<h2 id="setpermissions">SetPermissions</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 arbitrary 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>

||||
