using the `PluginDependenciesSpec` plugins script block.

  ### Dynamic Project Properties

  Gradle executes the project's build file against the `Project` instance to configure the project. Any property or method which your script uses 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()
       reportsDir = file('reports') // Delegates to Project.file() and the Java Plugin

  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.

  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 accessible 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 extra properties of the project. Each project maintains a map of extra properties, which can contain any arbitrary name -> value pair. Once defined, the properties of this scope are readable and writable. See extra properties for more details.
  - The extensions added to the project by the plugins. Each extension is available as a read-only property with the same name as the extension.
  - The convention properties added to the project by the plugins. 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 accessible by using its name as a property name. The properties of this scope are read-only. For example, a task called `compile` is accessible as the `compile` property.
  - The extra properties and convention properties are inherited from the project's parent, 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. If not found, an exception is thrown. 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, an exception is thrown. See `setProperty(String, Object)` for more details.

  #### Extra Properties

  All extra properties must be defined through the "ext" namespace. Once an extra property has been defined, it is available directly on the owning object (in the below case the Project, Task, and sub-projects respectively) and can be read and updated. Only the initial declaration that needs to be done via the namespace.

       project.ext.prop1 = "foo"
       task doStuff {
           ext.prop2 = "bar"
       }
       subprojects { ext.${prop3} = false }

  Reading extra properties is done through the "ext" or through the owning object.

       ext.isSnapshot = version.endsWith("-SNAPSHOT")
       if (isSnapshot) {
           // do snapshot stuff
       }

  #### 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 extensions added to the project by the plugins. Each extension is available as a method which takes a closure or `Action` as a parameter.
  - The convention methods added to the project by the plugins. 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 or `Action` 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 methods of the parent project, recursively up to the root project.
  - A property of the project whose value is a closure. The closure is treated as a method and called with the provided parameters. The property is located as described above.

    - #### getStatus

          java.lang.Object getStatus()

      Returns the status of this project. Gradle always uses the `toString()` value of the status. The status defaults to "release".

      The status of the project is only relevant, if you upload libraries together with a module descriptor. The status specified here, will be part of this module descriptor.

      Returns:
        The status of this project. Never returns null.

                    throws MissingPropertyException

      Sets a property of this project. This method searches for a property with the given name in the following locations, and sets the property on the first location where it finds the property.

      1. The project object itself. For example, the `rootDir` project property.
      2. The project's `Convention` object. For example, the `srcRootName` java plugin property.
      3. The project's extra properties.
      If the property is not found, a `MissingPropertyException` is thrown.
      Parameters:
        `name` - The name of the property
        `value` - The value of the property
      Throws:
        `MissingPropertyException`

    - #### getProject

          Project getProject()

      Returns this project. This method is useful in build files to explicitly access project properties and methods.

      - A `CharSequence`, including `String` or `GString`. Interpreted relative to the project directory. A string that starts with `file:` is treated as a file URL.
      - A `File`. If the file is an absolute file, it is returned as is. Otherwise, the file's path is interpreted relative to the project directory.
      - A `Path`. The path must be associated with the default provider and is treated the same way as an instance of `File`.
      - A `URI` or `URL`. The URL's path is interpreted as the file path. Only `file:` URLs are supported.
      - A `Directory` or `RegularFile`.
      - A `Provider` of any supported type. The provider's value is resolved recursively.
      - A `TextResource`.
      - A Groovy `Closure` or Kotlin function that returns any supported type. The closure's return value is resolved recursively.
      - A `Callable` that returns any supported type. The callable's return value is resolved recursively.
      Parameters:
        `path` - The object to resolve as a File.

    - #### files

          ConfigurableFileCollection files​(java.lang.Object... paths)

      Returns a `ConfigurableFileCollection` containing the given files. You can pass any of the following types to this method:

      - A `CharSequence`, including `String` or `GString`. Interpreted relative to the project directory, as per `file(Object)`. A string that starts with `file:` is treated as a file URL.
      - A `File`. Interpreted relative to the project directory, as per `file(Object)`.
      - A `Path`, as per `file(Object)`.
      - A `URI` or `URL`. The URL's path is interpreted as a file path. Only `file:` URLs are supported.
      - A `Directory` or `RegularFile`.
      - A `Collection`, `Iterable`, or an array that contains objects of any supported type. The elements of the collection are recursively converted to files.
      - A `FileCollection`. The contents of the collection are included in the returned collection.
      - A `FileTree` or `DirectoryTree`. The contents of the tree are included in the returned collection.
      - A `Provider` of any supported type. The provider's value is recursively converted to files. If the provider represents an output of a task, that task is executed if the file collection is used as an input to another task.
      - A `Callable` that returns any supported type. The return value of the `call()` method is recursively converted to files. A `null` return value is treated as an empty collection.
      - A Groovy `Closure` or Kotlin function that returns any of the types listed here. The return value of the closure is recursively converted to files. A `null` return value is treated as an empty collection.
      - A `Task`. Converted to the task's output files. The task is executed if the file collection is used as an input to another task.
      - A `TaskOutputs`. Converted to the output files the related task. The task is executed if the file collection is used as an input to another task.
      - Anything else is treated as an error.

