Hi Mihai,
Looking at the output it seems that while logback-classic.jar is
visible to slf4j-api, logback-classic.jar is somehow no longer visible
when Gaffer (logback's groovy configurator) tries to parse the
logback.groovy file, which is quite unexpected.
Have you tried asking for help on the gradle lists?
Have you tried reproducing the problem in a tiny/minimal gradle project
without any dependencies on org.vertx or org.jboss.netty?
On my end I am looking at the class loader used when the GroovyShell
(which Gaffer uses) parses groovy scripts which might explain the issue.
