1. 创建build.xml

<?xml version="1.0"?>
<project default="obfuscate" basedir=".">
    <property file="build.properties" />
    <taskdef resource="proguard/ant/task.properties"
             classpath="proguard/lib/proguard.jar" />
    <target name="obfuscate" depends="clean,init" description="Obfuscate compiled classes">
        <proguard>
          -libraryjars ${java.home}/lib/rt.jar
          -injars      bin
          -outjars     out
          -keep public class Main {
            public static void main(java.lang.String[]);
              }
        </proguard>
    </target>    
    <target name="clean" description="clean build">
        <delete dir="out" />
    </target>
    
    <target name="init" description="build init">
        <mkdir dir="out" />
    </target>