      The returned file collection is lazy, so that the paths are evaluated only when the contents of the file collection are queried. The file collection is also live, so that it evaluates the above each time the contents of the collection is queried.

      The returned file collection maintains the iteration order of the supplied paths.

      The returned file collection maintains the details of the tasks that produce the files, so that these tasks are executed if this file collection is used as an input to some task.

      This method can also be used to create an empty collection, which can later be mutated to add elements.

      Parameters:
        `paths` - The paths to the files. May be empty.
      Returns:
        The file collection. Never returns null.

              exclude '**/.data/**'
              builtBy 'someTask'
           }

           task copy(type: Copy) {
              from myTree
           }

      The returned file tree is lazy, so that it scans for files only when the contents of the file tree are queried. The file tree is also live, so that it scans for files each time the contents of the file tree are queried.

      The order of the files in a `FileTree` is not stable, even on a single computer.

      Parameters:
        `baseDir` - The base directory of the file tree. Evaluated as per `file(Object)`.
        `configureAction` - Action to configure the `ConfigurableFileTree` object.
      Returns:
        the configured file tree. Never returns null.

        3.5

    - #### fileTree

          ConfigurableFileTree fileTree​(java.util.Map<java.lang.String,​?> args)

      Creates a new `ConfigurableFileTree` using the provided map of arguments. The map will be applied as properties on the new file tree. Example:

           def myTree = fileTree(dir:'src', excludes:['**/ignore/**', '**/.data/**'])

           task copy(type: Copy) {
               from myTree
           }

      The returned file tree is lazy, so that it scans for files only when the contents of the file tree are queried. The file tree is also live, so that it scans for files each time the contents of the file tree are queried.

      The order of the files in a `FileTree` is not stable, even on a single computer.

      Parameters:
        `args` - map of property assignments to `ConfigurableFileTree` object
      Returns:
        the configured file tree. Never returns null.

    - #### zipTree

          FileTree zipTree​(java.lang.Object zipPath)

      Creates a new `FileTree` which contains the contents of the given ZIP file. The given zipPath path is evaluated as per `file(Object)`. You can combine this method with the `copy(Action)` method to unzip a ZIP file.

      The returned file tree is lazy, so that it scans for files only when the contents of the file tree are queried. The file tree is also live, so that it scans for files each time the contents of the file tree are queried.

      Parameters:
        `zipPath` - The ZIP file. Evaluated as per `file(Object)`.
      Returns:
        the file tree. Never returns null.

    - #### tarTree

          FileTree tarTree​(java.lang.Object tarPath)

      Creates a new `FileTree` which contains the contents of the given TAR file. The given tarPath path can be:
      - an instance of `Resource`
      - any other object is evaluated as per `file(Object)`
      The returned file tree is lazy, so that it scans for files only when the contents of the file tree are queried. The file tree is also live, so that it scans for files each time the contents of the file tree are queried.

      Unless custom implementation of resources is passed, the tar tree attempts to guess the compression based on the file extension.

      You can combine this method with the `copy(Action)` method to untar a TAR file:

           task untar(type: Copy) {
             from tarTree('someCompressedTar.gzip')

             //tar tree attempts to guess the compression based on the file extension
             //however if you must specify the compression explicitly you can:
             from tarTree(resources.gzip('someTar.ext'))

             //in case you work with unconventionally compressed tars
             //you can provide your own implementation of a ReadableResource:
             //from tarTree(yourOwnResource as ReadableResource)

             into 'dest'
           }

      Parameters:
        `tarPath` - The TAR file or an instance of `Resource`.
      Returns:
        the file tree. Never returns null.

      Configures an object via a closure, with the closure's delegate set to the supplied object. This way you don't have to specify the context of a configuration statement multiple times.

      Instead of:

           MyType myType = new MyType()
           myType.doThis()
           myType.doThat()

      you can do:

           MyType myType = configure(new MyType()) {
               doThis()
               doThat()
           }

      The object being configured is also passed to the closure as a parameter, so you can access it explicitly if required:

           configure(someObj) { obj -> obj.doThis() }

      Parameters:
        `object` - The object to configure
        `configureClosure` - The closure with configure statements
      Returns:
        The configured object
