We'd need a command-line option to override this, and it also seems

We could use system properties for this as you can also set system
properties in your gradle.properties file. You want to specify for
file logging (none, info, debug) I guess.
My current idea is to have three log levels (HIGH_LEVEL, INFO, DEBUG)
and two appenders (console and file).
The default would be: HIGH_LEVEL/INFO
The criteria for HIGH_LEVEL is: Should only indicate progress and
which tasks are executed. By being not verbose it does not hide
warnings/unusual things (like our very verbose output does now).
INFO: Used by the user to figure out why the build has failed. Should
offer enough information to find the reason in the most cases.
DEBUG: Used by Gradle developers to learn about the internal Gradle
behavior. Used rarely by the users to figure out problems.
What do you think?
I think this is good. Are there warning and error levels too? Are they
always shown? What would we do for the -q option?
Something I'd like is the ability to control from the command-line
the logging levels for broad functional areas, such as the projects,
ant, ivy, groovy and gradle itself. We have this for ivy already, it
would be nice to generalise this a bit. For example, gradle -d ivy -d
ant would enable debug level for all ivy and ant logging. Or gradle
-d projects would enable debug level for my project's logging.
This is funny. I was thinking in the opposite direction and removing
this special Ivy switch. My motivation has been to simplify things for
our users. But looking at your proposal we can have both worlds. Just
using -d will enable debug for everything, -d <area> only for a
subsystem. Right now -i is used for making Ivy output silent. This
will be no longer necessary with our high level logging. My idea is to
use the -i option the same way we plan to use the -d option, but for
the info level.
Possibly the -q option could work the same way too.
