谁给介绍一款好的混淆器，最好要能在ant中使用的，谢谢
我在sourceforge上找着了一款
  <target name="obfuscate" depends="jar">
    <taskdef name="proguard" classname="proguard.ant.ProGuardTask" classpath="${required.lib}/proguard.jar" description="sourceforge.net" />
    
    <proguard printseeds="on">
      <libraryjar refid="required.lib.set" />
      <libraryjar name="${java.home}/lib/rt.jar" />
      <keep type="interface" />
      <injar>
        <fileset dir="${build.lib}">
          <include name="*.jar" />
        </fileset>
      </injar>
      <outjar name="${reports.tests}" />
    </proguard>
  </target>
=============================================

可是在nmi的反编译下无所遁形
