11<h2>Ant Task</h2>
12
13<b>ProGuard</b> can be run as a task in the Java-based build tool Ant (version
141.6.0 or higher).
15<p>
16
17Before you can use the <code>proguard</code> task, you have to tell Ant about
18this new task. The easiest way is to add the following line to your
19<code>build.xml</code> file:
20<p>
21
22<pre>
23&lt;taskdef resource="proguard/ant/task.properties"
24         classpath="/usr/local/java/proguard/lib/proguard.jar" /&gt;
25</pre>
26<p>
27
28Please make sure the class path is set correctly for your system.
29<p>
30
31There are three ways to configure the ProGuard task: using an external
32configuration file, using embedded ProGuard configuration options, or using
33the equivalent XML configuration tags. These three ways can be combined,
34depending on practical circumstances and personal preference.
35<p>
36
37<h3>1. An external ProGuard configuration file</h3>
38
39The simplest way to use the ProGuard task in an Ant build file is to keep your
40ProGuard configuration file, and include it from Ant. You can include your
41ProGuard configuration file by setting
42the <a href="#configuration_attribute"><code>configuration</code></a>
43attribute of your
44<code>proguard</code> task. Your ant build file will then look like this:
45<p>
46
47<pre>
48&lt;taskdef resource="proguard/ant/task.properties"
49         classpath="/usr/local/java/proguard/lib/proguard.jar" /&gt;
50&lt;proguard configuration="myconfigfile.pro"/&gt;
51</pre>
52<p>
53
54This is a convenient option if you prefer ProGuard's configuration style over
55XML, if you want to keep your build file small, or if you have to share your
56configuration with developers who don't use Ant.
57<p>
58
59<h3>2. Embedded ProGuard configuration options</h3>
60
61Instead of keeping an external ProGuard configuration file, you can also copy
62the contents of the file into the nested text of the <code>proguard</code> task
63(the PCDATA area). Your Ant build file will then look like this:
64<p>
65
66<pre>
67&lt;taskdef resource="proguard/ant/task.properties"
68         classpath="/usr/local/java/proguard/lib/proguard.jar" /&gt;
69&lt;proguard&gt;
70  -libraryjars ${java.home}/lib/rt.jar
71  -injars      in.jar
72  -outjars     out.jar
73
74  -keepclasseswithmembers public class * {
75      public static void main(java.lang.String[]);
76  }
77&lt;/proguard&gt;
78</pre>
79<p>
80
81Some minor syntactical changes are required in order to conform with the XML
82standard.
83<p>
84
85Firstly, the <code>#</code> character cannot be used for comments in an XML
86file. Comments must be enclosed by an opening <code>&lt;!--</code> and a
87closing <code>--&gt;</code>. All occurrences of the <code>#</code> character
88can be removed.
89<p>
90
91Secondly, the use of <code>&lt;</code> and <code>&gt;</code> characters would
92upset the structure of the XML build file. Environment variables are now
93enclosed by an opening <code>${</code> and a closing <code>}</code>. This
94syntax also allows you to use Ant properties within the ProGuard
95configuration. Other occurrences of <code>&lt;</code> and <code>&gt;</code>
96have to be encoded as <code>&amp;lt;</code> and <code>&amp;gt;</code>.
97<p>
98
99<h3>3. XML configuration tags</h3>
100
101If you really prefer a full-blown XML configuration, you can replace the
102ProGuard configuration options by XML configuration tags. The resulting
103configuration will be equivalent, but much more verbose and difficult to read,
104as XML goes. The remainder of this page presents the supported tags. For a
105more extensive discussion of their meaning, please consult the traditional <a
106href="usage.html">Usage</a> section. You can find some sample configuration
107files in the <code>examples/ant</code> directory of the ProGuard distribution.

111<h2>Task Attributes and Nested Elements</h2>
112
113The <code><b>&lt;proguard&gt;</b></code> task and the
114<code><b>&lt;proguardconfiguration&gt;</b></code> task can have the following
115attributes (only for <code>&lt;proguard&gt;</code>) and nested
116elements:
117
118<dl>

452<h2>Class Path Attributes and Nested Elements</h2>
453
454The jar tags are path tags, so they can have any of the path attributes (or
455nested elements). The most common attributes are:
456
457<dl>
458
459<dt><code><b>path</b></code> = "<i>path</i>"</dt>
460<dd>The names of the jars (or wars, ears, zips, or directories), separated by
461    the path separator.</dd>
462
463<dt><code><b>location</b></code> = "<i>name</i>" (or <code><b>file</b></code>
464    = "<i>name</i>", or <code><b>dir</b></code> = "<i>name</i>", or
465    <code><b>name</b></code> = "<i>name</i>")</dt>
466<dd>Alternatively, the name of a single jar (or war, ear, zip, or
467    directory).</dd>
468
469<dt><code><b>refid</b></code> = "<i>ref_id</i>"</dt>
470<dd>Alternatively, a reference to the path or file set with the attribute
471    <code>id</code> = "<i>ref_id</i>".</dd>
472
473</dl>
474
475In addition, the jar tags can have ProGuard-style filter attributes:
476
477<dl>
478
479<dt><code><b>filter</b></code> =
480    "<a href="usage.html#filefilters"><i>file_filter</i></a>"</dt>
481<dd>An optional filter for all class file names and resource file names that
482    are encountered.</dd>
483
484<dt><code><b>jarfilter</b></code> =
485    "<a href="usage.html#filefilters"><i>file_filter</i></a>"</dt>
486<dd>An optional filter for all jar names that are encountered.</dd>
487
488<dt><code><b>warfilter</b></code> =
489    "<a href="usage.html#filefilters"><i>file_filter</i></a>"</dt>
490<dd>An optional filter for all war names that are encountered.</dd>
491
492<dt><code><b>earfilter</b></code> =
493    "<a href="usage.html#filefilters"><i>file_filter</i></a>"</dt>
494<dd>An optional filter for all ear names that are encountered.</dd>
495
496<dt><code><b>zipfilter</b></code> =
497    "<a href="usage.html#filefilters"><i>file_filter</i></a>"</dt>
498<dd>An optional filter for all zip names that are encountered.</dd>
499
500</dl>

503<h2>Keep Modifier Attributes</h2>
504
505The keep tags can have the following <i>modifier</i> attributes:
506
507<dl>
508
509<dt><a href="usage.html#allowshrinking"><code><b>allowshrinking</b></code></a>
510    = "<i>boolean</i>"
511    (default = false)</dt>
512<dd>Specifies whether the entry points specified in the keep tag may be

532The keep tags can have the following <i>class_specification</i> attributes and
533<i>class_member_specifications</i> nested elements:
534
535<dl>
536
537<dt><code><b>access</b></code> = "<i>access_modifiers</i>"</dt>
