Obfuscate dependencies to single jar with Proguard

问题

I have modular maven application and "module1" depends on "module2" and "module2" depends on "module3" etc.. In module1 I have something like this:

<profile>
<id>obfuscate</id>
<build>
    <plugins>
        <plugin>
            <groupId>com.pyx4me</groupId>
            <artifactId>proguard-maven-plugin</artifactId>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>proguard</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <options>
                    <option>-allowaccessmodification</option>
                    <option>-keep public class com.test.Main { *; }</option>
                </options>
                <libs>
                    <lib>${java.home}/lib/rt.jar</lib>
                </libs>
            </configuration>
            <dependencies>
                <dependency>
                    <groupId>net.sf.proguard</groupId>
                    <artifactId>proguard</artifactId>
                    <version>${proguard.version}</version>
                </dependency>
            </dependencies>
        </plugin>
    </plugins>
</build>

This creates successfully obfuscated "module1". I want to create single jar with all obfuscated dependencies (obfuscated module1 and module2 etc.). Is it possible?

回答1:

Maven Shade Plugin

This plugin provides the capability to package the artifact in an uber-jar, including its dependencies and to shade - i.e. rename - the packages of some of the dependencies.

Check it out here.

回答2:

Try the <assembly> option of the maven-proguard-plugin. Make references to each of the dependencies you wanted bundled into the obfuscated jar. See examples.

If you want package dependency jars into your uber jar, use shade plugin! here's an example:

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>1.4</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <transformers>
                            <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"/>
                        </transformers>
                    </configuration>
                </execution>
            </executions>
        </plugin>
