SerializableInnerClassHasSerialVersionUIDField

Reports non-static inner classes that implement java.io.Serializable, but do not define a serialVersionUID field.

Without a serialVersionUID field, any change to the class will make previously serialized versions unreadable. It is strongly recommended that Serializable non-static inner classes have a serialVersionUID field, otherwise the default serialization algorithm may result in serialized versions being incompatible between compilers due to differences in synthetic accessor methods.

A quick-fix is suggested to add the missing serialVersionUID field.

Example:

class Outer {
      class Inner implements Serializable {}
  }

After the quick-fix is applied:

class Outer {
      class Inner implements Serializable {
          private static final long serialVersionUID = -7004458730436243902L;
      }
  }

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.
