+<h2 id="defaultexcludes">DefaultExcludes</h2>
+
+<p><em>Since Apache Ant 1.6</em></p>
+
+<h3>Description</h3>
+<p>Alters the default excludes for all subsequent processing in the build, and prints out the
+current default excludes if desired.</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>echo</td>
+    <td>whether or not to print out the default excludes</td>
+    <td><q>true</q> required if no other attribute specified; defaults to <q>false</q></td>
+  </tr>
+  <tr>
+    <td>default</td>
+    <td>go back to hard wired default excludes</td>
+    <td><q>true</q> required if no other attribute is specified</td>
+  </tr>
+  <tr>
+    <td>add</td>
+    <td>the pattern to add to the default excludes</td>
+    <td>if no other attribute is specified</td>
+  </tr>
+  <tr>
+    <td>remove</td>
+    <td>remove the specified pattern from the default excludes</td>
+    <td>if no other attribute is specified</td>
+  </tr>
+</table>
+
+<h3>Examples</h3>
+
+<p>Print out the default excludes</p>
+
+<pre>&lt;defaultexcludes echo=&quot;true&quot;/&gt;</pre>
+
+<p>Print out the default excludes and exclude all <samp>*.bak</samp> files in <strong>all</strong>
+further processing</p>
+
+<pre>&lt;defaultexcludes echo=&quot;true&quot; add=&quot;**/*.bak&quot;/&gt;</pre>
+
+<p>Silently allow several fileset based tasks to operate on emacs backup files and then restore
+normal behavior</p>
+
+<pre>
+&lt;defaultexcludes remove=&quot;**/*~&quot;/&gt;
+
+(do several fileset based tasks here)
+
+&lt;defaultexcludes default=&quot;true&quot;/&gt;</pre>
+
+<h3>Notes</h3>
+<p>By default the pattern <samp>**/.svn</samp> and <samp>**/.svn/**</samp> are set as default
+excludes. Since version 1.3, Subversion supports
+the <a href="https://subversion.apache.org/docs/release-notes/1.3.html#_svn-hack"
+target="_top">&quot;_svn hack&quot;</a>.  That means, that the svn-libraries evaluate environment
+variables and use <samp>.svn</samp> or <samp>_svn</samp> directory regarding to that value. We had
+chosen not to evaluate environment variables to get a more reliable build. Instead you have to
+change the settings by yourself by changing the exclude patterns:</p>
+<pre>
+&lt;defaultexcludes remove=&quot;**/.svn&quot;/&gt;
+&lt;defaultexcludes remove=&quot;**/.svn/**&quot;/&gt;
+&lt;defaultexcludes add=&quot;**/_svn&quot;/&gt;
+&lt;defaultexcludes add=&quot;**/_svn/**&quot;/&gt;
+</pre>
