How does it work? This class doesn't have a main? My mvn package run fails on:

The main class should be: org.apache.logging.log4j.core.config.plugins.processor.PluginProcessor as indicated in PluginManager: /** * Process annotated plugins. * @deprecated Use {@link org.apache.logging.log4j.core.config.plugins.processor.PluginProcessor} instead. To do * so, simply include {@code log4j-core} in your dependencies and make sure annotation processing is not disabled. * By default, supported Java compilers will automatically use that plugin processor provided {@code log4j-core} * is on the classpath. */ @Deprecated // use PluginProcessor instead public static void main(final String[] args) { System.err.println("WARNING: this tool is superseded by the annotation processor included in log4j-core."); System.exit(-1); } However, PluginProcessor doesn't contain a main...

Added to my pom - should running mvn package be enough to generate the file? It looks like it doesn't. I see this warning: WARNING: this tool is superseded by the annotation processor included in log4j-core.

The Plugin Preloading section <http://logging.apache.org/log4j/2.x/manual/plugins.html#Plugin_Preloading> on the Plugins page gives a sample snippet to add to your pom.xml to make Maven generate the *.dat file for your plugins. > The same applies to my configuration plugin.
