You can use the bool target::has-executed(name) function inside of the
process-traces target instead of a dependency check.
Ie, the process-traces target would also contain a chain of 'call'
tasks, but each would contain this 'unless' test.
For example, inside process-traces, you'd have:
<call target="check-trends-dir" unless="${target::has-executed('check-
trends-dir')}"/>
you could wrap this in a custom task (callonce?) that essentially
performs:
<call target="${targetname}" unless="${target::has-
executed(targetname)}"/>
Hope that helps.
