java - Junit Test error : org/junit/jupiter/api/extension/ScriptEvaluationException

I'm trying to run test code in springboot and it shows the error like below. I cannot understand what NoClassDefFoundError means in this case. I made a PostsRepository class for JPA usage and also wrote @Repository annotation there.

`org/junit/jupiter/api/extension/ScriptEvaluationException

`

this is the test code I wrote and I cannot figure out what went wrong. I already set everything in build.gradle and other test codes just ran all good yesterday.

 package com.junu.springboot.domain.posts;

import org.junit.After;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.util.List;

import static org.assertj.core.api.Assertions.assertThat;

@RunWith(SpringRunner.class)
@SpringBootTest
public class PostsRepositoryTest {
    @Autowired 
    PostsRepository postsRepository;

    @After 
    public void cleanup(){
        postsRepository.deleteAll();
    }

    @Test
    public void selectList(){
        postsRepository.save(Posts.builder()
                                .title(title)
                                .content(content)
                                .author("[email protected]")
                                .build());
        //when
        List<Posts> postsList = postsRepository.findAll();

        //then
        Posts posts = postsList.get(0);
        assertThat(posts.getTitle()).isEqualTo(title);
        assertThat(posts.getContent()).isEqualTo(content);
    }
}

I just guess that the annotaion @Autowired might be the reason because in my Intellij it shows a red line.

Anyone please help me :)
