| <h2><a name="unzip">Unjar/Untar/Unwar/Unzip</a></h2> |
| <h3>Description</h3> |
| <p>Unzips a zip-, war-, or jar file.</p> |
| <p><a href="../CoreTypes/patternset.html">PatternSet</a>s are used to select files to extract |
| <I>from</I> the archive. If no patternset is used, all files are extracted. |
| </p> |
| |
| <p><a href="../CoreTypes/resources.html#collection">Resource |
| Collection</a>s may be used to select archived files to perform |
| unarchival upon. Only file system based resource collections are |
| supported by Unjar/Unwar/Unzip, this includes <a |
| href="../CoreTypes/fileset.html">fileset</a>, <a |
| href="../CoreTypes/filelist.html">filelist</a>, <a |
| href="../using.html#path">path</a>, and <a |
| href="../CoreTypes/resources.html#files">files</a>. |
| Untar supports arbitrary resource collections. |
| Prior to Ant 1.7 only fileset has been supported as a nested element.</p> |
| |
| <p>You can define filename transformations by using a nested <a href="../CoreTypes/mapper.html">mapper</a> element. The default mapper is the |
| <a href="../CoreTypes/mapper.html#identity-mapper">identity mapper</a>. |
| </p> |
| <p>File permissions will not be restored on extracted files.</p> |
| <p>The untar task recognizes the long pathname entries used by GNU tar.<p> |

| <p>The same is also true for <code><untar></code> and |
| <code><tarfileset></code>. <code><copy></code> offers |
| additional features like <a href="../CoreTypes/filterchain.html">filtering files</a> on the fly, |
| allowing a file to be mapped to multiple destinations or a |
| configurable file system timestamp granularity.</p> |
