Suppress duplicate warnings in IntelliJ IDEA by annotation

Question

Since version 15, IntelliJ warns me about code duplicates.

In some cases this might be intentional, so I want to ignore/suppress this warning by using the @SuppressWarnings annotation. But what is the correct value for this?

Edit: I'm not asking for disabling this kind of inspection completely as in question Is it possible to disable duplicate code detection in Intellij?

Answer 1

This works for me. You have to set it on both classes/methods if you want to suppress the warning both places.

@SuppressWarnings("Duplicates")
private void myDuplicatedMethod() {
    ...
}

Answer 2

Just saw this and thought I would throw this in for posterity. To suppress for just one block rather than the whole method, you can use a line comment:

//noinspection Duplicates

(I also find it handy to do this for unchecked) (I'm using version 2016-2, but I think this has been around awhile)

Answer 3

Thank you for all the answers. There is also another more generic approach to suppress warnings:

1. Place the cursor within the code that gives you a warning
2. Hit Alt+Enter
3. Go to the warning entry (in this case "Navigate to duplicate")
4. Don't hit Enter but → (right arrow)
5. Now you can select some suppressing options (for class/method/statement)
