C ++ Eclipse Luna CDT — исключение java.lang.NullPointerException
ОБНОВИТЬ:
Кажется, это только мой проект Event_Creator, который имеет эту проблему. Все мои другие проекты могут быть скомпилированы и успешно запущены.
Обновление 2:
Когда я хочу собрать свой проект, я могу выбрать только сборку «по умолчанию», обычно я должен видеть отладку и выпуск. Итак, я думаю, что-то не так с моими настройками сборки для проекта?
У меня проблема с eclipse luna, когда я пытаюсь построить свой проект, я получаю эту ошибку:
Ошибки произошли во время сборки.
Ошибки запуска компоновщика ‘CDT Builder’ в проекте ‘Event_Creator’.
Внутренняя ошибка построения проекта Конфигурация Event_Creator По умолчанию
java.lang.NullPointerException
Внутренняя ошибка построения проекта Конфигурация Event_Creator По умолчанию
java.lang.NullPointerException
Event_Creator был моей программой тогда.
Я понятия не имею, что на самом деле вызывает это, я программировал на эту программу около 2 недель, и я смог скомпилировать ее просто отлично, но сегодня это только что произошло.
Я перепробовал кучу вещей, даже убрал затмение, а затем снова загрузил его. Я также попытался создать новые рабочие пространства, чтобы увидеть, было ли что-то не так с моей текущей, но у меня все еще была та же проблема.
Я также использую рабочее пространство C / C ++, так что я на самом деле не использую какое-то странное рабочее пространство java, которое может испортить мне жизнь.
Я использую компилятор minGw и этот репозиторий CDT:
http://download.eclipse.org/tools/cdt/releases/8.6/
И напоминание, я смог нормально скомпилировать две недели, это случилось сегодня, когда я запустил свой компьютер и открыл затмение.
Внутри моего файла .log в \ Eclipse \ Workspaces.metadata я обнаружил эти записи, связанные с ошибкой нулевого указателя, хотя я понятия не имею, что они на самом деле означают.

Решение
Хорошо, так как я заметил, что у проекта Event_Creator есть только опция сборки «по умолчанию», в то время как другие мои проекты (которые я мог собрать) имели опцию «отладка» и «выпуск», я просто создал новый пустой проект и вручную переместил свои файлы в этот проект Затем я открыл затмение, обновил свой новый проект и вуаля, я мог его построить.
Я предполагаю, что что-то случилось с файлом проекта в старом каталоге, что повредило мою сборку.
