Mapstruct Annotation Processor does not seem to work in Intellij with Gradle project

I'm trying to use Intellij 2017 Ultimate to build/run a Spring Boot application that uses MapStruct. It is a Gradle project. My issue is that IntelliJ does not seem to run the MapStruct Annotation Processor. I realize that I can configure IntelliJ to delegate to the Gradle build process (see this), but I am hoping to simply configure IntelliJ to use APT to generate the necessary classes itself.

I have enabled APT for my project, but my classes are still not generated.

build.gradle (applicable snippets):

ext {
    mapstructVersion = '1.2.0.Final'
}

plugins {
    id 'net.ltgt.apt' version '0.15'
}

dependencies {
    // MapStruct support
    implementation group: 'org.mapstruct', name: 'mapstruct-jdk8', version: mapstructVersion
    annotationProcessor group: 'org.mapstruct', name: 'mapstruct-processor', version: mapstructVersion
 }

IntelliJ configuration:

Yet, when I do a ./gradle clean followed by a Build->Rebuild Project, my out/production/classes/generated folder is empty.

Is there something additional that I need to do to enable APT on this project? Should IntelliJ automatically detect the mapstruct annotation processor in the classpath?

Finally it is working fine 👍 with Intellji 2018.1 CE. we don't need any apt plugins.

Here is updated gradle file

plugins {
    id 'java'
}

repositories {
       mavenCentral()
       mavenLocal()
}
sourceCompatibility = JavaVersion.VERSION_1_8


dependencies {
      compile group: 'org.mapstruct', name: 'mapstruct-jdk8', version: '1.2.0.Final'
      compileOnly 'org.mapstruct:mapstruct-processor:1.2.0.Final'
      annotationProcessor 'org.mapstruct:mapstruct-processor:1.2.0.Final'
      compileOnly ("org.projectlombok:lombok")
      testCompile 'junit:junit:4.12'
}

Please make sure following things are configured properly

1. Enable Annotations Processors( Preference->Build Execute Deployment ->Compiler->Annotations Processors )

2. MapStruct plugin

3. Lombok plugin
