Hi guys,
Got a little problem with the logging. My project is compiled with the help from maven. In my case i don't understand what ist going wrong! Maven is reporting that it can't load the specified class. I tried several variants in the pom.xml, but nothing help to get rid of the error. In this case I'm not shure how important the logging is for the whole project.

The error I got is:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation

Can anybody help?

Greetings 
Thorsten
