Issue raised at sbt/sbt#7971.

Description

Sample project to illustrate an issue with log levels in commands. This project defines an sbt command logThenFail which makes 3 log entries using the logger state.log then throws a MessageOnlyException to fail the command.

Problem

Log entries created from a command does not seem to display correctly in warn or error levels.

• Logging made from state.log does not show up in any warn and error log levels.
• error log from throwing MessageOnlyException also does not show up in warn and error log levels.

This is confusing to users, especially in the case of throwing MessageOnlyException to fail the command and the build.

$ sbt logThenFail
[info] [launcher] getting org.scala-sbt sbt 1.10.9  (this may take some time)...
[info] welcome to sbt 1.10.9 (Eclipse Adoptium Java 17.0.13)

[error] Some errors

# expect the warnings and errors to show up but empty
$ sbt --warn logThenFail

# expect the errors to show up but empty
$ sbt --error logThenFail

This issue does not seem to happen on task as can be seen with the task doing the same thing logThenFailTask. When running the task, the log entries display at the appropriate log level.
