那些遇到过的问题

eclipse不会加载工作区

Len*_*Bru 27 eclipse workspace

我在eclipse工作,它被卡住了,接下来它拒绝加载我常用的工作区文件夹

这是日志文件显示的内容

我怎么能再次加载这个文件夹？

我有同样的问题.正在删除.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi.不过,我不确定根本原因.

要么

将"plugins"文件夹的内容移动到其他文件夹并重启eclipse.Eclipse将在重新启动后添加所有这些插件.用复制的文件夹替换新文件夹.

  • 删除元数据迫使我重新安装所有插件,并重做快捷方式 - 但是,将元数据移动到外部文件夹,打开文件夹然后恢复元数据就行了! (3认同)
  • 我应该睡一觉,花了几分钟才能看出.metadata目录在工作区dir本身 (3认同)

删除.snap文件对我有用:

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

只需链接Fredrik在线程中提供的解决方案:eclipse将无法启动,但不会显示错误

"尝试恢复工作区时似乎失败了.

尝试:

打开一个新工作区.如果已将其设置为使用默认值,请转至\ configuration.settings\org.eclipse.ui.ide.prefs并将SHOW_WORKSPACE_SELECTION_DIALOG设置为true

尝试删除/.metadata/.plugins/org.eclipse.core.resources/.snap

正如评论中所建议的那样:如果使用Eclipse 4,您可能必须删除.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi文件."
