The literal implication of <code><fileset></code> is that directories are not included; however the removal of empty directories can be triggered when using nested filesets by setting the <code>includeEmptyDirs</code> attribute to <i>true</i>. Note that this attribute is meaningless in the context of any of the various resource collection types that <i>do</i> include directories, but that no attempt will be made to delete non-empty directories in any case. Whether a directory is empty or not is decided by looking into the filesystem - include or exclude patterns don't apply here.</p> <p> If you use this task to delete temporary files created by editors and it doesn't seem to work, read up on the <a href="../dirtasks.html#defaultexcludes">default exclusion set</a> in <strong>Directory-based Tasks</strong>, and see the <code>defaultexcludes</code> attribute below. <p>For historical reasons <code><delete dir="x"/></code> is different from <code><delete><fileset dir="x"/></delete></code>, it will try to remove everything inside "x" including "x" itself, not taking default excludes into account, blindly following all symbolic links. If you need more control, use a nested <code><fileset></code>.</p> <h3>Parameters</h3> <table border="1" cellpadding="2" cellspacing="0"> <tr> <td valign="top"><b>Attribute</b></td> <td valign="top"><b>Description</b></td> <td align="center" valign="top"><b>Required</b></td> </tr> <tr> <td valign="top">file</td> <td valign="top">The file to delete, specified as either the simple filename (if the file exists in the current base directory), a relative-path filename, or a full-path filename.</td> <td align="center" valign="middle" rowspan="2">At least one of the two, unless nested resource collections are specified </tr> <tr> <td valign="top">dir</td> <td valign="top">The directory to delete, including all its files and subdirectories.<br> <b>Note:</b> <code>dir</code> is <em>not</em> used to specify a directory name for <code>file</code>; <code>file</code> and <code>dir</code> are independent of each other.<br> <b>WARNING:</b> Do <b>not</b> set <code>dir</code> to <code>"."</code>, <code>"${basedir}"</code>, or the full-pathname equivalent unless you truly <em>intend</em> to recursively remove the entire contents of the current base directory (and the base directory itself, if different from the current working directory).</td> </tr> <tr> <td valign="top">verbose</td> <td valign="top">Whether to show the name of each deleted file.</td> <td align="center" valign="top">No, default "false"</i></td> </tr> <tr> <td valign="top">quiet</td> <td valign="top">If the specified file or directory does not exist, do not display a diagnostic message (unless Ant has been invoked with the <code>-verbose</code> or <code>-debug</code> switches) or modify the exit status to reflect an error. When set to "true", if a file or directory cannot be deleted, no error is reported. This setting emulates the <code>-f</code> option to the Unix <em>rm</em> command.
