How to configure a NATS appender in LOGBack
LOGBack assumes that you have a logback.xml configuration in your classpath.
See below a minimal logback.xml configuration that would send all the logging events to the output console and to a NATS topic called 'jenkins' to a local broker running on the localhost at port 4222.
config.xml
<configuration>
<appender name="NATS" class="com.gerritforge.logback.nats.NatsTopicAppender">

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
