| <h2><a name="get">Sync</a></h2> |
| <p><em>Since Ant 1.6</em></p> |
| <h3>Description</h3> |
| |
| <p>Synchronize a target directory from the files defined in one or |
| more <a href="../CoreTypes/resources.html#collection">Resource Collection</a>s.</p> |
| |
| <p>Any file in the target directory that has not been matched by at |
| least one of the nested resource collections gets removed. I.e. if you exclude a |
| file in your sources and a file of that name is present in the target |
| dir, it will get removed from the target.</p> |
| |

| millisecond level. Default is 0 milliseconds, or 2 seconds on DOS |
| systems. This can also be useful if source and target files live |
| on separate machines with clocks being out of sync. <em>since Ant |
| 1.6.2</em>.</td> |

| <h3>Parameters specified as nested elements</h3> |
| |
| <h4>fileset or any other resource collection</h4> |
| <p><a href="../CoreTypes/resources.html#collection">Resource |
| Collection</a>s are used to select groups of files to copy. To use a |
| resource collection, the <code>todir</code> attribute must be set.</p> |
| <p>Prior to Ant 1.7 only <code><fileset></code> has been |
| supported as a nested element.</p> |
| |
| <h4>preserveInTarget</h4> |
| |
| <p>Specifies files or directories that should be kept in the target |
| directory even if they are not present in one of the source |
| directories.</p> |
| |
| <p>This nested element is like a <a |
| href="../CoreTypes/fileset.html">FileSet</a> except that it doesn't |
| support the dir attribute and the usedefaultexcludes attribute |
| defaults to false.</p> |
| |
| <h3>Examples</h3> |
| |
| <blockquote><pre> |
| <sync todir="site"> |
| <fileset dir="generated-site"/> |
| </sync> |
| </pre></blockquote> |
| <p>overwrites all files in <em>site</em> with newer files from |
| <em>generated-site</em>, deletes files from <em>site</em> that are not |
| present in <em>generated-site</em>.</p> |
| |
| <blockquote><pre> |
| <sync todir="site"> |
| <fileset dir="generated-site"/> |
| <preserveintarget> |
| <include name="**/CVS/**"/> |
| </preserveintarget> |
| </sync> |
| </pre></blockquote> |
| <p>overwrites all files in <em>site</em> with newer files from |
| <em>generated-site</em>, deletes files from <em>site</em> that are not |
| present in <em>generated-site</em> but keeps all files in any |
| <em>CVS</em> sub-directory.</p> |
