Use a <a href="../CoreTypes/zipfileset.html">zipfileset</a> or <a href="../CoreTasks/zip.html#zipgroupfileset">zipgroupfileset</a> with the <a href="../CoreTasks/jar.html">Jar task</a> or <a href="../CoreTasks/zip.html">Zip task</a> instead.</i></p> <h3><b>Description:</b></h3> <p>Links entries from sub-builds and libraries.</p> <p>The jlink task can be used to build jar and zip files, similar to the <i>jar</i> task. However, jlink provides options for controlling the way entries from input files are added to the output file. Specifically, capabilities for merging entries from multiple zip or jar files is available.</p> <p>If a mergefile is specified directly (eg. at the top level of a <i>mergefiles</i> pathelement) <i>and</i> the mergefile ends in ".zip" or ".jar", entries in the mergefile will be merged into the outfile. A file with any other extension will be added to the output file, even if it is specified in the mergefiles element. Directories specified in either the mergefiles or addfiles element are added to the output file as you would expect: all files in subdirectories are recursively added to the output file with appropriate prefixes in the output file (without merging). </p> <p> In the case where duplicate entries and/or files are found among the files to be merged or added, jlink merges or adds the first entry and ignores all subsequent entries. </p> <p> jlink ignores META-INF directories in mergefiles. Users should supply their own manifest information for the output file. </p> <p>It is possible to refine the set of files that are being jlinked. This can be done with the <i>includes</i>, <i>includesfile</i>, <i>excludes</i>, <i>excludesfile</i>, and <i>defaultexcludes</i> attributes on the <i>addfiles</i> and <i>mergefiles</i> nested elements. With the <i>includes</i> or <i>includesfile</i> attribute you specify the files you want to have included by using patterns. The <i>exclude</i> or <i>excludesfile</i> attribute is used to specify the files you want to have excluded. This is also done with patterns. And finally with the <i>defaultexcludes</i> attribute, you can specify whether you want to use default exclusions or not. See the section on <a href="../dirtasks.html#directorybasedtasks">directory based tasks</a>, on how the inclusion/exclusion of files works, and how to write patterns. The patterns are relative to the <i>base</i> directory.</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">outfile</td> <td valign="top">the path of the output file.</td> <td valign="top" align="center">Yes</td> </tr> <tr> <td valign="top">compress</td> <td valign="top">whether or not the output should be compressed. <i>true</i>, <i>yes</i>, or <i>on</i> result in compressed output.
