I want to obfuscate specific package some.specific.package for jar and their dependencies (before copying). Is there possible to do it?

Answer 1

did you try the command -keeppackagenames with negation (!) of the package you want to obfuscate? I tried teh following, with the result that just package org.neo4j.cineasts.domain was obfuscated. See below:

<configuration>
                <proguardVersion>4.8</proguardVersion>
                <obfuscate>true</obfuscate>
                <includeDependency>true</includeDependency>
                <injar>${project.artifactId}-${project.version}.jar</injar>
                <outjar>${project.artifactId}-${project.version}-obf.jar</outjar>
                <outputDirectory>${project.build.directory}</outputDirectory>
                <maxMemory>256m</maxMemory>
                <options>
                    <option>-keep public class org.neo4j.cineasts.controller.** { public *; public static *; }</option> 
                    <option>-keeppackagenames !org.neo4j.cineasts.domain</option>
                    <option>-allowaccessmodification</option>
                    <option>-dontskipnonpubliclibraryclasses</option>
                    <option>-dontskipnonpubliclibraryclassmembers</option>
                </options>
                <libs>
                    <lib>C:/devtools/Java/jdk1.6.0_29_64/jre/lib/rt.jar</lib>
                    <lib>C:/devtools/Java/jdk1.6.0_29_64/jre/lib/javaws.jar</lib>
                </libs>
            </configuration>
