How can I change the formatting of arrays within annotations in Eclipse?

I have the following code in a Java file within Eclipse:

@Annotation({"arg1", "arg2"})
public void method() {
    ...
}

I have an issue whereby CheckStyle dislikes that particular formatting and warns that:

Whitespace Around: '}' is not preceded with whitespace.

However the eclipse formatter will not allow me to add any whitespace and will remove it whenever I format.

If I just wanted to remove the warning then I would have to disable the Whitespace Around rule for } within CheckStyle, but then it won't warn me when I screw up in other places, so don't want to do that.

The authors of CheckStyle have added the option I would need, by allowing you to ignore Annotation Array Initialization curlies as it does for Array Initialization outside of annotations. However, CheckStyle have not released a new version with the update and have no roadmap for when they will do so.

In any case, lets say that I agree with CheckStyle and would like a space before the }, how can I configure the formatter with my preference, or at the least, to not care about this issue?

I am aware of @formatter:off, I am hoping for a one off solution in the formatter configuration, not something I have to use every time I use an array within an annotation.

Check your settings under Preferences -> Java -> Code Style -> Formatter. Then Edit your active profile and check under White Space -> Arrays -> Array initializers.

There you can tell Eclipse to use White Space characters before and after the brackets. enter image description here
