iDempiere headless build does nothing

[johnbendi]

I get the following message when I run the following command

./buckminster -L DEBUG -consoleLog -data /opt/idempiere.local/ build -t

I get the following output:

My real confusion is how does buckminster commandline build work? In the root of idempiere there is nothing like a file that gives buckminster instruction as to how to build the idempiere workspace. What does that command actually intend to do. Can someone throw more light please?
