如何将 SBT 默认日志级别设置为“警告”？

Question

default SBT log level is info (see http://code.google.com/p/simple-build-tool/wiki/RunningSbt ).

How do I set it to warn as the default?

@Christian: Thanks? Did you get that to work. I modified the sbt.boot:properties accordingly and passed it via:

(1) -Dsbt.boot.properties=mysbt.boot.properties

(2) -jar /usr/local/Cellar/sbt/0.7.7/libexec/sbt-launch-0.7.7.jar "@/usr/local/Cellar/sbt/0.7.7/libexec/mysbt.boot.properties"

Both ways process my sbt.boot.properties but I still see [info] log messages. Overriding project settings does not work either.

I wonder if this works at all. I even found a bug .

Thanks, Lars

Answer 1

You can set it temporarily by prefixing your action with warn , eg

~> sbt warn compile

or from the sbt console:

~> sbt
[info] Building project test 1.0 against Scala 2.8.1
[info]    using TestProject with sbt 0.7.7 and Scala 2.7.7
> warn
Set log level to warn
> compile

In XSBT this seems to be the way to do it from the console

set logLevel in run := Level.Debug

Note that these are SBT levels, so for example they don't work directly with Play 2.0!

You could define it in sbt.boot.properties as explained here: sbt wiki
