<title>SetPermissions Task</title>
</head>

<body>

<h2><a name="setpermissions">SetPermissions</a></h2>
<p><em>Since Ant 1.10.0.</em></p>
<h3>Description</h3>
<p>Changes the file permissions using Java's NIO support for
  permissions.</p>
<p>This task provides a subset of the platform specific abilities of
  <a href="chmod.html">chmod</a> and <a href="attrib.html">attrib</a>
  in a platform independent way.</p>
<p>If no permissions are specified either via the mode or the
  permissions attribute, then all permissions will be removed from the
  nested resources.</p>
<p>The task accepts aribitrary resources as part of the nested
  resource collections, but not all resources support setting
  permissions. This task won't do anything for resources that don't
  support setting permissions - for example URLs.</p>
<p>The permissions are applied to all resources contained within the
  nested resources collections. You may want to ensure the collection
  only returns files or directories if you want different sets of
  permissions to apply to either type of resource.</p>
