```Python hl_lines="6-9"
{!../../../docs_src/background_tasks/tutorial001.py!}
```

## Добавление фоновой задачи

Внутри функции вызовите метод `.add_task()` у объекта *background tasks* и передайте ему функцию, которую хотите выполнить в фоне:

```Python hl_lines="14"
{!../../../docs_src/background_tasks/tutorial001.py!}
```

`.add_task()` принимает следующие аргументы:

    doLast {
        println("Hello world!")
    }
}
----

Once the task is assigned to a group, it will be listed by `./gradlew tasks`:

[source]
----
$ ./gradlew tasks

> Task :tasks

Custom tasks
------------------
hello - A lovely greeting task.
----

To view information about a task, use the `help --task <task-name>` command:

[source]

# tag::cli[]
# gradle --quiet task1
# end::cli[]
executable: gradle
args: task1
flags: --quiet

 *
 *     {@literal @}BinaryTasks
 *     void createBinaryTasks(ModelMap<Task> tasks, SampleBinary binary) {
 *         tasks.create("${binary.name}Task1", MyCustomBinaryCreationTask)
 *         tasks.create("${binary.name}Task2") {
 *             dependsOn "${binary.name}Task1"
 *         }
 *     }
 * }
 * </pre>
