Expected behavior

Hi guys, how are you?

Thanks by awesome working that you are doing,

i'm here to report a bug that i've got :

when i'm trying to use the class Mappers.getMappers(SomeMapperClass.class)

with the component model = "spring"

and the injectionStrategy = InjectionStrategy.CONSTRUCTOR is configured,
with uses = {
OtherMapper.class
}

CODE:

@Mapper(componentModel = "spring", uses = {
        TechnologiesMapper.class
},injectionStrategy = InjectionStrategy.CONSTRUCTOR)
public interface ProjectsMapper {

    Project mapToProject(ProjectsDomain projectsDomain);

}

there's a bug that says "no such method error", i think i'ts because the others or whether you create more than one construtor at the class generated, it can solve because of the use of the reflection ...

Reading the PRs i see that AlexELin created a fix ...

Actual behavior

Error no suchMethodException

Steps to reproduce the problem

In the unit tests

package com.site.rfs.blog.dataproviders.mappers;

import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.mapstruct.factory.Mappers;
import org.springframework.test.context.junit.jupiter.SpringExtension;

import static org.junit.jupiter.api.Assertions.*;
@ExtendWith(SpringExtension.class)
class ProjectsMapperTest {

    private ProjectsMapper projectsMapper;

    @BeforeEach
    public void setUp(){
        this.projectsMapper = Mappers.getMapper(ProjectsMapper.class);
    }

    @Test
    public void test(){
        assertNotNull(this.projectsMapper);
    }

}

It throws a error:

java.lang.RuntimeException: java.lang.NoSuchMethodException:

Debugging the code it' happen when calling the line 49 of the method doGetMapper:

Constructor constructor = implementation.getDeclaredConstructor() at the

When i change the injection strategy, it's change the behavior and i'ts work:

InjectionStrategy.SETTER
or
InjectionStrategy.FIELD(default);

Please accept the fix of AlexELin, it'll help everyone
