Get Task

Get

Description

Gets a file from a URL. When the verbose option is "on", this task displays a '.' for every 100 Kb retrieved. Any URL schema supported by the runtime is valid here, including http:, ftp: and jar:; https: is only valid if the appropriate support is added to the pre-1.4 Java runtimes.

This task should be preferred above the CVS task when fetching remote content. CVS is significantly slower than loading a compressed archive compared to http/ftp.

The usetimestamp option enables you to control downloads so that the remote file is only fetched if newer than the local copy. If there is no local copy, the download always takes place. When a file is downloaded, the timestamp of the downloaded file is set to the remote timestamp, if the JVM is Java1.2 or later. NB: This timestamp facility only works on downloads using the HTTP protocol.

A username and password can be specified, in which case basic 'slightly encoded plain text' authentication is used. This is only a secure authentication mechanism over an HTTPS link.

If you need to go through a firewall, use <setproxy> to set up the proxy first.

Parameters

Attribute	Description	Required
src	the URL from which to retrieve a file.	Yes

verbose	show verbose progress information ("on"/"off").	No; default "false"
ignoreerrors	Log errors but don't treat as fatal.	No; default "false"
usetimestamp	conditionally download a file based on the timestamp of the local copy. HTTP only	No; default "false"

Examples

  <get src="http://ant.apache.org/" dest="help/index.html"/>

Gets the index page of http://ant.apache.org/, and stores it in the file help/index.html.

  <get src="http://www.apache.org/dist/ant/KEYS" 
    dest="KEYS" 
    verbose="true"
    usetimestamp="true"/>

Gets the PGP keys of Ant's (current and past) release managers, if the local copy is missing or out of date. Uses the verbose option for progress information.

  <get src="https://insecure-bank.org/statement/user=1214" 
    dest="statement.html" 
    username="1214";
    password="secret"/>

Fetches some file from a server with access control. Because https is being used the fact that basic auth sends passwords in plaintext is moot.
