<title>MultiRooFileSet Type</title>

<h2><a name="multirootfileset">MultiRootFileSet</a></h2>

<p><em>Since Ant 1.9.4</em></p>

<p>A MultiRootFileSet is a group of files or directories. These files
or drectories can be found in a directory forrest starting with a set
of base directories and are matched by patterns taken from a number of
<a href="patternset.html">PatternSets</a> and <a
href="selectors.html">Selectors</a>.</p>

<p>MultiRootFileSet acts as a union of <a
href="fileset.html">FileSets</a> and <a href="dirset.html">DirSets</a>
that share the same patterns and selectors.</p>

<p>MultiRootFileSet supports all attributes and nested elements of
FileSet and DirSet except for the "dir" attribute.</p>

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

<p>PatternSets can be specified as nested
<code>&lt;patternset&gt;</code> elements. In addition, MultiRootFileSet holds
an implicit PatternSet and supports the nested
<code>&lt;include&gt;</code>, <code>&lt;includesfile&gt;</code>,
<code>&lt;exclude&gt;</code> and <code>&lt;excludesfile&gt;</code>
elements of <code>&lt;patternset&gt;</code> directly, as well as
<code>&lt;patternset&gt;</code>'s attributes.</p>

<p>Selectors are available as nested elements within the
MultiRootFileSet. If any of the selectors within the MultiRootFileSet
do not select the file or directory, it is not considered part of the
MultiRootFileSet. This makes a MultiRootFileSet equivalent to
an <code>&lt;and&gt;</code> selector container.</p>

<p>In addition basedirs for the MultiRootFileSet can be specified as
nested <code>basedir</code> elements that have a
single <code>file</code> attribute.</p>


<h4>Examples</h4>

<blockquote><pre>
&lt;multirootfileset basedirs=&quot;${build.dir},${other.project.dir}&quot;&gt;
&lt;include name=&quot;apps/**/classes&quot;/&gt;
&lt;exclude name=&quot;apps/**/*Test*&quot;/&gt;
&lt;/multirootfileset&gt;
</pre></blockquote>
<p>Groups all files inside <code>classes</code> found under the
<code>apps</code> subdirectory of <code>${build.dir}</code> or
<code>${other.project.dir}</code>, except those that have the text
<code>Test</code> in their name.</p>

<blockquote><pre>
&lt;multirootfileset&gt;
&lt;basedir file=&quot;${build.dir}&quot;/&gt;
&lt;basedir file=&quot;${other.project.dir}&quot;
&lt;include name=&quot;apps/**/classes&quot;/&gt;
&lt;exclude name=&quot;apps/**/*Test*&quot;/&gt;
&lt;/multirootfileset&gt;
</pre></blockquote>
<p>Is equivalent to the first example but used
nested <code>basedir</code> elements. The nested elements and
the <code>basedirs</code> attribute can be used at the same time and
the will be merged.</p>
