Unable to load class [org.h2.Driver]... - 인프런

이미 h2 db 가 1.4.200 버전으로 설치되어있어서 maven 설정파일에도

<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <version>1.4.200</version>
</dependency>

이렇게 적고 실행했는데

이 오류가 떠서

jdbc:h2:~/test 로 먼저 연결해보고

jdbc:h2:tcp://localhost/~/test 다시 연결했는데도

해결이 안되었습니다.

그래서 h2db를 1.4.199로 재설치하고 (재설치할때 콘솔에서 데이터베이스 당연히 종료 했었습니다.)

jdbc:h2:~/test 로 먼저 연결,

jdbc:h2:tcp://localhost/~/test 다시 연결

과정을 동일하게 수행한 후

maven 설정파일도

<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <version>1.4.199</version>
</dependency>

로 다시 바꿔준 뒤에 새로고침해서 h2 1.4.199 라이브러리 설치된걸 확인한 후 어플리케이션을 실행해도 동일한 에러가 떴습니다.

기타 다른 질문사항에 올라온 java버전관련 해결방법이라던지 해봤는데 해결이 안됐습니다 ㅠ

참고하시라고 제 설정파일들과 소스파일 올려놓겠습니다.
