Error SL4J - when Trying to test a viewpoint

Whenever I do a “Run” or “Run Configuration” for my “viewpoint DSL Project”, i run into this erros:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See for further details.

Then An instance of Capella is opened nevertheless. I was wondering what is the reason for this error. Thank you.
