Once the processor is realized, we must now declare it so that it can be found by
the compiler. The simplest way to do this is to use the Java mechanism for services
declarations using the following steps:
1. Package your annotation in a JAR file.
2. Include a META-INF/services directory in this JAR file.
3. Include a file named javax.annotation.processing.Processor in
the META-INF/services directory.
4. Specify in this file the fully qualified names of the processors contained in the
JAR file (one processor per line).
The following screenshot shows the structure of the project that contains the Un-
finished annotation. Failing to put the annotation and the processor in the same
project as is the case of our example, you can use one project for annotations and
