Hi,
I am new to JBoss and Java EE and starded my learning by doing with Forge. The problem is that I would like to install the Picketlink module :

http://forge.jboss.org/addon/org.picketlink.tools.forge:picketlink-forge-addon

However the installation crashes with the following trace:

[workspace]$ addon-install-from-git --url https://github.com/picketlink/picketlink-forge-addon.git --coordinate org.picketlink.tools.forge:picketlink-forge-addon

Any idea how can I debug this or what have I done wrong?

Thanks in advance,
