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.

Start by reproducing the setup with the listed Gradle settings and the cleanEclipse and eclipse tasks, comparing Gradle 7.1.1 with the working Gradle 6.9 and net.ltgt.apt-eclipse plugin. Investigate the Eclipse and annotation-processing configuration; done means the required .factorypath is generated without that plugin and MapStruct works in Eclipse.
