never mind.
I found the problem. I was duplicating the 'doLast' directive, by
accidentally using both the shorthand (<<) and the explicit keyword:
task complete(dependsOn: [prepareSetupStructure]) << {
doLast {
println 'build is complete!'
}
}
This seems to cause a ConcurrentModificationException,
which, while not being completely helpful, is probably perfectly
understandable.

sean
