Answer 1

i know this is an old question but thought to answer this as it might be helpfull to someone else.

I faced the similar issue and i resolved it by doing 2 changes 1.) moved the slf4j jar above the logback-core and logback-classic jars 2.) downloaded new slf4j jar version slf4j.api-1.6.1.jar
