使用proguard混淆源代碼

我想使用java混淆器來混淆我的源代碼。我使用了proguard，因爲它是建議最多的一個。我配置了我的build.xml如下使用proguard混淆源代碼

<target name="-post-jar"> 
    <property name="proguard.jar.path" value="D:/pro/proguard.jar" /> 
    <taskdef resource="proguard/ant/task.properties" 
      classpath="${proguard.jar.path}" /> 
    <echo message="Obfuscating ${dist.jar}..."/> 
    <mkdir dir="${build.dir}/obfuscated"/> 
    <proguard printmapping="${build.dir}/obfuscated/${application.title}.map" 
       renamesourcefileattribute="SourceFile" ignorewarnings="true"> 

     <injar file="${dist.jar}" /> 
     <outjar file="${build.dir}/obfuscated/${application.title}.jar" /> 

     <libraryjar path="${javac.classpath}" />   
     <libraryjar file="${java.home}/lib/rt.jar" /> 
     <libraryjar file="${java.home}/lib/jce.jar" /> 

     <keepattribute name="InnerClasses" /> 
     <keepattribute name="SourceFile" /> 
     <keepattribute name="LineNumberTable" /> 
     <keepattribute name="Deprecated" /> 
     <keepattribute name="*Annotation*" /> 
     <keepattribute name="Signature" /> 
     <keepattribute name="Exceptions" /> 

     <keep access="public"> 
      <field access="public protected" /> 
      <method access="public protected" /> 
     </keep> 

     <keepclassmembernames access="public"> 
      <method type  ="java.lang.Class" 
        name  ="class$" 
        parameters="java.lang.String" /> 
      <method type  ="java.lang.Class" 
        name  ="class$" 
        parameters="java.lang.String,boolean" /> 
     </keepclassmembernames> 

     <keepclasseswithmembernames> 
      <method access="native" /> 
     </keepclasseswithmembernames> 

     <keepclassmembers extends="java.lang.Enum"> 
      <method access="public static" 
        type="**[]" 
        name="values" 
        parameters="" /> 
      <method access="public static" 
        type="**" 
        name="valueOf" 
        parameters="java.lang.String" /> 
     </keepclassmembers> 

     <keepnames implements="java.io.Serializable"/> 
     <keepclassmembers implements="java.io.Serializable"> 
      <field access ="final" 
        type  ="long" 
        name  ="serialVersionUID" /> 
      <field access ="!static !transient" 
        name  ="**"/> 
      <field access ="!private" 
        name  ="**"/> 
      <method access ="!private" 
        name  ="**"/> 
      <method access ="private" 
        type  ="void" 
        name  ="writeObject" 
        parameters="java.io.ObjectOutputStream" /> 
      <method access ="private" 
        type  ="void" 
        name  ="readObject" 
        parameters="java.io.ObjectOutputStream" /> 
      <method type  ="java.lang.Object" 
        name  ="writeReplace" 
        parameters="" /> 
      <method type  ="java.lang.Object" 
        name  ="readResolve" 
        parameters="" /> 
     </keepclassmembers> 

    </proguard> 
    <copy file="${build.dir}/obfuscated/${application.title}.jar" tofile="${dist.jar}" overwrite="true"/> 
    <delete dir="${build.dir}/obfuscated"/> 
</target>

但它會導致以下錯誤：

@AndrewThompson這是一個選擇，爲什麼不呢？ – 2013-05-14 07:14:13

看看這個鏈接是否可以幫助你：http://sourceforge.net/p/proguard/bugs/384/ – 2013-05-14 07:17:11

@Andrew Thompson：在我的情況下必須至少保護它免於反編譯。 – Deeps 2013-05-14 07:31:14

而不是使用選項-ignorewarnings的，你應該嘗試解決您獲得的警告。你沒有在你的問題中提到警告，但可能是你已經指定了依賴於程序類（帶有-injars）的庫類（帶有-libraryjars），這是不允許的。（CFR）。 ProGuard手冊>簡介。
