## Interface TaskContainer

- All Superinterfaces:
    Collection<Task>, org.gradle.util.Configurable<NamedDomainObjectContainer<Task>>, DomainObjectCollection<Task>, Iterable<Task>, NamedDomainObjectCollection<Task>, NamedDomainObjectContainer<Task>, NamedDomainObjectSet<Task>, Set<Task>, TaskCollection<Task>

      public interface TaskContainer
      extends TaskCollection<Task>, NamedDomainObjectContainer<Task>

  A `TaskContainer` is responsible for managing a set of `Task` instances.

  You can obtain a `TaskContainer` instance by calling `Project.getTasks()`, or using the `tasks` property in your build script.
