vscode，java使用mapstruct不生成Impl类

Question

问题遇到的现象和发生背景

vscode编辑器下，java语言、技术：mapstruct；
1、通过gradle的tasks，可以正常编辑程序，且可以生成Impl类；
2、但直接F5调试，vscode编辑器下，不能生成Impl类，导致出错；在Idea编辑器下可以直接运行（不通过gradle）；
interface CarMapper接口，不能自动生成OrderMapperImpl实现类。

我网上浏览了很多网页，没找到解决办法，相同问题如：

运行结果及报错内容

Action:
Consider defining a bean of type 'com.example.demo.Service.CarMapper' in your configuration.

我的代码片段

import org.mapstruct.Mapper;
import org.mapstruct.Mapping;
import org.mapstruct.ReportingPolicy;
import org.mapstruct.factory.Mappers;

@Mapper(componentModel = "spring", unmappedTargetPolicy = ReportingPolicy.IGNORE)
public interface CarMapper {
    CarMapper INSTANCE = Mappers.getMapper( CarMapper.class ); 
 
    @Mapping(source = "numberOfSeats", target = "seatCount")
    CarDto carToCarDto(Car car); 
}

###build.gradle文件

```java
plugins {
    id 'org.springframework.boot' version '2.5.7'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.mybatis.spring.boot:mybatis-spring-boot-starter:2.2.0'
    implementation 'org.mapstruct:mapstruct:1.3.1.Final'
    compileOnly 'org.projectlombok:lombok'
    developmentOnly 'org.springframework.boot:spring-boot-devtools'
    annotationProcessor 'org.projectlombok:lombok'
    annotationProcessor 'org.mapstruct:mapstruct-processor:1.3.1.Final'
    annotationProcessor 'com.google.auto.value:auto-value:1.5'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

###### launch.json文件

```java
    "version": "0.2.0",
    "configurations": [       
        {
            "type": "java",
            "name": "Launch DemoApplication",
            "request": "launch",
            "mainClass": "com.example.demo.DemoApplication",
            "projectName": "demo"           
        }
    ]

####编译后结果
1、bin文件夹下vscode直接运行程序创建的目录；
2、build文件夹是gradle的tasks运行后产生的目录，可以看出来已经生成了OrderMapperImpl类；
