Annotation processor issues after upgrading to Java 17 + Spring Boot 3

[Michael Baroody]

Hello. For the life of me, I can't figure out how to generate the Q classes after making the upgrade to Java 17 and Spring Boot 3. Here is my build.gradle: 

plugins {
id 'java'
id 'idea'
id "com.google.cloud.tools.jib" version "3.3.1"
id "io.spring.dependency-management" version "1.1.0"
id "org.springframework.boot" version "3.1.1"
id "com.diffplug.gradle.spotless" version "4.3.0"
}

ext {
set('mapstructVersion', '1.5.5.Final')
set('awssdkVersion', '2.17.82')
set('springCloudVersion', "2022.0.3")
set('queryDslVersion', '5.0.0')
set('lombokVersion', '1.18.28')
}

repositories {
mavenCentral()
}

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

java {
toolchain {
languageVersion = JavaLanguageVersion.of(17)
}
}

idea {
module {
sourceDirs += file("${project.buildDir}/generated/")
generatedSourceDirs += file("${project.buildDir}/generated/")
}
}

spotless {
java {
googleJavaFormat()
}
}

dependencies {

annotationProcessor "org.projectlombok:lombok:${lombokVersion}"

compileJava {
options.compilerArgs << '-Amapstruct.unmappedTargetPolicy=IGNORE'
}

group = 'com.mycompany.services'
version = tagName
description = 'my-service'

test {
useJUnitPlatform()
}

jib {
from {
image = "gcr.io/distroless/java:17"
}
to {
image = "company-repo"
def gitCommit = "${project.gitCommit}".toString()
tags = [gitCommit, "latest"]
}
container {
creationTime = "USE_CURRENT_TIMESTAMP"
}
extraDirectories {
paths {
path {
from = 'src/test/resources'
into = '/defaultconfig'
}
}
}
}

tasks.withType(JavaCompile) {
doFirst {
println "AnnotationProcessorPath for $name is \n\n${options.getAnnotationProcessorPath().getFiles().join("\n")}"
}
}

This results in this compilation error: 

 error: cannot find symbol                                                                                                                    
  private static final QDevice devices = QDevice.device;              
                       ^                                                                                                                      
  symbol:   class QDevice                                              
  location: class ServiceService                                                                                                       

I can confirm that the Q classes are not generated. 

Can anyone see anything obviously wrong with this configuration? Do you know how I can debug?
