Affects PMD Version:
7.3.0
Rule:
UnusedPrivateMethod
Description:
UnusedPrivateMethod should not be reported for methods annotated with jakarta.annotation.PostConstruct or jakarta.annotation.PreDestroy since they are usually called by a container (for example Spring).
As a workaround, the annotations can be added to configuration:
<rule ref="category/java/bestpractices.xml/UnusedPrivateMethod">
<properties>
<property name="ignoredAnnotations" value="java.lang.Deprecated,jakarta.annotation.PostConstruct,jakarta.annotation.PreDestroy" />
</properties>
</rule>
However, I think such methods should be excluded by default.
Code Sample demonstrating the issue:
import jakarta.annotation.PostConstruct;
import jakarta.annotation.PreDestroy;
import org.springframework.stereotype.Component;
@Component
public class JakartaTest {
@PostConstruct
private void setup() {
}
@PreDestroy
private void cleanup() {
}
}
Expected outcome:
PMD reports a violation at lines 0 and 13, but that's wrong. That's a false positive.
