Can I suppress IntelliJ "Unused declaration" inspection for fields?

Question

I would like to suppress the "Unused declaration" inpection in IntelliJ (2021.1, also tested on 2020.2) for all fields matching a certain pattern. I was able to suppress the warning for methods using the "Code patterns", but fields don't seem to be affected.

Due to project size, I really need to do that with a pattern to avoid adding annotations to every relevant field.

Here is my test class:

public class TestInspection {

    public static final String SUPPRESSED_NAME = "test";
    public static final String CONSTANT_NAME = "importantConstant";
    
    public void testSuppressedMethod() {
    }
    
    public void testMethod() {
    }
}

These are my settings:

And here are the warnings: I would like to remove the first warning (Field 'SUPPRESSED_NAME')

Does anyone have any ideas?

Answer 1

Yes, you can annotate the field with @SupressWarnings("unused")

@SuppressWarnings("unused")
public static final String SUPPRESSED_NAME = "test";

As stated in What is the list of valid @SuppressWarnings warning names in Java? you need to check what types of suppressions are available to you based on your environment.

It does not seem to be possible right now. If you want, you can vote for this feature request:
