org.apache.tools.ant.taskdefs.Sync

All Implemented Interfaces:

Cloneable

public class Sync
extends Task

Synchronize a local target directory from the files defined in one or more filesets.

Uses a <copy> task internally, but forbidding the use of mappers and filter chains. Files of the destination directory not present in any of the source fileset are removed.

Since:

Ant 1.6 revised by Dan Armbrust to remove orphaned directories.
