# Class FTPTask

java.lang.Object
org.apache.tools.ant.ProjectComponent
org.apache.tools.ant.Task
org.apache.tools.ant.taskdefs.optional.net.FTPTask

All Implemented Interfaces:
  `Cloneable`

public class FTPTask extends Task
Basic FTP client. Performs the following actions:

- send - send files to a remote server. This is the default action.
- get - retrieve files from a remote server.
- del - delete files from a remote server.
- list - create a file listing.
- chmod - change unix file permissions.
- rmdir - remove directories, if empty, from a remote server.

Note: Some FTP servers - notably the Solaris server - seem to hold data ports open after a "retr" operation, allowing them to timeout instead of shutting them down cleanly. This happens in active or passive mode, and the ports will remain open even after ending the FTP session. FTP "send" operations seem to close ports immediately. This behavior may cause problems on some systems when downloading large sets of files.

Since:
  Ant 1.3
