------------------------------

Hi guys,
I have been just tripping over this and the error in LOG4J2-460. I tried to use log4j2 in a project last year, was hoping would be more stable by now, but been at it hours, and cannot get log4j2 to work.

I am using 2.0-rc1.

 Maven builds (while executing plugins) are failing with these mentioned errors. I really think this is still a significant issue. When trying to executing mvn command line to build a jar, these errors occur.

As you can see, it fails during the maven-compiler-plugin. I have tried adding the dependencies to the plugin, but no change.
