Good question.
Running mvn clean install my build does not inform of anything:

How does it work? This class doesn't have a main?
My mvn package run fails on:
[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:java
(default) on project logging-log4j2: An exception occured while executing the
Java class. The specified mainClass doesn't contain a main method with
appropriate signature.

You are ritght, It Works with
<configuration>
<mainClass>org.apache.logging.log4j.core.config.plugins.processor.PluginProcessor</mainClass>
<arguments>
<argument>${project.build.outputDirectory}</argument>
<argument>com.globalavl.commons.log4j</argument>
</arguments>
</configuration>
And generates the dat file in META-INF

I now see that the documentation is not up to date. 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System.err.println("WARNING: this tool is superseded by the annotation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...
Catch 22?
Best Regards,
Yair Ogen

I missed that.
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WARNING: this tool is superseded by the annotation processor included in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.
And in the file system I have an empty directory:
\target\generated-sources\annotations

Do you build with maven? 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.
