안녕하세요 호돌맨님? 끝 물이라 말씀하시니 팬으로서 마음이 많이 아픕니다.

혹시 환경변수 설정법을 알 수 있을까요? 나머지 방법은 다 시도해보았습니다.

전부 해결했습니다! 감사합니다!!

안녕하세요.
호돌맨입니다.

저도 잘 모르겠습니다. 저도 이제는 끝 물인것 같습니다.

해당 오류는 intellij + gradle 조합으로 사용할때 저도 자주 접했었던 오류입니다.
자바 소스 문제는 아닐것 같습니다. gradle 설정관련 문제일 가능성이 높은데요 우선 참고 해보실만한 링크를 드리겠습니다.

1. 관련 링크

• https://blue-mina.tistory.com/94
• https://www.inflearn.com/questions/187788

2. 그래도 잘 안되시면 아래 설정대로 되어있는지 확인 해보시 바랍니다.

3. 프로젝트 재생성

git 등으로 소스 백업이 되어있으시면 intellij 프로젝트를 삭제 후 다시 import 해보시기 바랍니다.

4. 그래도 잘 안되시면 소스를 깃헙에 올리시고 주소를 알려주시면 제가 돌려보겠습니다.

감사합니다.

안녕하세요 호돌맨님?

Gradle 환경변수를 설정해주고 cmd에서 gradle build, stop을 몇 차례 실행 해 본 결과 이제야 다행히 gradle을 찾지 못하여 test 실행이 되지 않는 문제는 해결 했습니다. 감사합니다.

제가 그 후 문제가 생긴 부분은 따로 있는데요, 구글링을 해봐도 잘 이해가 가지 않았습니다. PostControllerTest.java 내의 test7번입니다. 호돌맨님 코드를 복붙 해 놓은 상황이구요. objectMapper.writeValueAsString(postEdit)에서 문제가 있는 것 같아 보이는데 한 번 봐주실 수 있으실까요? 귀한 시간 내주셔서 감사합니다.

스크린샷과 오류 전문입니다.
