> Ant resolves the same dependencies multiple times if multiple targets are run 
> on the command line:
> "ant b c", where b and c both depend on a, results in a being executed twice. 
> However if you have a
> target d which depends on both b and c, "ant d" will only result in a being 
> executed once.
> say "ant jar compile-test" is run, this will currently fail as ivy-init is 
> run twice, resulting in the taskdef failing.
> Rather we need a guard on the ivy-init target itself to ensure it isn't run 
> twice.
> ie: put an unless attrib on ivy-init, then set that property in the body of 
> the target
