<p>저역시 명확한 답을 얻지 못하였습니다.&nbsp;</p>
<p>현재는 다운그래이드해서 사용중이지만 본질적인 문제해결이 아니라서 답답한 면이 있습니다.</p>
<p>정확한 이유를 알게되면 답변 달도록 하겠습니다.&nbsp;</p>
<p>수고하세요&nbsp;</p>

안녕하세요. noClassDefFoundError Q 파일을 찾지 못하는 문제 문의 드립니다.

<p>확인을 좀 더 해보니 현재 개발중인 코드에서는 문제가 없었는데,</p>
<p>이전 소스를 git에서 받아서 테스트 해보니&nbsp; Qclass 참조가 안되네요&nbsp;</p>
<p>그래서 좀 찾아봤는데 최근에 Java Test Runner,&nbsp; Debugger for java 가 업데이트 되었습니다.&nbsp;</p>
<p>다시 downgrade 시켜서 실행해 보니 잘 동작하더군요.</p>
<p>버전을 아래와 같이 수정하시고&nbsp;</p>
<p>0.22.4</p>

<p>Ctrl + Shift + p > clear the java language server workspace&nbsp;&nbsp;</p>
<p></p>
<p>수고하세요&nbsp;</p>

<p>안녕하세요 &nbsp;</p>
<p>vscode에서 현재 정상 동작됩니다 .&nbsp;</p>
<p>우선 vscode에서 spring을 사용하기위한&nbsp; Extenstions 버전을 확인해 보시면 좋을 것 같습니다.</p>
<p>아래와 같은 버전인지 확인해 주시고 Debugger for java는 아래 버전(0.25.1)으로 맞춰주세요&nbsp;</p>
<p><img src="https://cdn.inflearn.com/public/comments/22602166-27ab-434b-b3de-dff27105f84a/캡처1.PNG" title="캡처1.PNG" width="535" height="377" alt="" /></p>

<p>그리고 build.gradle 파일을&nbsp; //querydsl&nbsp; 주석 위주로 본인 코드와 비교해 보시면 될 것 같습니다.</p>

<p>어쩌다보니 자답입니다 ....&nbsp;</p>
<p>질문글을 지울까 하다가 다른분들에게 혹시 도움일 될까 싶어 글 남깁니다.&nbsp;</p>
<p>Visual studio code Spring framework tools 중</p>
<p>Debugger for java 버전이 3일 전에 업데이트 되면서 발생된 문제&nbsp;</p>
<p>0.26 -> 0.25.1&nbsp; 다운그레이드로 해결&nbsp;</p>

<p>현재 진행상황은 아래와 같이 연관관계 자식인 watch를 먼저 지우고 live를 지우는 방식으로</p>
<p><strong>cascade 를 활용하지 못하는 방식</strong>으로 처리 하고 있습니다.&nbsp;</p>

</div>
</div>
</div>
<p></p>
<p>궁극적으로는 cascade를 활용해서 깔끔하게 <strong>live만 delete 하면 watch가 지워지는 동작을 구현</strong>하고자 합니다.&nbsp;</p>
<p>감사합니다.&nbsp;</p>
<p></p>

양방향 연관관계 설정 후 bulk delete 실행시 문제점 문의드립니다.

<p>이미 해결하셨는지 모르겠지만 저는 아래와 같은 방법으로 해결 하였습니다. (IDE vscode)</p>
