<title>Sync Task</title>
</head>
<body>
<h2 id="get">Sync</h2>
<p><em>Since Apache Ant 1.6</em></p>
<h3>Description</h3>
<p>Synchronize a target directory from the files defined in one or
more <a href="../Types/resources.html#collection">resource collections</a>.</p>
<p>Any file in the target directory that has not been matched by at least one of the nested resource
collections gets removed. I.e. if you exclude a file in your sources and a file of that name is
present in the target dir, it will get removed from the target.</p>
<h3>Parameters</h3>
<table class="attr">
<tr>
<th scope="col">Attribute</th>
<th scope="col">Description</th>
<th scope="col">Required</th>
</tr>
<tr>
<td>todir</td>
<td>the target directory to sync with the resource collections</td>
<td>Yes</td>
</tr>
<tr>
<td>overwrite</td>
<td>Overwrite existing files even if the destination files are newer.</td>
<td>No; defaults to <q>false</q></td>
</tr>
<tr>
<td>includeEmptyDirs</td>
<td>Copy any empty directories included in the resource
collection(s).<br/><strong>Note</strong>: this attribute also controls the behavior for any
nested <code><preserveintarget></code> element. If this attribute is <q>false</q> (the
default) empty directories that only exist in the target directory will be removed even if
they are matched by the patterns of <code><preserveintarget></code>. This can be
overridden by <code><preserveintarget></code>'s <var>preserveEmptyDirs</var>
attribute.</td>
<td>No; defaults to <q>false</q></td>
</tr>
<tr>
<td>failonerror</td>
<td>If set to <q>false</q>, log a warning message, but do not stop the build, when one of the
nested filesets points to a directory that doesn't exist.</td>
<td>No; defaults to <q>true</q></td>
</tr>
<tr>
<td>verbose</td>
<td>Log the files that are being copied.</td>
<td>No; defaults to <q>false</q></td>
</tr>
<tr>
<td>granularity</td>
<td>The number of milliseconds leeway to give before deciding a file is out of date. This is
needed because not every file system supports tracking the last modified time to the
millisecond level. This can also be useful if source and target files live on separate
machines with clocks being out of sync. <em>since Ant 1.6.2</em>.</td>
<td>No; default is 0 milliseconds, or 2 seconds on DOS systems.</td>
</tr>
</table>
<h3>Parameters specified as nested elements</h3>
<h4>any resource collection</h4>
<p><a href="../Types/resources.html#collection">resource collections</a> are used to select groups
of files to copy.</p>
<p>Prior to Ant 1.7 only <code><fileset></code> has been supported as a nested element.</p>
<h4>preserveInTarget</h4>
<p><em>Since Ant 1.7.0</em></p>
<p>Specifies files or directories that should be kept in the target directory even if they are not
present in one of the source directories.</p>
<p>This nested element is like a <a href="../Types/fileset.html">FileSet</a> except that it doesn't
support the <var>dir</var> attribute and the <var>usedefaultexcludes</var> attribute defaults
to <q>false</q>.</p>
<h5>Additional parameters</h5>
<table class="attr">
<tr>
<th scope="col">Attribute</th>
<th scope="col">Description</th>
<th scope="col">Required</th>
</tr>
<tr>
<td>preserveEmptyDirs</td>
<td>Overrules the <var>includeEmptydirs</var> setting for directories matched by this element.
If you want to preserve empty directories that are not in your source directory you can either
set the task's <var>includeemptydirs</var> attribute or this one. If the two attribute values
conflict, this attribute "wins".</td>
<td>No; defaults to the value of the task's <var>includeemptydirs</var> attribute</td>
</tr>
</table>
