How to make Redline RPM Library work with Ant?

Question

I use Ant as a build tool, I put this line into my Ant script at the very beginning:

<taskdef name="pure-java-rpm" classname="org.redline_rpm.ant.RedlineTask" classpath="lib/ant/redline-1.1.16.jar" />

I call it further:

<pure-java-rpm group="Games" name="${project-unix-name}" version="0" destination="${destdir}">
        <zipfileset prefix="/usr/share/games/${project-unix-name}" file="${destdir}/${game-jar-filename}"/>
        <depends name="java" version=">= 1.7"/>
    </pure-java-rpm>

I get the following error message: BUILD FAILED /home/gouessej/Documents/programmation/java/workspace/tuer/build.xml:445: java.lang.NoClassDefFoundError: org/apache/commons/compress/compressors/bzip2/BZip2CompressorInputStream

However, Apache Commons Compress isn't mentioned, it doesn't seem to be a dependency of this library according to the "usage" page. Do I really have to add Apache Commons Compress into the classpath of this task definition to make it work? Is there another solution?

The instructions don't mention the dependencies, you need at least SLF4J, Bountycastle, XZ and Apache Commons Compress to use Redline RPM. I've just modified my task definition:

<taskdef name="pure-java-rpm" classname="org.redline_rpm.ant.RedlineTask">
    <classpath>
        <pathelement path="bcpg-jdk15on-151.jar"/>
        <pathelement path="commons-compress-1.8.1.jar"/>
        <pathelement path="slf4j-api-1.7.7.jar"/>
        <pathelement path="slf4j-simple-1.7.7.jar"/>
        <pathelement path="xz-1.4.jar"/>
        <pathelement path="redline-1.1.16.jar"/>
    </classpath>
</taskdef>

You can find those JARs here:
