Lombok @Log4j2 annotation doesn't work in IntelliJ IDEA

Question

I'm using Lombok library in my project and have a problem with @Log4j2 annotation. Not sure why but it's not generating log field in the class.

But when I'm changing annotation to @Slf4j it works, I can see it in IntelliJ IDEA 'Structure' tab.

I'm using gradle as a build tool. Have few dependencies"

dependencies {
    compileOnly("org.projectlombok:lombok")
    compile("org.springframework.boot:spring-boot-starter-log4j2")
}

@Serghey I can see next dependencies https://snag.gy/7fDA6y.jpg — Orest, Mar 16 '17 at 10:15
Actually log4j2 works through Slf4j, because it uses log4j2.xml configs. Just wondering why annotation is not working — Orest, Mar 16 '17 at 10:16
It could be that the IDEA plug-in doesn't support @Log4j2 yet. If that's the case IDEA will show an error message, but compiling the code should work. — Roel Spilker, Mar 17 '17 at 10:19
This option works for me: dependencies { compileOnly 'org.projectlombok:lombok:1.18.8' annotationProcessor 'org.projectlombok:lombok:1.18.8' } — Yevhenii Tsybaiev, Jul 14 '19 at 16:46

So I had the same problem, I think. What I did is I installed the Lombok plugin in IntelliJ, enabled the annotation as in the link under Preferences-> Build, Execution, Deployment > Compiler > Annotation Processors. And then I restarted IntelliJ, and it worked. IDE is able to recognize log.

I tried it for log4j, log4j2 and slf4j. It all worked.

Let me know if this helped.

I am on IntelliJ Idea 2020.2 Mac Version with lombok plugin 0.32-2020.2. In addition to the above answer I also had to turn on log annotation in lombok plugin settings (Preferences > Other Settings > Lombok Plugin > Enable @Log support) – rahulmohan Oct 23 '20 at 02:40
