Intellij refactoring, disable/customize generating "@org.jetbrains.annotations.NotNull"

Question

Every time I extract method, this line is generated "for me":

@org.jetbrains.annotations.NotNull

around the method. 1. I don't have this on my class path, so it does not compile 2. even if I have, I don't want to include jetbrains annotations in my project. Even if I have more suitable (maybe) javax.validation.constraints.NotNull annotation on class path, intellij does not use that one.

questions:

1. how to turn it off entirely?
2. how to customize, which annotation to use?

Answer 1

The extract method dialog has a Generate annotations check box. When disabled it does not generate the nullability annotations. The state of this check box is remembered between invocations, so disabling it once is enough.

If this check box does not appear, annotations for the extracted method should not be generated.

It is possible to customize the annotation used in the settings of the Java | Probable bugs | Constant conditions & exceptions inspection. The configuration dialog looks this: Use the check mark button, to mark the selected annotation as the one that should be used for code generation.

Answer 2

I ran into the same problem and was able to fix it by follow these steps :

Go to Settings > Editor > Inspections >

Find Java > Probable Bugs > Nullability Problems > @NotNull/@Nullable Problems

Click Configure Annotations button and check these items

Answer 3

With IntelliJ 2024

I could not find the option in the settings. However, I could find it on the method extraction popup

Notice the subtle hint "Press Alt+Maj+O to show options popup"

The keys combination shows this short popup:

In this popup it's possible to toggle annotation generation.

Ctrl+Alt+M shows the popup mentioned earlier:

I was unable to find this option pane in the settings. I'm a little disappointed as JetBrains used to be quite good in UX
