NetBeans 6.5 IDE 자체에서 NullPointerException이 발생했습니다.

Question

거의 모든 작업 (특히 프로젝트 열기 시도)에 NetBeans를 사용하면 IDE의 오른쪽 하단에 빨간색 빼기 기호가 깜박이기 시작하고 다음과 같은 NullPointerException 오류가 발생합니다. 나는 그것을 클릭한다. 불행히도 공유 컴퓨터 랩 계정을 사용하고 있기 때문에 NetBeans를 다시 설치할 수 없습니다.

저는 vkraemer의 조언을 듣고 ~/.netbeans/6.5 디렉토리의 이름을 변경했습니다. 이제 하나의 프로젝트를 열 수 있지만 다른 프로젝트를 열려고 시도하면 위의 것을 포함하여 4 개의 오류가 발생합니다.

Answer 1

스택 트레이스 프로젝트 서브 시스템에서 제공 : 서버를 추가하려고 또한

다음과 같은 오류가 발생했습니다. 따라서 열린 프로젝트와 관련된 파일 중 하나가 슬픔의 원인입니다.

아마 NetBeans를 다시 설치할 필요가 없습니다. 사용자 디렉토리를 제거해야 할 수도 있습니다.

단계가 매우 쉽습니다.

1. 종료

2. 이 사용자 디렉토리를 찾을 넷빈즈. 그것은 일반적으로 .netbeans/old.6.5

3. 다시 시작 넷빈즈

같은 에 그 디렉토리의 이름을 변경 6.5

4. \ 의 $ HOME /으로 .netbeans/6.5 또는 % USEERPROFILE의 %의으로 .netbeans에 위치한 입니다

5. 프로젝트를 하나씩 다시 엽니 다. 이 오류가 다시 나타나는 경우 프로젝트를 열어 두었으므로 더 많은 조사를 수행 할 수 있습니다.
