Building With Lombok's @Slf4j And Eclipse: Cannot Find Symbol Log
Answer : You also have to install Lombok into Eclipse. See also this answer on how to do that or check if Lombok is installed correctly. Full Disclosure: I am one of the Project Lombok developers. I got the same error even after Lombok was installed. For me the solution was to add another lombok annotation (i used @Data) to my class after which the eclipse errors went away. Perhaps this force refreshed some cache. Of course, I simply deleted the @Data annotation afterwards. I also faced the similar issue on log and @Slf4j on my STS environment. To resolve this, here is what I did on spring tool suite (sts-4.4.0.RELEASE) and lombok-1.18.10.jar (current latest version available in mavenrepository). If having maven project, ensure lombok dependency added to it. Else you need manually add the jar to your project classpath. <!-- https://mvnrepository.com/artifact/org.projectlombok/lombok --> <dependency> <groupId>org.projectlombok</groupId> <artifa...
