Complete “Scala Logging” Example

Question

I\'m trying to use Typesafe\'s Scala Logging but couldn\'t get it to print any debug message. I expect Scala Logging to print debug message to the default screen but it does

You're close, but you have to declare a logger instance using an SLF4J logger in the apply method for the Logger companion in com.typesafe.scalalogging. In your build.sbt include:

libraryDependencies += "com.typesafe.scala-logging" %% "scala-logging" % "3.1.0"

libraryDependencies += "org.slf4j" % "slf4j-api" % "1.7.10"

Then this will work:

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

class MyClass extends LazyLogging {
  // ...
  val logger = Logger(LoggerFactory.getLogger(this.getClass))
  logger.debug("Here goes my debug message.")
  // ...
}

Here is a reference for LoggerFactory. Hope it helps!
