Hey,

You can't just use Property('got_revision'), you need a context where asking 
for 'got_revision' actually makes sense.

You can call myobj.getProperty('got_revision') on any instance of classes 
which inherit from the IProperties interface. This can be for example a 
BuildStatus or BuildStep instance. See [1] for an extensive overview + 
examples.

Or just google for "getproperty got_revision" to get some example uses.
