Hamcrest 및 JUnit의 빌드 순서로 인해 문제가 발생했기 때문에 라이브러리를 재정렬하면 문제를 해결할 수 있다.

hamcrest tests always fail
I am using hamcrest 1.3 to test my code. It is simply a die. I am trying to test it to make sure the number generated is less than 13. I had a print statement that printed what the number generated...

아래의 방법을 참고했다.
1. Add Latest Hamcrest Dependency into POM, from
here - https://mvnrepository.com/artifact/org.hamcrest/hamcrest-all
2 .Add Latest JUnit Dependency into POM,from
Here - https://mvnrepository.com/artifact/junit/junit
3. Remove Any JUnit libraries from the Build path.
4.After you have Completed all above steps , Refresh your Project and Run.
💪 해결
1. Hamcrest와 JUnit5의 의존성을 주입해준다. 아래 내용을 넣어주자.
....
<dependencies>
<dependency>
<groupId>org.hamcrest</groupId>
<artifactId>hamcrest-all</artifactId>
<version>1.3</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter</artifactId>
<version>5.5.0</version>
<scope>test</scope>
</dependency>
</dependencies>
...
<plugins>
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.22.1</version>
</plugin>
</plugins>
2. 해당 프로젝트를 우클릭 Properties 에 들어간다. 그리고 아래와 같이 JUnit Library를 삭제해준다.
