<h2 id="fileset">TarFileSet</h2>

<p><code>TarFileSet</code> has been a stand-alone type <em>since Apache Ant 1.7</em>.</p>

<p>A <code>&lt;tarfileset&gt;</code> is a special form of
a <code>&lt;<a href="fileset.html">fileset</a>&gt;</code> which can behave in 2 different ways:</p>
<ul>
  <li>When the <var>src</var> attribute is used&mdash;or a nested resource collection has been
  specified, the tarfileset is populated with tar entries found in the file <var>src</var>.</li>
  <li>When the <var>dir</var> attribute is used, the tarfileset is populated with filesystem files
  found under <var>dir</var>.</li>
</ul>
<p><code>&lt;tarfileset&gt;</code> supports all attributes
of <code>&lt;<a href="fileset.html">fileset</a>&gt;</code> in addition to those listed below.  Note
that tar archives in general don't contain entries with leading slashes so you shouldn't use
include/exclude patterns that start with slashes either.</p>
<p><em>Since Ant 1.7</em>, a tarfileset can be defined with the <var>id</var> attribute and referred
to with the <var>refid</var> attribute.</p>

<p>The <var>fullpath</var> attribute can only be set for filesets that represent a single
file. The <var>prefix</var> and <var>fullpath</var> attributes cannot both be set on the same
fileset.</p>
<p>When using the <var>src</var> attribute, <var>include</var> and <var>exclude</var> patterns may
be used to specify a subset of the archive for inclusion in the archive as with the <var>dir</var>
attribute.</p>

<p>Please note that currently only the <a href="../Tasks/tar.html">tar</a> task uses the permission
and ownership attributes.</p>

<h3>Parameters specified as nested elements</h3>

<h4>any <a href="resources.html">resource</a> or single element resource collection</h4>

<p>The specified resource will be used as src.</p>

<h4>Examples</h4>

<pre>
&lt;copy todir="some-dir"&gt;
 &lt;tarfileset includes="lib/**"&gt;
   &lt;bzip2resource&gt;
     &lt;url url="http://example.org/dist/some-archive.tar.bz2"/&gt;
   &lt;/bzip2resource&gt;
 &lt;/tarfileset&gt;
&lt;/copy&gt;</pre>

<p>downloads the archive <samp>some-archive.tar.bz2</samp>, uncompresses and extracts it on the fly,
copies the contents of the <samp>lib</samp> directory into <samp>some-dir</samp> and discards the
rest of the archive.  File timestamps will be compared between the archive's entries and files
inside the target directory, no files get overwritten unless they are out-of-date.</p>
