Log

Task.log is the default logger provided for every task. While your task is running, System.out and System.in are also redirected to this logger. The logs for a task are streamed to standard out/error as you would expect, but each task's specific output is also streamed to a log file on disk, e.g. out/run.log or out/classFiles.log for you to inspect later.

Messages logged with log.debug appear by default only in the log files. You can use the --debug option when running mill to show them on the console too.
