|

| 28 | <h3>Description</h3>
|
---|
| 29 |
|
---|
| 30 | <p>Changes the modification time of a resource and possibly creates it
|
---|
| 31 | at the same time. In addition to working with a single file, this Task
|
---|
| 32 | can also work on <a href="../CoreTypes/resource.html">resource</a> and
|
---|
| 33 | resource collections (which also includes directories). Prior to Ant
|
---|
| 34 | 1.7 only FileSet or <a href="../CoreTypes/filelist.html">Filelist</a>
|
---|
| 35 | (since Ant 1.6) have been supported.</p>

|
---|
| 82 | <h4>any resource collection</h4>
|
---|
| 83 |
|
---|
| 84 | <p>You can use any number of nested resource collection elements to
|
---|
| 85 | define the resource for this task and refer to resources defined
|
---|
| 86 | elsewhere. <b>Note:</b> resource passed to this task must implement
|
---|
| 87 | the <code>org.apache.tools.ant.types.resources.Touchable</code>
|
---|
| 88 | interface, this is true for all filesystem-based resources like those
|
---|
| 89 | returned by path, fileset ot filelist.</p>
|
---|
| 90 |
|
---|
| 91 | <p>For backwards compatibility directories matched by nested filesets
|
---|
| 92 | will be "touched" as well, use a <type> selector to suppress
|
---|
| 93 | this. This only applies to filesets nested into the task directly,
|
---|
| 94 | not to filesets nested into a path or any other resource
|
---|
| 95 | collection.</p>
|
---|
| 96 |
|
---|
| 97 | <h4>mapper</h4>
|
---|
| 98 | <p><em>Since Ant 1.6.3,</em> a nested <a href="../CoreTypes/mapper.html">
|
---|
| 99 | mapper</a> can be specified. Files specified via nested
|
---|
| 100 | <code>fileset</code>s, <code>filelist</code>s, or the <code>file</code>
|
---|
| 101 | attribute are mapped using the specified mapper. For each file mapped,
|
---|
| 102 | the resulting files are touched. If the original file exists its
|
---|
| 103 | timestamp will be used. Otherwise the task settings (<code>millis</code>,
|
---|
| 104 | <code>datetime</code>) take effect.</p>
|
---|
| 105 | <h3>Examples</h3>
|
---|
| 106 | <pre> <touch file="myfile"/></pre>
|
---|
| 107 | <p>creates <code>myfile</code> if it doesn't exist and changes the
|
---|
| 108 | modification time to the current time.</p>
|
---|
| 109 | <pre> <touch file="myfile" datetime="06/28/2000 2:02 pm"/></pre>
|
---|
| 110 | <p>creates <code>myfile</code> if it doesn't exist and changes the
|
---|
| 111 | modification time to Jun, 28 2000 2:02 pm (14:02 for those used to 24
|
---|
| 112 | hour times).</p>
|
---|
| 113 | <pre> <touch datetime="09/10/1974 4:30 pm">
|
---|
| 114 | <fileset dir="src_dir"/>
|
---|
| 115 | </touch></pre>
|
---|
| 116 | <p>changes the modification time to Oct, 09 1974 4:30 pm of all files and directories
|
---|
| 117 | found in <code>src_dir</code>. </p>
|
---|
| 118 | <pre> <touch file="myfile" datetime="06/28/2000 2:02:17 pm"/></pre>
|
---|
| 119 | <p>creates <code>myfile</code> if it doesn't exist and changes the
|
---|
| 120 | modification time to Jun, 28 2000 2:02:17 pm (14:02:17 for those used to 24
|
---|
| 121 | hour times), if the filesystem allows a precision of one second - a
|
---|
| 122 | time close to it otherwise.</p>
|
---|
| 123 | <pre> <touch file="foo">
|
---|
| 124 | <mapper type="glob" from="foo" to="bar" />
|
---|
| 125 | </touch>
|
---|
| 126 | </pre>
|
---|
| 127 | <p>creates <code>bar</code> if it doesn't exist and changes the
