Java:如何使用自定义 Ant build.xml 在 Jar 项目中集成 ProGuard [英] Java: How to integrate ProGuard in Jar Project using custom Ant build.xml

问题描述

我有一个简单的 java 项目，它引用了两 (2) 个库 jar 文件.想要集成 ProGuard.

I have simple java project which refers to two (2) library jar files. Want to integrate ProGuard.

这是我当前的 build.xml:

Here's my current build.xml:

<?xml version="1.0" ?>
<project name="Samples" default="dist" basedir=".">
    <!-- generate JAR START -->
    <description>Samples Library</description>
    <!-- Setting global properties for this build -->
    <property name="src" location="src" />
    <property name="bin" location="bin" />

    <target name="dist">
        <jar destfile="Samples.jar" basedir="bin/">
            <!-- Use ** to include the directory recursively -->
            <include name="com/samples/**" />
        </jar>
    </target>
</project>

推荐答案

我找到了几种集成它的方法，但这是最简单的方法.

I found several ways to integrate it but this is the simplest way to do it.

<?xml version="1.0" ?>
<project name="Samples" default="dist" basedir=".">
    <!-- generate JAR START -->
    <description>Samples Library</description>
    <!-- Setting global properties for this build -->
    <property name="src" location="src" />
    <property name="bin" location="bin" />

    <target name="dist">
        <jar destfile="Samples.jar" basedir="bin/">
            <!-- Use ** to include the directory recursively -->
            <include name="com/samples/**" />
        </jar>
    </target>
    <!-- generate JAR END -->

    <!-- The local.properties file is created and updated by the 'android'
         tool.
         It contains the path to the SDK. It should *NOT* be checked into
         Version Control Systems. -->
    <property file="local.properties" />

    <!-- The build.properties file can be created by you and is never touched
         by the 'android' tool. This is the place to change some of the
         default property values used by the Ant rules.
         Here are some properties you may want to change/update:

         source.dir
             The name of the source directory. Default is 'src'.
         out.dir
             The name of the output directory. Default is 'bin'.

         Properties related to the SDK location or the project target should
         be updated using the 'android' tool with the 'update' action.

         This file is an integral part of the build system for your
         application and should be checked into Version Control Systems.

         -->
    <property file="build.properties" />

    <!-- The default.properties file is created and updated by the 'android'
         tool, as well as ADT.
         This file is an integral part of the build system for your
         application and should be checked into Version Control Systems. -->
    <property file="default.properties" />

    <!-- Add Proguard Tasks -->
    <property name="proguard.jar" location="proguard/lib/proguard.jar" />

    <taskdef resource="proguard/ant/task.properties"
         classpath="${proguard.jar}" />
    <proguard configuration="proguard.cfg"/>

</project>

这是 proguard.cfg:

-injars       Samples.jar
-outjars      Samples-out.jar
-libraryjars  libs/android.jar
-printmapping out.map

-renamesourcefileattribute SourceFile
-keepattributes Exceptions,InnerClasses,Signature,Deprecated,
                SourceFile,LineNumberTable,*Annotation*,EnclosingMethod

-keep public class * {
    public protected *;
}

-keepclassmembernames class * {
    java.lang.Class class$(java.lang.String);
    java.lang.Class class$(java.lang.String, boolean);
}

-keepclasseswithmembernames class * {
    native <methods>;
}

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keepclassmembers class * implements java.io.Serializable {
    static final long serialVersionUID;
    private static final java.io.ObjectStreamField[] serialPersistentFields;
    private void writeObject(java.io.ObjectOutputStream);
    private void readObject(java.io.ObjectInputStream);
    java.lang.Object writeReplace();
    java.lang.Object readResolve();
}
