When I used Eclipse it had a nice feature to generate serial version UID.
But what to do in IntelliJ?
How to choose or gen
Easiest 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.
