I tried to create a simple project via IntelliJ IDEA 2016.3:

Answer 1

According to the Spring Boot docs, the correct configuration since Gradle 4.6 is

dependencies {
    annotationProcessor group: 'org.springframework.boot', name: 'spring-boot-configuration-processor'
    // ...
}

IntelliJ IDEA supports annotationProcessor scope since build 193.3382 (2019.3). Don't forget to enable annotation processing in IntelliJ IDEA settings.
