JFace 플러그인을 호출 할 때 이클립스 null 포인터 예외가 발생합니다.

Question

CentOS에서 화성을 Eclipse에 설치했기 때문에 프로젝트 환경의 "java build path", "deployment assembly", "project facets"및 일부 다른 탭에 연결할 수 없습니다. Problems occurred after invoking code from plug-in "org.eclipse.jface". 오류 창이 나타나서 자세한 스크린 샷을 첨부했습니다. 나는 프로젝트를 청소하고, 작업 공간을 전환하고, 새 프로젝트를 만들고, .classpath, .project 및 .settings를 제거하고, Eclipse를 clean - clean IDE 설치, JDK 변경 등의 많은 솔루션을 검색 및 시도했지만 아무 것도 작동하지 않았습니다. 지금까지. 누가 이길 거니?

EDIT2 : 도움을 주셔서 감사합니다 여러분. 내가 해결 한 방법 : @howgler와 같은 일식 업데이트, 새로운 작업 공간으로 가져 오기 및 모든 프로젝트 정리. 필요한 경우 다른 작업 공간으로 가져옵니다. 이전 버전의 작업 공간은 버전 차이로 인해 변경 될 수 있으므로 백업하는 것을 잊지 마십시오.

Answer 1

known bug은 Eclipse Oxygen.0 (4.7.0)에서 수정되었습니다.

update 더 이상 유지되지 않는 Eclipse Mars (4.5) 에서 Eclipse Oxygen (4.7)으로 문제를 해결해야합니다.
