Jib: Jib build is not packing files from assembly descriptor

[yadavnikhil]

Description

When running jib build, i've a assembly descriptor in pom.xml which adds additional dependencies needed for my application to run, but Jib build only copies built jar from target dir to basedir & ignores any additional files that is created by assembly. The same works fine without jib in docker build.
Ex.

<image>
    <name>myregistry:5000/imageName:1.0.0</name>
    <build>
        <from>jdk</from>
        <assembly>
            <mode>dir</mode>
            <basedir>/opt/application</basedir>
            <inline>
                <id>add-files</id>
                <fileSets>											
                    <fileSet>
                        <directory>${project.build.directory}/addJars</directory>
                        <includes>
                            <include>*.jar</include>
                        </includes>
                        <outputDirectory>lib</outputDirectory>
                    </fileSet>
                    <fileSet>
                        <directory>${project.build.directory}/conf</directory>
                        <includes>
                            <include>**.*</include>
                        </includes>
                        <outputDirectory>etc/conf</outputDirectory>
                    </fileSet>
                </fileSets>
            </inline>
        </assembly>								
    </build>
</image>

Above just packs my built fat jar to application dir, but files from addJar, conf.d are ignored.
May be we need the extraDirectories params support that core Jib supports which can add them appropriately to baseDir/outputDirectory path.
