# Interface TaskExecutionListener

All Known Implementing Classes:
  `TaskExecutionAdapter`

@Deprecated public interface TaskExecutionListener
Deprecated.
This type is not supported when configuration caching is enabled.

A `TaskExecutionListener` is notified of the execution of the tasks in a build.

You can add a `TaskExecutionListener` to a build using `TaskExecutionGraph.addTaskExecutionListener(TaskExecutionListener)`

This listener type is not supported when the configuration cache is enabled. To receive task completion events in a compatible way, use a `BuildService` that implements `OperationCompletionListener` and register it via `BuildEventsListenerRegistry`.
