             Summary: scala: add support for creating custom plugins
                 Key: LOG4J2-1741
                 URL: https://issues.apache.org/jira/browse/LOG4J2-1741
             Project: Log4j 2
          Issue Type: Improvement
          Components: Plugins
            Reporter: PJ Fanning


I tried to add a custom appender using Scala but the pattern of having a class 
with an Plugin annotation and a static method on that class with a 
PluginFactory or PluginBuilderFactory annotation doesn't seem to work in Scala.
In Scala, you can create a companion object to a class where you can implement 
the equivalent of static methods but these are not the same class under the 
hood. The Scala compiler builds 2 or more classes, the companion object gets a 
class name with a $ appended to it. I think this is affecting the lookup for 
the method with the Factory annotation.
