Mapstruct issue on Eclipse (1.4.2.Final)

I have an issue to setup Mapstruct on eclipse (Version: 2021-03 (4.19.0), Build id: 20210312-0638) with following gradle setting:

implementation "org.mapstruct:mapstruct:$mapstructVersion"
annotationProcessor "org.mapstruct:mapstruct-processor:$mapstructVersion"
annotationProcessor "org.projectlombok:lombok-mapstruct-binding:0.2.0"
annotationProcessor "org.projectlombok:lombok"
annotationProcessor "org.springframework.boot:spring-boot-configuration-processor"

It seems it doesn't generate .factorypath when I tried to run gradle tasks: cleanEclipse and eclipse
It works and everything is fine if I add follow gradle plugin:

plugins {
id 'java'
id 'eclipse-wtp'
id 'org.springframework.boot' version '2.3.12.RELEASE'
id 'io.franzbecker.gradle-lombok' version '4.0.0'
id 'net.ltgt.apt-eclipse' version '0.21'
}

But there is a drawback that this net.ltgt.apt-eclipse doesn't work on gradle 7.1.1 and I need to use the older version gradle-6.9
However developers like me prefer to install MapStruct Eclipse Plugin and it's supposed to make things work around without require developers to add net.ltgt.apt-eclipse

I look forward to this potential fix.

Regards.

まず、記載されている Gradle 設定と cleanEclipse および eclipse タスクを使ってセットアップを再現し、Gradle 7.1.1 を、動作する Gradle 6.9 および net.ltgt.apt-eclipse プラグインと比較します。Eclipse とアノテーション処理の設定を調査します。完了の条件は、そのプラグインなしで必要な .factorypath が生成され、Eclipse で MapStruct が動作することです。
