[logback-user] org.slf4j.impl.StaticLoggerBinder.SINGLETON

[stlecho]

I'm using the underneath listed dependencies and I'm receiving the same error
message: "java.lang.reflect.InvocationTargetException:
java.lang.IllegalAccessError: tried to access field
org.slf4j.impl.StaticLoggerBinder.SINGLETON from class
org.slf4j.LoggerFactory". 

What could I do to correct this ?
