[ http://issues.apache.org/jira/browse/JELLY-201?page=comments#action_59199 ] Nacho G. Mac Dowell commented on JELLY-201: -------------------------------------------
Hi, what I was looking for is the negative version of util:available. If ant:available exists, maybe util:available is not recommended? The util:available tag accepts a file and an uri. I suppose the ant:available doesn't provide the same functionality? The thing is that there are quite a few places I've seen where mkdir gets called regardless if the directory exists. While the overhead is not a problem, I think that it would improve readability of jelly scripts.
