I'm installing Scalding and sbt on my system but running command sbt assembly gives the following error:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
I had a similar issue on AWS DynamoDB client. I resolved it by adding the following dependencies to maven pom.xml
If you're not compiling, but just running binaries, download the slf4j-api-1.7.30.jar and slf4j-simple-1.7.30.jar jars and put them on the classpath.
