Thanks, Dominique. You stated this quite clearly.
It seems that, since the project knows all its listeners to notify them of
an event, it wouldn't be so hard to add a method to query all the listeners
for their log level and then return the max of that. The build listeners
would also need a getter for their log level. I will allow that, by this
time, you're having to do a certain amount of work to spare yourself some
other work. And I'll also allow that the work you're being spared is
typically a negligible burden.
There's one other matter I want to investigate when it comes to logging. I
may want my Ant task to consume some component that wasn't written for Ant,
so it doesn't have a handle on the Project or a ProjectComponent to log
anything. Perhaps it uses log4j. I'd like to see to what extent Ant's
logging can coordinate with and control the Ant-agnostic logging.
Not a question so much as thinking out loud.
