eclipse proguard maven project configuration - java obfuscate

I am going to describe how can can configure proguard and maven to obfuscate a java project. If you need help on how to configure maven project in eclipse see my earlier post.

A)Project configs

    <!-- Project configs -->
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.gt</groupId>
    <artifactId>maven-proguard-test</artifactId>
    <packaging>jar</packaging>
    <version>-ver.01</version>
    <name>maven-proguard-test-application</name>

    <properties>
        <project.build.mainClass>com.gt.App</project.build.mainClass>
    </properties>

B) Proguard Configuration in pom.xml :

            <!-- Proguard configs -->
            <plugin>
                <groupId>com.pyx4me</groupId>
                <artifactId>proguard-maven-plugin</artifactId>
                <version>2.0.4</version>

                <!-- run proguard at package phase -->
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>proguard</goal>
                        </goals>
                    </execution>
                </executions>

                <configuration>
                    <obfuscate>true</obfuscate>
                    <archive>
                        <manifest>
                            <mainClass>${project.build.mainClass}</mainClass>
                        </manifest>
                    </archive>
                    <options>
                        <option>-allowaccessmodification</option>
                        <option>-dontshrink</option>
                        <option>-keepattributes *Annotation*</option>
                        <option>-keep public class ${project.build.mainClass} { *; }</option>
                        <!-- <option>-keep public class [com.qualified_name]</option> -->

                        <!-- if you want to keep enum classes, this is generally expected -->
                        <option>-keep public enum * { *;}</option>
                    </options>
                    <outjar>${project.build.finalName}.jar</outjar>
                    <libs>
                        <lib>${java.home}/lib/rt.jar</lib>
                        <lib>${java.home}/lib/jsse.jar</lib>
                        <lib>${java.home}/lib/jce.jar</lib>
                    </libs>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>net.sf.proguard</groupId>
                        <artifactId>proguard</artifactId>
                        <version>4.4</version>
                        <scope>runtime</scope>
                    </dependency>
                </dependencies>
            </plugin>

C)Maven jar plugin to make .jar file

            <!-- making jar file -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <configuration>
                    <archive>
                        <manifest>
                            <mainClass>${project.build.mainClass}</mainClass>
                        </manifest>
                    </archive>
                </configuration>
            </plugin>

D)Maven dependency plugin - copy jar dependencies

            <!-- maven dependency plugin to copy all dependency jar to a folder, here 
                copying to target/lib -->
            <plugin>
                <artifactId>maven-dependency-plugin</artifactId>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>copy-dependencies</goal>
                        </goals>
                        <configuration>
                            <outputDirectory>target/lib</outputDirectory>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

E)run.bat file to run the jar file ( it loads the jar files in classpath) You need to copy run.jar file to target folder. com.gt.App  is my main class.

@echo off
Start "" /B javaw -Xmx256M -cp "maven-proguard-test-0.0.1-SNAPSHOT.jar;lib/*" com.gt.App

F)Build command : mvn clean compile package
