Affects PMD Version: 6.12.0
Rule: UnusedPrivateField
Description:
Lombok @Delegate on a member, means that lombok will generate methods into the class which mirror the method signatures of that member variable, and the bodies of the methods are just a simple delegation to the member. Obviously it makes use of the member variable; so it should not trigger PMD's UnusedPrivateField rule, but it does.
https://projectlombok.org/features/Delegate.html
Code Sample demonstrating the issue:
public class Foo {
@Delegate private Bar bar;
}
Running PMD through: Maven -- but with dependency override to PMD version 6.12.0.
P.S. I think there could be a workaround, using violationSuppressXPath to suppress the UnusedPrivateField on members with the Delegate annotation. But I haven't yet figured out the XPath to match it. If an XPath wizard wants to share the right incantation it would be much appreciated!
