Simple annotation processor library project with Maven

I am trying to create a simple library that defines annotations and annotation processors with Maven using Netbeans 12.3. This library will be used by a web project that uses the annotations.

The problem is that the processor classes are not found when compiling the library, although they are in the source: "Annotation processor 'bandung.processor.CommandProcessor' not found"

(The annotations worked fine in a non-Maven project under a previous version of Netbeans.)

Here is the POM:
