如何在Gradle build中为测试范围映射器接口生成Mapstruct映射器实现？

dependencies {
    implementation 'org.mapstruct:mapstruct:1.4.2.Final'
    annotationProcessor 'org.mapstruct:mapstruct-processor:1.4.2.Final'
}

import org.mapstruct.Mapper;
import org.mapstruct.Mapping;

@Mapper
public interface UserMapper {
    @Mapping(source = "name", target = "fullName")
    UserDto userToUserDto(User user);
}

plugins {
    id 'java'
    id 'org.mapstruct' version '1.4.2.Final'
}

dependencies {
    implementation 'org.mapstruct:mapstruct:1.4.2.Final'
    annotationProcessor 'org.mapstruct:mapstruct-processor:1.4.2.Final'
}

// 配置Mapstruct插件
mapstruct {
    componentModel = 'jsr330'
}

// 配置生成Mapstruct映射器的实现类
compileJava {
    options.annotationProcessorGeneratedSourcesDirectory = file("src/generated/java")
}

import org.junit.Test;

public class UserMapperTest {
    private UserMapper userMapper = new UserMapperImpl();

    @Test
    public void testUserToUserDto() {
        User user = new User();
        user.setName("John Doe");

        UserDto userDto = userMapper.userToUserDto(user);

        // 验证映射结果
        assertEquals("John Doe", userDto.getFullName());
    }
}
