Eclipse не загрузит рабочее пространство

Я работал в eclipse, и он застрял, а затем он отказался загружать мою обычную папку рабочего пространства

это то, что показывает файл журнала

как я могу снова загрузить эту папку?

ОТВЕТЫ

Ответ 1

У меня была та же проблема. Удалось удалить .metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi. Однако я не уверен в первопричине.

ИЛИ

Переместите содержимое папки "плагинов в другую папку и перезапустите eclipse. Eclipse добавит все эти плагины после перезагрузки. Замените новые папки скопированными папками.

Ответ 2

Удаление файла .snap для меня:

rm WORKSPACE/.metadata/.plugins/org.eclipse.core.resources/.snap

Ответ 3

Просто связав решение, предоставленное Fredrik в потоке: eclipse не запустится, но не отображается ошибка

"Кажется, что он не работает при попытке восстановить рабочее пространство.

Try:

Откройте новое рабочее пространство. Если он настроен на использование значения по умолчанию, перейдите в \configuration.settings\org.eclipse.ui.ide.prefs и установите SHOW_WORKSPACE_SELECTION_DIALOG в true

Попробуйте удалить /.metadata/.plugins/org.eclipse.core.resources/.snap

Как указано в комментарии: если вы используете Eclipse 4, вам может потребоваться удалить файл .metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi, а также.
