Description
<property name="hadoop.jar" location="${build.dir}/hadoop-${hadoop.version}-core.jar" /> where hadoop.version is defined in ${ivy.dir}/libraries.properties as hadoop.version=0.20.0.
Though <jar jarfile="${build.dir}/${final.name}core.jar" where <property name="final.name" value="${name}${version}"/>.
Means there is a hadoop-0.21.0-dev-core.jar builded though the assert-hadoop-jar-exists target looks for a hadoop-0.2.0-core.jar.
