I am working on a java application using maven architecture project in Eclipse IDE and java 7
I need to generated an obfuscated a jar file which also must include all the dependencies obfuscated in it I've been checking some solutions around but I´ve been unable to get the desired result.
Some of the places that I've checked are this:
from the two first links I based most of my current implementation
this is my pom.xml file:

the error I'm getting is the following:
[ERROR] Failed to execute goal com.pyx4me:proguard-maven-plugin:2.0.4:proguard (default) on project CacheClienteModelC: Can't rename E:\Users\B267481\Documents\ServidorDesarroCreditoAcertum\CacheClienteModelC\target\CacheClienteModelC.jar -> [Help 1]
Just to make things more clear When I build the project, two diferent jars are generated at the target folder (CacheClienteModelC-jar-with-dependecies.jar and CacheClienteModelC.jar), the file that I try to generate is CacheClienteModelC-small.jar (obfuscated jar) which is never created.
How should I configure the plugin to obfuscate my project's file?
You're using an older version of the proguard plugin for Maven, you should use this one, you can find it in the Maven Central repository.
Now as for your pom.xml, remove from the dependencies the com.pyx4me dependency, you won't need it there.
Now as for the plugin configuration try with something like this:
<plugin>
<groupId>com.github.wvengen</groupId>
<artifactId>proguard-maven-plugin</artifactId>
<version>2.0.10</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>proguard</goal>
</goals>
</execution>
</executions>
<configuration>
<obfuscate>true</obfuscate>
<injar>${project.build.finalName}.jar</injar>
<outjar>${project.build.finalName}-small.jar</outjar>
<includeDependency>true</includeDependency>
<options>
<option>-keep public class your.package.Main { *; }</option>
</options>
<libs>
<lib>${java.home}/lib/rt.jar</lib>
<lib>${java.home}/lib/jce.jar</lib>
</libs>
<archive>
<manifest>
<mainClass>Main</mainClass>
<packageName>your.package</packageName>
</manifest>
</archive>
</configuration>
<dependencies>
<dependency>
<groupId>net.sf.proguard</groupId>
<artifactId>proguard-base</artifactId>
<version>4.10</version>
<scope>runtime</scope>
</dependency>
</dependencies>
</plugin>
See how you specify the dependency for proguard in it? That should generate the obfuscated jar without problem. Try it out.
