title: Obfuscate dependencies to single jar with Proguard
body: <p>I have modular maven application and "module1" depends on "module2" and "module2" depends on "module3" etc.. In module1 I have something like this:</p>
  
  <pre><code>&lt;profile&gt;
  &lt;id&gt;obfuscate&lt;/id&gt;
  &lt;build&gt;
      &lt;plugins&gt;
          &lt;plugin&gt;
              &lt;groupId&gt;com.pyx4me&lt;/groupId&gt;
              &lt;artifactId&gt;proguard-maven-plugin&lt;/artifactId&gt;
              &lt;executions&gt;
                  &lt;execution&gt;
                      &lt;phase&gt;package&lt;/phase&gt;
                      &lt;goals&gt;
                          &lt;goal&gt;proguard&lt;/goal&gt;
                      &lt;/goals&gt;
                  &lt;/execution&gt;
              &lt;/executions&gt;
              &lt;configuration&gt;
                  &lt;options&gt;
                      &lt;option&gt;-allowaccessmodification&lt;/option&gt;
                      &lt;option&gt;-keep public class com.test.Main { *; }&lt;/option&gt;
                  &lt;/options&gt;
                  &lt;libs&gt;
                      &lt;lib&gt;${java.home}/lib/rt.jar&lt;/lib&gt;
                  &lt;/libs&gt;
              &lt;/configuration&gt;
              &lt;dependencies&gt;
                  &lt;dependency&gt;
                      &lt;groupId&gt;net.sf.proguard&lt;/groupId&gt;
                      &lt;artifactId&gt;proguard&lt;/artifactId&gt;
                      &lt;version&gt;${proguard.version}&lt;/version&gt;
                  &lt;/dependency&gt;
              &lt;/dependencies&gt;
          &lt;/plugin&gt;
      &lt;/plugins&gt;
  &lt;/build&gt;
  </code></pre>

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