[3.5.0] java.lang.NoClassDefFoundError: com/typesafe/scalalogging/Logger

[ducminhgd]

My system information:

• Scala: 2.11.8
• SBT: 0.13.8

Import line in code file: import com.typesafe.scalalogging.Logger

Added these 2 lines in build.sbt file:

libraryDependencies += "ch.qos.logback" % "logback-classic" % "1.1.7"
libraryDependencies += "com.typesafe.scala-logging" %% "scala-logging" % "3.5.0"

Build successfully but when running jar file, I got this

All seems legit. Without more information, it's difficult to say... how are you running the jar file? Where are you running it?

[analytically]

Basically, if your dependency tree includes the older scala-logging-slf4j artifact you'll see this exception.
