[rules-users] droolsjbpm-build-bootstrap script is broken ?

Hi, I want to investigate why I couldn't build my system using the latest snapshot of jbpm and drools.. So, I cloned the git@github.com:droolsjbpm/droolsjbpm-build-bootstrap.git repository and I'm following the readme.md file. When I try $ droolsjbpm-build-bootstrap/script/git-clone-others.sh, I'm getting a error: =============================================================================== This directory already exists: droolsjbpm-build-bootstrap =============================================================================== =============================================================================== Repository: droolsjbpm-knowledge =============================================================================== Too many arguments. usage: git clone [options] [--] <repo> [<dir>] -v, --verbose be more verbose -q, --quiet be more quiet Am I missing something or the script is broken ? regards, Cristiano
