Плагин Maven Lombok на Java 10: аннотации не найдены в Maven
Я знаю проблему IDE не понимая ломбок. Но сейчас, в новом проекте, у меня есть противоположная проблема: идея понимает это, а maven - нет.
Когда я добавляю плагин lombok в maven и запускаю чистую установку, плагин lombok не может преобразовать классы, потому что утверждает, что пакет lombok не существует.
Это мой pom.xml:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

(примечания от pom: уровень языка - java 10, исходная кодировка utf-8, я использую мозаичные модули в многокомпонентной сборке)
ошибки, которые я получаю, примерно такие. Я попытался установить область действия org.projectlombok:lombik для компиляции или предоставления, без каких-либо различий в результате.
Я был бы очень благодарен, если бы у кого-нибудь была идея, как это исправить?

Обновление конфигурации до следующего может помочь решить проблему:

Я дал этому попытку и целевые файлы, созданные с помощью команды mvn clean install имеет код деломбокса следующим образом:
Хотя после генерации я вижу в IDE сообщение "module-info.java уже существует в модуле".
