Lombok is not being recognized in LibGDX project

I'm working on libGDX project and I want to use Lombok. I followed this short tutorial about using lombok in libGDX projects but unfortunately it does not working.

Situation looks like this - IntelliJ is recognizing lombok and does not complaining about get/set methods, but when I want to run project (using gradle) there's java compiler error like

error: cannot find symbol static builder

error: cannot find symbol method setBoardSize(float a, float b)

so basically Lombok is not being recognized.

Usually the advice is to set 'enable annotation processing' in the IntelliJ but I tried without a success - I also tried reinstalling the Lombok plugin, changing Lombok version to 1.18.8, adding to the build.gradle android section

annotationProcessor "org.projectlombok:lombok:1.16.6"

but nothing fixed the issue. I also believe that it is not issue of IntelliJ because when I'm trying to run project from gradle command line using

gradlew desktop:run

it is not working and I have the same stacktrace

Did anyone have the same issue? How to resolve this?

I'm attaching my build.gradle underneath

        mavenLocal()
        mavenCentral()

Ugh - so finally I found the issue and it was quite surprising. It turned out that my configuration was fine, IntelliJ was fine but Lombok itself has an issue I was not aware about - this issue is static import of builder() method, which completely messes up the bytecode of compiled classes and causes issues like mine

Basically all I had to do was to remove such imports as

import static com.antkowicz.project.MyClass.builder;

public MyClass getMyClass() {
    return builder().build();
}

and instead of this use 

import static com.antkowicz.project.MyClass;

public MyClass getMyClass() {
    return MyClass.builder().build();
}

Seems that this issue is well known but not going to be resolved soon (or ever) and it's nothing trivial - so basically the only thing we can do is to ommit static imports with Lombok (at least builder()) :)
