Serializable class without 'serialVersionUID'

Reports classes that implement Serializable and do not declare a serialVersionUID field.

Without a serialVersionUID field, any change to the class will make previously serialized versions unreadable.

Example:

class Main implements Serializable {
}

After the quick-fix is applied:

class Main implements Serializable {
  private static final long serialVersionUID = -1446398935944895849L;
}

When using a language level of JDK 14 or higher, the quickfix will also add the java.io.Serial annotation.

Use the following options to configure the inspection:

List classes whose inheritors should not be reported by this inspection. This is meant for classes that inherit Serializable from a superclass but are not intended for serialization.
Whether to ignore Serializable anonymous classes.

Inspection options

Option	Type	Default
Ignore subclasses of	StringList	[java.awt.Component]
Ignore anonymous inner classes	Checkbox	false
