    我目前正在学习Java,它结合了头一本Java图书和Eclipse。直到今晚一切都很顺利!

    当我今晚启动Eclipse时,我看到了一条错误消息,我没有注意到(我知道!我知道!)并确认之后,项目资源管理器是空的,它曾经包含我的头第一个项目!

    在快速“谷歌”之后,我找到了workspace.metadata.log,错误如下所示。

    我使用的Eclipse版本是:20100218-1602,我使用的唯一插件是egit。

    任何帮助都将不胜感激。

    啊,日蚀错误。没有什么能比得上你最重要的工具了,把它拿出来,上帝知道用它来启动你的一天有多恐怖…

    你见过吗? this page? 当我自己诊断Eclipse错误时,我的策略是谷歌搜索“Eclipse”以及我能找到的任何错误消息。上面的链接来自于谷歌搜索:

    "Problems reading information from XML 'OpenTypeHistory.xml'" eclipse

    虽然我确信你现在已经弄清楚了,但肯定有一个文件在某个地方被破坏了。希望这有帮助,我希望你能在不损失任何工作的情况下解决问题。

    上次你正确关闭Eclipse了吗?我将继续创建一个新的工作区,然后在其中导入我的项目文件。最好把时间花在学习上,而不是弄清楚Eclipse出了什么问题:—)

    当然有些文件在Eclipse中被破坏了。甚至我也尝试过Prashant(创建新工作区)给出的解决方案,但不幸的是,这对我来说并不适用。我已经有了日食的副本。所以我重新安装了Eclipse,现在一切正常。最好重新安装Eclipse。

    我在彻底关机后也遇到了同样的问题。从我的工作区备份中复制.metadata目录后,项目将再次出现。
