java - Eclipse 删除了我的 3 个项目

Question

我打开了来自 3 个不同项目的一堆文件，我打开了另一个文件以将代码复制到其中，然后我的选项卡突然关闭了。我的 3 个项目的代码完全消失了，每个项目中只有一个空的 gen 文件夹。这是否常见，我可以做些什么来恢复我的代码？

我收到一条错误消息，指出项目是 1.7，需要修复，但显然不是这样。我从未将其更改为 1.7，我尝试修复 android 工具，但没有成功。错误不再出现

当我尝试从本地历史记录恢复时，我看到了该文件，但当我尝试恢复它时，它显示“无法替换资源(结果:状态无效或可能已过期。)。”

我有大约 20 个小时的工作值(value)，所以如果它能恢复就太好了......

我试过重启eclipse，重启我的电脑，都没有用

编辑:我现在收到一个错误:

[2014-02-28 10:08:58 - Chat-Server-Oneway] Project has no project.properties file! Edit the project properties to set one.

您是否查看了实际的工作空间？该项目可以从 eclipse 中删除，但我怀疑工作区是否也被删除了。

转到您工作区的默认位置并查找您的项目。您可以根据需要从那里重新导入它们。
