We have to look into the reason why the shaded version of the compiler
plugin reports the following error and halts the build:
```

This no longer injects scalaVersion at the project level, which was interfering with crossScalaVersions delegation to ThisBuild scope.
Fixessbt/sbt#3353
This is modification of crash log event logging that was added in sbt/util#85.
Instead of using the hardcoded 0 as the default value, this introduces `setTrace(..)` to `ConsoleAppender` like `BasicLogger`. Also the default value is set to `Int.MaxValue` that will display the full stack trace.
Fixessbt/sbt#3343
Fixes sbt/sbt#3348
Ref #101
The new logger, based on log4j separates the concern of the log producer (Logger) and the handlers that takes actions (Appender, e.g for displaying on Console). As such filtering of color should be performed only in the ConsoleAppender.
