Tried with the ${session.executionRootDirectory} and got [ERROR] around
Ant part ...<untar
src="${session.executionRootDirectory}/.spark-dist/spark-1.6.1.tgz"
Sounds like maven-antrun-plugin (even last version) is not happy with
${session.executionRootDirectory}
Hacking maven-antrun-plugin or maven-download-plugin is not on my list. I
guess we can simply live with this for now.
