Lombok with IDEA 13: Cannot find symbol

Question

I have tried using Lombok on Intellij IDEA 13 Ultimate. However. I get the famous error "cannot find symbol" for all the methods that should have been available when I am using specific annotations for example the once I use as annotations are @Builder, @AllArgsConstructor and @Data.

I have already set my compiler to enable annotation processing and I have looked deeply into it, but with no solution of how to solve it.

Any advice or tips would be nice.

Have you installed the lombok plugin for IDEA? plugins.jetbrains.com/plugin/6317 – Zweig

jupp. the latest one – Pentomic

Are you using Maven? Have you made sure that the jar is on the classpath? – Zweig

Have you solved it already? It's happening to me too. – Merely

Answer 1

Kind of old question here, but I came across the same problem today. I had to do two things to make it work:

1. Set annotation processing on: Settings -> Compiler -> Annotation Processors
2. Change from ajc to javac for the project: Compiler -> Java Compiler

you of course also need the Lombok plugin.

If i do this, Lombok works, but aspectJ doesn't. Am I missing something? – Hardeman

@prashantkute are you able to fix your issue. i am also facing the same – Closing

Answer 2

In my case non of methods works. But I found solution for my case. I needed to add to my Gradle dependencies list of

dependencies {
    compileOnly 'org.projectlombok:lombok:1.18.22'
}

one more line

dependencies {
    compileOnly 'org.projectlombok:lombok:1.18.22'
    annotationProcessor 'org.projectlombok:lombok:1.18.22'
}

With such combination you even don't need enabling Annotation Processors from @Vegard answer.

Answer 3

In my case apart from enabling Annotation Processing and installing Lombok Plugin I had to rebuild project by Build -> Rebuild Project

Answer 4

I have the same problem. Using maven, after I add at to my pom.xml annotationProcessor nothing changed. Also I'm installed Lombok plugin at Intelij IDEA.

<annotationProcessorPaths>
    <path>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <version>1.18.20</version>
    </path>
</annotationProcessorPaths>

Answer 5

I was having a similar issue, but resolved it by upgrading to IDEA 15.0.2 and Lombok plugin 0.9.6.14. I had to restart IDEA several times before all of the getters/setters generated by Lombok were resolved.

I also found this related answer, but it didn't seem to help my problem. It may help you if upgrading does not.

Answer 6

Tried with the @Mike's solution above, and it works. For your information, even though I enabled the Annotation Processors , but it seems like not working. After I added the annotationProcessor 'org.projectlombok:lombok:1.18.22' it was built successfully.

If you use intellij Idea go to setting and add Lombok plugin to your intellij idea

Answer 8

I solved this in my Gradle project by including the Lombok plugin. No dependencies or annotationProcessor needed (nor did those work for me).

For example in your build.gradle.kts:

plugins {
    id("io.freefair.lombok") version "6.5.1"
}

Answer 9

The aforementioned solutions work perfectly, although there's another instance where Lombok annotation processing can fail:

In Gradle or Maven you can pass an argument/flag to prevent annotation processing:

-proc:none

Hope this helps someone.

Answer 10

If you use @UtilityClass, the reason can be: Due to a peculiar way javac processes static imports, trying to do a non-star static import of any of the members of a @UtilityClass won't work. Either use a star static import: import static TypeMarkedWithUtilityClass.*; or don't statically import any of the members.

Answer 11

Same problem here, hundreds of Lombok errors in @Builder tags and getting this compile error cannot find symbol.

The solution for me was to check all the errors and see that one of them was different import requires canonical name for caused by the @FieldNameConstants annotation conflicting with other classes.

Conclusion: Lombok sucks!
