# Class Sleep

java.lang.Object
org.apache.tools.ant.ProjectComponent
org.apache.tools.ant.Task
org.apache.tools.ant.taskdefs.Sleep

All Implemented Interfaces:
  `Cloneable`

public class Sleep extends Task
Sleep, or pause, for a period of time.

A task for sleeping a short period of time, useful when a build or deployment process requires an interval between tasks.

A negative value can be supplied to any of attributes provided the total sleep time is positive, pending fundamental changes in physics and JVM execution times

Note that sleep times are always hints to be interpreted by the OS how it feels small times may either be ignored or rounded up to a minimum timeslice. Note also that the system clocks often have a fairly low granularity too, which complicates measuring how long a sleep actually took.

Since:
  Ant 1.4
