If you'd rather not use a test build version, there is a special custom option on the "Action Inspector" tab called "Extra Params at End". You should be able to add the "-logging " option there in the current version.
I don't find the "Action Inspector" tab with the special custom option "Extra Params at End". I have only the Tabs "General", "Runtime" and "Ant Options" when I look at the ANT action.
Do you plan to fix this in Version 4.x too? Most of our scripts ran with 4.x this time.
The “Action Inspector” tab isn’t part of the Ant Project action, it’s in the top left pane of the main window. There are three tabs there, “Project”, “Action Types”, and “Action Inspector”. I had to look around a bit for it, too.
