| <h2><a name="zip">Zip</a></h2> |
| <h3>Description</h3> |
| <p>Creates a zipfile.</p> |
| <p>The <i>basedir</i> attribute is the reference directory from where to zip.</p> |
| <p>Note that file permissions will not be stored in the resulting zipfile.</p> |
| <p>It is possible to refine the set of files that are being zipped. This can be |
| done with the <i>includes</i>, <i>includesfile</i>, <i>excludes</i>, <i>excludesfile</i> and <i>defaultexcludes</i> |
| attributes. 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. </p> |
| <p>This task forms an implicit <a href="../CoreTypes/fileset.html">FileSet</a> and |
| supports all attributes of <code><fileset></code> |
| (<code>dir</code> becomes <code>basedir</code>) as well as the nested |
| <code><include></code>, <code><exclude></code> and |
| <code><patternset></code> elements.</p> |
| <p>Or, you may place within it nested file sets, or references to file sets. |
| In this case <code>basedir</code> is optional; the implicit file set is <i>only used</i> |
| if <code>basedir</code> is set. You may use any mixture of the implicit file set |
| (with <code>basedir</code> set, and optional attributes like <code>includes</code> |
| and optional subelements like <code><include></code>); explicit nested |
| <code><fileset></code> elements so long as at least one fileset total is specified. The ZIP file will |
| only reflect the relative paths of files <i>within</i> each fileset. The Zip task and its derivatives know a special form of a fileset named zipfileset that has additional attributes (described below). </p> |
| <p>The Zip task also supports the merging of multiple zip files into the zip file. |
| This is possible through either the <i>src</i> attribute of any nested filesets |
| or by using the special nested fileset <i>zipgroupfileset</i>.</p> |
| <p>The <code>update</code> parameter controls what happens if the |
| ZIP file already exists. When set to <code>yes</code>, the ZIP file is |
| updated with the files specified. (New files are added; old files are |
| replaced with the new versions.) When set to <code>no</code> (the |
| default) the ZIP file is overwritten.</p> |
| <p>The <code>whenempty</code> parameter controls what happens when no files match. |
| If <code>skip</code> (the default), the ZIP is not created and a warning is issued. |
| If <code>fail</code>, the ZIP is not created and the build is halted with an error. |
| If <code>create</code>, an empty ZIP file (explicitly zero entries) is created, |
| which should be recognized as such by compliant ZIP manipulation tools.</p> |
| <p>This task will now use the platform's default character encoding |
| for filenames - this is consistent with the command line ZIP tools, |
| but causes problems if you try to open them from within Java and your |
| filenames contain non US-ASCII characters. Use the encoding attribute |
| and set it to UTF8 to create zip files that can safely be read by |
| Java.</p> |

| <h3>Parameters specified as nested elements</h3> |
| <h4>fileset</h4> |
| <p>The zip task supports any number of nested <a |
| href="../CoreTypes/fileset.html"><code><fileset></code></a> elements to specify |
| the files to be included in the archive.</p> |
| <h4>zipfileset</h4> |
| <p>A <code><zipfileset></code> has three additional attributes: <i>prefix</i>, <i>fullpath</i>, and <i>src</i>. The |
| <i>prefix</i> and <i>fullpath</i> attributes modify the location of the files when they are placed |
| inside the archive. If the <i>prefix</i> attribute is set, all files in the fileset are prefixed |
| with that path in the archive. If the <i>fullpath</i> attribute is set, the file described by the fileset is placed at that |
| exact location in the archive. (The <i>fullpath</i> attribute can only be set for filesets that represent a single file. The <i>prefix</i> and <i>fullpath</i> attributes cannot both be set on the same fileset.) The <i>src</i> attribute |
| may be used in place of the <i>dir</i> attribute to specify a zip file whose |
| contents will be extracted and included in the archive. As with directories, include and exclude patterns may be used to specify a subset of the zip file |
| for inclusion in the archive.</p> |
| <h4>zipgroupfileset</h4> |
| <p>A <code><zipgroupfileset></code> allows for multiple zip files to be |
| merged into the archive. Each file found in this fileset is added to the archive |
| the same way that <i>zipfileset src</i> files are added.</p> |
| |
| |
| <h3>Examples</h3> |
| <pre> <zip destfile="${dist}/manual.zip" |
| basedir="htdocs/manual" |
| /></pre> |
| <p>zips all files in the <code>htdocs/manual</code> directory into a file called <code>manual.zip</code> |
| in the <code>${dist}</code> directory.</p> |
| <pre> <zip destfile="${dist}/manual.zip" |
| basedir="htdocs/manual" |
| update="true" |
| /></pre> |
| <p>zips all files in the <code>htdocs/manual</code> directory into a file called <code>manual.zip</code> |
| in the <code>${dist}</code> directory. If <code>manual.zip</code> |
| doesn't exist, it is created; otherwise it is updated with the |
| new/changed files.</p> |
| <pre> <zip destfile="${dist}/manual.zip" |
| basedir="htdocs/manual" |
| excludes="mydocs/**, **/todo.html" |
| /></pre> |
| <p>zips all files in the <code>htdocs/manual</code> directory. Files in the directory <code>mydocs</code>, |
| or files with the name <code>todo.html</code> are excluded.</p> |
| <pre> <zip destfile="${dist}/manual.zip" |
| basedir="htdocs/manual" |
| includes="api/**/*.html" |
| excludes="**/todo.html" |
| /></pre> |
| <p>zips all files in the <code>htdocs/manual</code> directory. Only html files under the directory <code>api</code> |
| are zipped, and files with the name <code>todo.html</code> are excluded.</p> |
| <pre> <zip destfile="${dist}/manual.zip"> |
| <fileset dir="htdocs/manual"/> |
| <fileset dir="." includes="ChangeLog.txt"/> |
| </zip></pre> |
| <p>zips all files in the <code>htdocs/manual</code> directory, and also adds the file <code>ChangeLog.txt</code> in the |
| current directory. <code>ChangeLog.txt</code> will be added to the top of the ZIP file, just as if |
| it had been located at <code>htdocs/manual/ChangeLog.txt</code>.</p> |
| <pre> <zip destfile="${dist}/manual.zip"> |
| <zipfileset dir="htdocs/manual" prefix="docs/user-guide"/> |
| <zipfileset dir="." includes="ChangeLog27.txt" fullpath="docs/ChangeLog.txt"/> |
| <zipfileset src="examples.zip" includes="**/*.html" prefix="docs/examples"/> |
| </zip></pre> |
| <p>zips all files in the <code>htdocs/manual</code> directory into the <code>docs/user-guide</code> directory |
| in the archive, adds the file <code>ChangeLog27.txt</code> in the |
| current directory as <code>docs/ChangeLog.txt</code>, and includes all the html files in <code>examples.zip</code> |
| under <code>docs/examples</code>. The archive might end up containing the files:</p> |
| <pre><code> docs/user-guide/html/index.html |
| docs/ChangeLog.txt |
| docs/examples/index.html |
| </code></pre> |
| <p> |
| The code |
| <pre> |
| <zip destfile="${dist}/manual.zip"> |
| <zipfileset dir="htdocs/manual" prefix="docs/user-guide"/> |
| <zipgroupfileset dir="." includes="examples*.zip"/> |
| </zip></pre> |
| </pre> |
| <p> |
| <p>zips all files in the <code>htdocs/manual</code> directory into the <code>docs/user-guide</code> directory in the archive and includes all the files in any file that maches <code>examples*.zip</code>, such as all files within <code>examples1.zip</code> or <code>examples_for_brian.zip</code>. |
