忽略所有过时的类和方法的checkstyle警告

Question

Can I somehow ignore any warning for deprecated class?

For example:
I had following warnings AvoidEscapedUnicodeCharacters , NonEmptyAtclauseDescription for deprecated class.

How to ignore all of them?

Answer 1

Checkstyle allows you to write your own custom filters . You can use SuppressWarningsFilter as a basis, because this filter is filtering based on annotations as well. You'd just need to change the annotation that you're looking for.

public class SuppressWarningsFilter
    extends AutomaticBean
    implements Filter {

    @Override
    protected void finishLocalSetup() {
        // No code by default
    }

    @Override
    public boolean accept(AuditEvent event) {
        return !SuppressWarningsHolder.isSuppressed(event);
    }
}

Pretty simple, but all of the logic is in SuppressWarningsHolder . That code is a few hundred lines, but you should be able to copy and paste a lot of it, and probably remove a large chuck as well.

I've implemented this: https://github.com/michaelboyles/checkstyle-annotation-filter . I'll make it available via the central repository at some point.

Answer 2

You just need to add the line below:

@SuppressWarnings("deprecation")

It will ignore all deprecated methods in your code. I hope this will help.
