-[[features-task-name]]
-=== Task Name
-
-In most cases, the name of the task is the application name as configured in Spring
-Boot. However, there are some cases where you may want to map the run of a task to a
-different name. Spring Cloud Data Flow is an example of this (because you probably want
-the task to be run with the name of the task definition). Because of this, we offer the
-ability to customize how the task is named, through the `TaskNameResolver` interface.
-
-By default, Spring Cloud Task provides the `SimpleTaskNameResolver`, which uses the
-following options (in order of precedence):
-
-. A Spring Boot property (configured in any of the ways Spring Boot allows) called
-`spring.cloud.task.name`.
-. The application name as resolved using Spring Boot's rules (obtained through
-`ApplicationContext#getId`).
