hi,

I have download: "Drools Examples" on http://www.jboss.org/drools/downloads
I use eclipse in order to build.
I have follow this:
https://github.com/droolsjbpm/droolsjbpm-build-bootstrap/blob/master/README.md
in order to configure eclipse.

I don't know what i must do.

After one build i got this:
