Attaching the Shaded Artifact

By default, the plugin will replace the project's main artifact with the shaded artifact. If both the original and the shaded artifact should be installed/deployed to the repository, one can configure the plugin to attach the shaded artifact as a secondary artifact:

<project>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>3.6.2</version>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>shade</goal>
            </goals>
            <configuration>
              <shadedArtifactAttached>true</shadedArtifactAttached>
              <shadedClassifierName>jackofall</shadedClassifierName> <!-- Any name that makes sense -->
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
  ...
</project>

The shaded artifact is distinguished from the main artifact by means of the additional classifier.
