Question

我想使用java混淆器来混淆我的源代码。我使用了proguard，因为它是最值得推荐的。我将build.xml配置为以下

<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>

但它会导致以下错误：

您应该尝试解决所获得的警告，而不是使用选项-ignorewarnings。你没有在你的问题中提到警告，但是你可能已经指定了依赖于程序类（带-injars）的库类（使用-libraryjars），这是不允许的。（CFR）。 ProGuard手册＆gt;引言
