In the file...
Line 31 <property name="wookie.root.dir" location="../../../../wookie/"/>
Assumes that there is a folder called 'wookie' 4 folders up.
Other users may not have checked out the code into a folder called wookie (I use 'ApacheWookie' for example)
Tthe only way I could get it to work was by altering the line to...
<property name="wookie.root.dir" location="../../../"/>
Which is where the folder is relative to the project root when checked out from svn (irrelevant of the root name).
Easy fix i know, but I dont want to commit changes if i have missed something.
