public interface Task extends Comparable<Task>, ExtensionAware, Named

A `Task` represents a single atomic piece of work for a build, such as compiling classes or generating javadoc.

Each task belongs to a `Project`. You can use the various methods on `TaskContainer` to create and lookup task instances. For example, `TaskContainer.create(String)` creates an empty task with the given name. You can also use the `task` keyword in your build file:

    task myTask
    task myTask { configure closure }
    task myTask(type: SomeType)
    task myTask(type: SomeType) { configure closure }

Each task has a name, which can be used to refer to the task within its owning project, and a fully qualified path, which is unique across all tasks in all projects. The path is the concatenation of the owning project's path and the task's name. Path elements are separated using the ":" character.

## Task Actions

A `Task` is made up of a sequence of `Action` objects. When the task is executed, each of the actions is executed in turn, by calling `Action.execute(T)`. You can add actions to a task by calling `doFirst(Action)` or `doLast(Action)`.

Groovy closures can also be used to provide a task action. When the action is executed, the closure is called with the task as parameter. You can add action closures to a task by calling `doFirst(groovy.lang.Closure)` or `doLast(groovy.lang.Closure)`.

There are 2 special exceptions which a task action can throw to abort execution and continue without failing the build. A task action can abort execution of the action and continue to the next action of the task by throwing a `StopActionException`. A task action can abort execution of the task and continue to the next task by throwing a `StopExecutionException`. Using these exceptions allows you to have precondition actions which skip execution of the task, or part of the task, if not true.

## Task Dependencies and Task Ordering

A task may have dependencies on other tasks or might be scheduled to always run after another task. Gradle ensures that all task dependencies and ordering rules are honored when executing tasks, so that the task is executed after all of its dependencies and any "must run after" tasks have been executed.

Dependencies to a task are controlled using `dependsOn(Object...)` or `setDependsOn(Iterable)`, and `mustRunAfter(Object...)`, `setMustRunAfter(Iterable)`, `shouldRunAfter(Object...)` and `setShouldRunAfter(Iterable)` are used to specify ordering between tasks. You can use objects of any of the following types to specify dependencies and ordering:

- A `String`, `CharSequence` or `groovy.lang.GString` task path or name. A relative path is interpreted relative to the task's `Project`. This allows you to refer to tasks in other projects. These task references will not cause task creation.
- A `Task`.
- A `TaskDependency` object.
- A `TaskReference` object.
- A `Buildable` object.
- A `RegularFileProperty` or `DirectoryProperty`.
- A `Provider` object. May contain any of the types listed here.
- A `Iterable`, `Collection`, `Map` or array. May contain any of the types listed here. The elements of the iterable/collection/map/array are recursively converted to tasks.
- A `Callable`. The `call()` method may return any of the types listed here. Its return value is recursively converted to tasks. A `null` return value is treated as an empty collection.
- A Groovy `Closure` or Kotlin function. The closure or function may return any of the types listed here. Its return value is recursively converted to tasks. A `null` return value is treated as an empty collection.
- Anything else is treated as an error.

## Using a Task in a Build File

### Dynamic Properties

A `Task` has 4 'scopes' for properties. You can access these properties by name from the build file or by calling the `property(String)` method. You can change the value of these properties by calling the `setProperty(String, Object)` method.

- The `Task` object itself. This includes any property getters and setters declared by the `Task` implementation class. The properties of this scope are readable or writable based on the presence of the corresponding getter and setter methods.
- The extensions added to the task by plugins. Each extension is available as a read-only property with the same name as the extension.
- The extra properties of the task. Each task object maintains a map of additional properties. These are arbitrary name -> value pairs which you can use to dynamically add properties to a task object. Once defined, the properties of this scope are readable and writable.

### Parallel Execution

By default, tasks are not executed in parallel unless a task is waiting on asynchronous work and another task (which is not dependent) is ready to execute. Parallel execution can be enabled by the `--parallel` flag when the build is initiated. In parallel mode, the tasks of different projects (i.e. in a multi project build) are able to be executed in parallel.

    You may add multiple such predicates. The task is skipped if any of the predicates return false.

    Since:
      0.7

          }

    The Thread executing this task will be interrupted if the task takes longer than the specified amount of time to run. In order for a task to work properly with this feature, it needs to react to interrupts and must clean up any resources it opened.

  - ### usesService

    void usesService(Provider<? extends BuildService<?>> service)
    Registers a `BuildService` that is used by this task so `its constraint on parallel execution` can be honored.

    Parameters:
      `service` - The service provider.
    Since:
      6.1
    See Also:
      - `ServiceReference`

  - ### service

    @Incubating <T extends TaskService> T service(Class<T> serviceType)
    Looks up a service provided by Gradle for use in this task.

    The services available for lookup are the Gradle types that implement `TaskService`.

    The lookup can be used both at configuration time and from task actions at execution time, and is safe to use with the configuration cache:

        tasks.register("cleanThing") {
            doLast {
                service(FileSystemOperations).delete {
                    delete("thing")
                }
            }
        }

    This method does not provide access to `shared build services`; use `ServiceReference` to access those.

    Type Parameters:
      `T` - the service type
    Parameters:
      `serviceType` - the type of the service to look up
    Returns:
      the service instance. Never returns null.
    Throws:
      `InvalidUserDataException` - when the given type is not one of the services available in this scope
