For a clearer explanation - If you look at the parent pom you will notice that there are two executions within the compiler plugin. The first is the default compile that excludes module-info.java, I have no idea why they decided to have this file have a .java extension since the file name seems to be illegal in prior releases and the syntax is unlike any other Java constructs. Second the Java 9 compiler is called to compile the module-info.java. The Java 9 compile runs in the process classes phase, which is important because the Java 9 compile MUST run after the maven bundle plugin as OSGi will barf on module-info.class.
Next, if you look at the pom for the API module you will see that the default compile excludes a few more classes as these will only compile with Java 9. The Java 9 compile then only compiles these classes. Finally, log4j-core actually invokes the compiler 3 times. The first will compile everything except for module-info.java, the second will run the annotation processor, and the third will compile module-info.java.
