| 11 | <h2><a name="zip">Zip</a></h2>
|
|---|
| 12 | <h3>Description</h3>
|
|---|
| 13 | <p>Creates a zipfile.</p>
|
|---|
| 14 | <p>The <i>basedir</i> attribute is the reference directory from where to zip.</p>
|
|---|
| 15 | <p>Note that file permissions will not be stored in the resulting zipfile.</p>
|
|---|
| 16 | <p>It is possible to refine the set of files that are being zipped. This can be
|
|---|
| 17 | done with the <i>includes</i>, <i>includesfile</i>, <i>excludes</i>, <i>excludesfile</i> and <i>defaultexcludes</i>
|
|---|
| 18 | attributes. With the <i>includes</i> or <i>includesfile</i> attribute you specify the files you want to
|
|---|
| 19 | have included by using patterns. The <i>exclude</i> or <i>excludesfile</i> attribute is used to specify
|
|---|
| 20 | the files you want to have excluded. This is also done with patterns. And
|
|---|
| 21 | finally with the <i>defaultexcludes</i> attribute, you can specify whether you
|
|---|
| 22 | want to use default exclusions or not. See the section on <a
|
|---|
| 23 | href="../dirtasks.html#directorybasedtasks">directory based tasks</a>, on how the
|
|---|
| 24 | inclusion/exclusion of files works, and how to write patterns. </p>
|
|---|
| 25 | <p>This task forms an implicit <a href="../CoreTypes/fileset.html">FileSet</a> and
|
|---|
| 26 | supports all attributes of <code><fileset></code>
|
|---|
| 27 | (<code>dir</code> becomes <code>basedir</code>) as well as the nested
|
|---|
| 28 | <code><include></code>, <code><exclude></code> and
|
|---|
| 29 | <code><patternset></code> elements.</p>
|
|---|
| 30 | <p>Or, you may place within it nested file sets, or references to file sets.
|
|---|
| 31 | In this case <code>basedir</code> is optional; the implicit file set is <i>only used</i>
|
|---|
| 32 | if <code>basedir</code> is set. You may use any mixture of the implicit file set
|
|---|
| 33 | (with <code>basedir</code> set, and optional attributes like <code>includes</code>
|
|---|
| 34 | and optional subelements like <code><include></code>); explicit nested
|
|---|
| 35 | <code><fileset></code> elements so long as at least one fileset total is specified. The ZIP file will
|
|---|
| 36 | 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>
|
|---|
| 37 | <p>The Zip task also supports the merging of multiple zip files into the zip file.
|
|---|
| 38 | This is possible through either the <i>src</i> attribute of any nested filesets
|
|---|
| 39 | or by using the special nested fileset <i>zipgroupfileset</i>.</p>
|
|---|
| 40 |
|
|---|
| 41 | <p>The <code>update</code> parameter controls what happens if the ZIP
|
|---|
| 42 | file already exists. When set to <code>yes</code>, the ZIP file is
|
|---|
| 43 | updated with the files specified. (New files are added; old files are
|
|---|
| 44 | replaced with the new versions.) When set to <code>no</code> (the
|
|---|
| 45 | default) the ZIP file is overwritten if any of the files that would be
|
|---|
| 46 | added to the archive are newer than the entries inside the archive.
|
|---|
| 47 | Please note that ZIP files store file modification times with a
|
|---|
| 48 | granularity of two seconds. If a file is less than two seconds newer
|
|---|
| 49 | than the entry in the archive, Ant will not consider it newer.</p>
|
|---|
| 50 |
|
|---|
| 51 | <p>The <code>whenempty</code> parameter controls what happens when no files match.
|
|---|
| 52 | If <code>skip</code> (the default), the ZIP is not created and a warning is issued.
|
|---|
| 53 | If <code>fail</code>, the ZIP is not created and the build is halted with an error.
|
|---|
| 54 | If <code>create</code>, an empty ZIP file (explicitly zero entries) is created,
|
|---|
| 55 | which should be recognized as such by compliant ZIP manipulation tools.</p>
|
|---|
| 56 | <p>This task will now use the platform's default character encoding
|
|---|
| 57 | for filenames - this is consistent with the command line ZIP tools,
|
|---|
| 58 | but causes problems if you try to open them from within Java and your
|
|---|
| 59 | filenames contain non US-ASCII characters. Use the encoding attribute
|
|---|
| 60 | and set it to UTF8 to create zip files that can safely be read by
|
|---|
| 61 | Java.</p>
|
|---|
| 62 |
|
|---|
| 63 | <p>Starting with Ant 1.5.2, <code><zip></code> can store Unix permissions
|
|---|
| 64 | inside the archive (see description of the filemode and dirmode
|
|---|
| 65 | attributes for <a href="../CoreTypes/zipfileset.html"><zipfileset></a>).
|
|---|
| 66 | Unfortunately there is no portable way to store these permissions.
|
|---|
| 67 | Ant uses the algorithm used by <a href="http://www.info-zip.org">Info-Zip's</a>
|
|---|
| 68 | implementation of the zip and unzip commands - these are the default
|
|---|
| 69 | versions of zip and unzip for many Unix and Unix-like systems.</p>
|
|---|
| 70 |
|
|---|
| 71 | <p><b>Please note that the zip format allows multiple files of the same
|
|---|
| 72 | fully-qualified name to exist within a single archive. This has been
|
|---|
| 73 | documented as causing various problems for unsuspecting users. If you wish
|
|---|
| 74 | to avoid this behavior you must set the <code>duplicate</code> attribute
|
|---|
| 75 | to a value other than its default, <code>"add"</code>.</b></p>

|
|---|
| 195 | <h4>fileset</h4>
|
|---|
| 196 | <p>The zip task supports any number of nested <a
|
|---|
| 197 | href="../CoreTypes/fileset.html"><code><fileset></code></a> elements to specify
|
|---|
| 198 | the files to be included in the archive.</p>
|
|---|
| 199 |
|
|---|
| 200 | <h4>zipfileset</h4>
|
|---|
| 201 |
|
|---|
| 202 | <p>The zip task supports any number of nested <a
|
|---|

|
|---|
| 205 |
|
|---|
| 206 | <h4>zipgroupfileset</h4>
|
|---|
| 207 | <p>A <code><zipgroupfileset></code> allows for multiple zip files to be
|
|---|
| 208 | merged into the archive. Each file found in this fileset is added to the archive
|

| 209 | the same way that <i>zipfileset src</i> files are added.</p>

|---|
| 253 | current directory as <code>docs/ChangeLog.txt</code>, and includes all the html files in <code>examples.zip</code>
|
