How do generate this value in IntelliJ IDEA?

I go to Settings -> Errors -> Serialization issues -> Serializable class without ‘serialVersionUID’, but it still doesn't show me the warning. My class PKladrBuilding parent implements interface Serializable.

Part of the code:

public class PKladrBuilding extends PRQObject

public abstract class PRQObject extends PObject

public abstract class PObject implements Serializable

I am not sure if you have an old version of IntelliJ IDEA, but if I go to menu File → Settings... → Inspections → Serialization issues → Serializable class without 'serialVersionUID'` enabled, the class you provide give me warnings.

If I try the first class I see:

BTW: It didn't show me a warning until I added { } to the end of each class to fix the compile error.
