Document that spring-boot-configuration-processor cannot detect default value defined externally

[wangliang181230]

<artifactId>spring-boot-configuration-processor</artifactId> cannot generate the default value to the spring-configuration-metadata.json when the field default value is a constant and the constant not in current class.

Depending on exactly where the constant is defined, I have a feeling that it may not be possible to access it from the annotation processor. Can you please expand a bit on what you mean by "and the constant not in current class". Is the constant defined in another class in the project that's being compiled, or is it an external dependency?

another class or another jar

Thanks. That's a bit ambiguous. Do you mean another class in another jar, or you have two different cases one where the class is in the same project and one where it is in another jar?

One case is another class in same project.
One case is another class in another jar.
