에러는 대강 이렇다.

대강 JVM 메모리가 턱없이 부족하다는 것.

그래서 자바 관련된 오만 메모리를 건드리고 테스트 하다가 실신할 뻔 했다.

회사 코드가 워낙 방대하다 보니... 리비전도 30만개에 용량도 어마어마...

결론은 팀시티 웹페이지에서

Adminstration > Diagnostics > Internal Properties의 Edit Internal properties에서 속성을 추가해준다.

teamcity.git.fetch.process.max.memory=1024M

기본이 아마 512M 정도로 잡혀있을 것인데 이를 세팅해주는 것이다.

Edit internal properties가 활성화 되지 않는다면 직접 파일을 로컬에 추가해준다.

<DataPath>/JetBrains\TeamCity\config\internal.properties

해당 폴더에 해당 파일 생성하고 위의 속성 추가 해주면 끝.
