Gradle build fails due to lombok

I'm using Gradle 4.10.2 (but would be fine using the latest version to get it to work). Here's my gradle file:

plugins {
    id 'org.springframework.boot' version '2.2.5.RELEASE'
    id 'io.spring.dependency-management' version '1.0.9.RELEASE'
    id 'java'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
    jcenter()
}

ext {
    set('springCloudVersion', "Hoxton.SR3")
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.cloud:spring-cloud-starter-netflix-eureka-client'
    implementation 'org.springframework.cloud:spring-cloud-starter-openfeign'
    implementation 'com.fasterxml.jackson.dataformat:jackson-dataformat-xml'
    compileOnly 'org.projectlombok:lombok'
    annotationProcessor 'org.projectlombok:lombok'
    runtime 'org.springframework.boot:spring-boot-devtools'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

dependencyManagement {
    imports {
        mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
    }
}

When I execute bootJar, it fails with a lot of errors. The errors are all due to not finding getters, setters, etc. that are auto generated by lombok. How can I resolve the errors? I've seen other posts about this issue and they all recommend adding the lombok dependency as a annotationProcessor & compileOnly but I've already done this and still have this issue.

Update

Here are a couple of errors that I get:

C:\Users\user\eclipse-workspace\example\src\main\java\com\example\proj\service\CarService.java:60: error: cannot find symbol
            log.debug("calling for cars {} ", cars);
            ^
  symbol:   variable log
  location: class CarService
C:\Users\user\eclipse-workspace\example\src\main\java\com\example\proj\service\CarService.java:66: error: cannot find symbol
                CarDtoBuilder dtoBuilder = dtoBuilderByCar.getOrDefault(
                ^
  symbol:   class CarDtoBuilder
  location: class CarService

log should come from annotation @Slf4j. And the CarDtoBuilder is from @Builder(builderMethodName = "hiddenBuild") annotated on CarDto. Both are lombok annotations.

Update 2

Now trying Gradle 4.10.3. Same result. Here's output from gradle -v:

Update 3

I've tried this using Gradle 6 same result. I've tried using Windows and Mac... same result. I've tried using JDK 11 instead of JDK 8... same result.

Update 4

I'm using @Builder lombok annotation. I wonder if that is causing an issue.

Remove any references to static imports involving code generated by lombok. In my case, I had:

import static com.example.car.dto.CarDto.CarDtoBuilder;

CarDtoBuilder was generated via lombok @Builder on the CarDto class. Once resolved, the other lobmok compile related issues such as log symbol not found (created by @Slf4j) go away.

I don't see your lombok-plugin configuration on your build.gradle file.

I had to setup lombok on my project for gradle 4.10.3 and this is what I did:

group 'io.metadata'
version '1.11-SNAPSHOT'

apply plugin: 'java'

project.ext.set("spring.boot.version", "2.2.6.RELEASE")
project.ext.set("spring.core.version", "5.2.5.RELEASE")

buildscript {
    repositories {
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
    dependencies {
        classpath("io.freefair.gradle:lombok-plugin:5.0.0-rc4")
    }
}

subprojects {
    repositories {
        mavenLocal()
        mavenCentral()
    }

    apply plugin: 'java'
    apply plugin: 'io.freefair.lombok'
}

Check the apply plugin: 'io.freefair.lombok' and the dependencies defined for it on buildscript.

Note that I am using multi module project but either way you can use lombok plugin and apply it.

It is not mandatory to use lombok-plugin but it works very well and it's easy to do. You can follow the documentation here: https://plugins.gradle.org/plugin/io.freefair.lombok
