If you use the standard logger: com.typesafe.scalalogging.Logger , the logger prints the stack trace for you.

You can just use it this way:

import com.typesafe.scalalogging.Logger
import org.slf4j.LoggerFactory

try {     
    throw new Exception("test message")
} catch {
    case e:Exception => logger.error("Exception " , e)
}

There is already an overload which is accepting 2 parameters, String and Throwable.
