In addition to working with a single file, this Task +can also work on <a href="../Types/resources.html">resources</a> and +resource collections (which also includes directories). Prior to Apache Ant +1.7 only FileSet or <a href="../Types/filelist.html">Filelist</a> +(since Ant 1.6) have been supported.</p> + +<p>Ant uses the API of <code>java.io.File</code> to set the last + modification time which has some limitations. For example the + timestamp granularity depends on the operating system and sometimes + the operating system may allow a granularity smaller than + milliseconds. If you need more control you have to fall back to + the <code><exec></code> task and native commands.</p> + +<p>Starting with Ant 1.8.2 Ant will log a warning message if it fails + to change the file modification time. This will happen if you try + to change the modification time of a file you do not own on many + Unix systems, for example.</p> + +<h3>Parameters</h3> +<table border="1" cellpadding="2" cellspacing="0"> + <tr> + <td valign="top"><b>Attribute</b></td> + <td valign="top"><b>Description</b></td> + <td align="center" valign="top"><b>Required</b></td> + </tr> + <tr> + <td valign="top">file</td> + <td valign="top">The name of the file.</td> + <td valign="top" align="center">Unless a nested resource collection element + has been specified.</td> + </tr> + <tr> + <td valign="top">millis</td> + <td valign="top">Specifies the new modification time of the file + in milliseconds since midnight Jan 1 1970.</td> + <td valign="center" align="center" rowspan="2">No--datetime takes + precedence, however if both are omitted the current time is assumed.</td> + </tr> + <tr> + <td valign="top">datetime</td> + <td valign="top">Specifies the new modification time of the file.

This only applies to filesets nested into the task directly, +not to filesets nested into a path or any other resource +collection.</p> + +<h4>mapper</h4> +<p><em>Since Ant 1.6.3,</em> a nested <a href="../Types/mapper.html"> + mapper</a> can be specified. Files specified via nested + <code>fileset</code>s, <code>filelist</code>s, or the <code>file</code> + attribute are mapped using the specified mapper. For each file mapped, + the resulting files are touched. If no time has been specified and + the original file exists its timestamp will be used. + If no time has been specified and the original file does not exist the + current time is used. Since Ant 1.8 the task settings (<code>millis</code>, + and <code>datetime</code>) have priority over the timestamp of the original + file.</p> +<h3>Examples</h3> +<pre> <touch file="myfile"/></pre> +<p>creates <code>myfile</code> if it doesn't exist and changes the +modification time to the current time.</p> +<pre> <touch file="myfile" datetime="06/28/2000 2:02 pm"/></pre> +<p>creates <code>myfile</code> if it doesn't exist and changes the +modification time to Jun, 28 2000 2:02 pm (14:02 for those used to 24 +hour times).</p> +<pre> <touch datetime="09/10/1974 4:30 pm"> + <fileset dir="src_dir"/> + </touch></pre> +<p>changes the modification time to Oct, 09 1974 4:30 pm of all files and directories + found in <code>src_dir</code>. </p> +<pre> <touch file="myfile" datetime="06/28/2000 2:02:17 pm"/></pre> +<p>creates <code>myfile</code> if it doesn't exist and changes the +modification time to Jun, 28 2000 2:02:17 pm (14:02:17 for those used to 24 +hour times), if the filesystem allows a precision of one second - a +time close to it otherwise.</p> +<pre> <touch file="foo"> + <mapper type="glob" from="foo" to="bar" /> + </touch> +</pre> +<p>creates <code>bar</code> if it doesn't exist and changes the +modification time to that of <code>foo</code>.</p> + +<pre> <touch file="foo" datetime="now"> + <mapper type="regexp" from="^src(.*)\.java" to="shadow\1.empty" /> + </touch> +</pre> +<p>creates files in the <code>shadow</code> directory for every java file in the + <code>src</code> directory if it doesn't exist and changes the modification + time of those files to the current time.</p> + + +</body> +</html> |
