示例：<taskdef resource="proguard/ant/task.properties"
classpath="/usr/local/java/proguard/lib/proguard.jar" />
<target name="proguard"> <proguard configuration="myconfigfile.pro"/></target>可以将proguard想象成自定义的命令标签，和jar、javac、copy等命令一样
ProGuard can be run as a task in the Java-based build tool Ant (version 1.8 or higher).
Before you can use the proguard task, you have to tell Ant about this new task. The easiest way is to add the following line to your build.xml file:
<taskdef resource="proguard/ant/task.properties"
classpath="/usr/local/java/proguard/lib/proguard.jar" />
Please make sure the class path is set correctly for your system.
There are three ways to configure the ProGuard task:
These three ways can be combined, depending on practical circumstances and personal preference.
1. An external ProGuard configuration file The simplest way to use the ProGuard task in an Ant build file is to keep your ProGuard configuration file, and include it from Ant. You can include your ProGuard configuration file by setting the configuration attribute of your proguard task. Your ant build file will then look like this:
<taskdef resource="proguard/ant/task.properties"
classpath="/usr/local/java/proguard/lib/proguard.jar" />
<proguard configuration="myconfigfile.pro"/>
This is a convenient option if you prefer ProGuard‘s configuration style over XML, if you want to keep your build file small, or if you have to share your configuration with developers who don‘t use Ant.
2. Embedded ProGuard configuration options Instead of keeping an external ProGuard configuration file, you can also copy the contents of the file into the nested text of the proguard task (the PCDATA area). Your Ant build file will then look like this:
<taskdef resource="proguard/ant/task.properties"
classpath="/usr/local/java/proguard/lib/proguard.jar" />
<proguard>
-libraryjars ${java.home}/lib/rt.jar
-injars in.jar
-outjars out.jar
-keepclasseswithmembers public class * {
public static void main(java.lang.String[]);
}
</proguard>
Some minor syntactical changes are required in order to conform with the XML standard.
Firstly, the # character cannot be used for comments in an XML file. Comments must be enclosed by an opening <!-- and a closing -->. All occurrences of the # character can be removed.
Secondly, the use of < and > characters would upset the structure of the XML build file. Environment variables can be specified with the usual Ant style ${...}, instead of the ProGuard style <...>. Other occurrences of < and > have to be encoded as < and > respectively.
3. XML configuration tags If you really prefer a full-blown XML configuration, you can replace the ProGuard configuration options by XML configuration tags. The resulting configuration will be equivalent, but much more verbose and difficult to read, as XML goes. The remainder of this page presents the supported tags. For a more extensive discussion of their meaning, please consult the traditional Usage section. You can find some sample configuration files in the examples/ant directory of the ProGuard distribution.
The <proguard> task and the <proguardconfiguration> task can have the following attributes (only for <proguard>) and nested elements:
