IntelliJ IDEA generating serialVersionUID

Question

How do generate this value in IntelliJ IDEA?

I go to Settings -> Errors -> Serialization issues -> Serializable class without ‘serialVersi

Answer 1

Easiest modern method: Alt+Enter on

private static final long serialVersionUID = ;

IntelliJ will underline the space after the =. put your cursor on it and hit alt+Enter (Option+Enter on Mac). You'll get a popover that says "Randomly Change serialVersionUID Initializer". Just hit enter, and it'll populate that space with a random long.
