Annotation processors are added to compileOnly and annotationProcessor but we configure compileOnly to extend annotationProcessor

[wilkinsona]

Example build.gradle script:

plugins {
  id 'java'
  id 'org.springframework.boot' version '3.0.3-SNAPSHOT'
  id 'io.spring.dependency-management' version '1.1.0'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'

configurations {
  compileOnly {
    extendsFrom annotationProcessor
  }
}

repositories {
  mavenCentral()
  maven { url 'https://repo.spring.io/milestone' }
  maven { url 'https://repo.spring.io/snapshot' }
}

dependencies {
  implementation 'org.springframework.boot:spring-boot-starter'
  compileOnly 'org.projectlombok:lombok'
  annotationProcessor 'org.projectlombok:lombok'
  testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

tasks.named('test') {
  useJUnitPlatform()
}

Configuring compileOnly to extend from annotationProcessor means that org.projectlombok:lombok doesn't need to be declared in both compileOnly and annotationProcessor.
