在将Linux工作空间迁移到Windows时遇到的错误：无法写入.classpath文件。通过取消隐藏该文件的隐藏属性，解决了无法读取的问题。此经验适用于在不同操作系统间迁移开发环境。

The cause was copying a workspace from Linux to Windows. The windows hidden attribute is set on the .classpath file. Removing this attribute fixes the error.


右键点击.classpath文件，查看属性肯定被你隐藏了，取消隐藏就可以读取了

1. .classpath文件的属性去掉隐藏 2.  workspace 中  删除import进来的项目，重新import 3.   build  1)  选择build path--->configure build path; 2)  删除JRE System Libreary[jre1.6.0_05](unbound) 错误 3)  重新添加JRE

该情况一般出现在导入别人的项目的时候 修改build path 中的 jdk时出现 该错误 解决方案： 解决方法1： 原因是这文件被修改成了隐藏，只要取消隐藏就可以保存了。 如何显示隐藏文件呢？ 首先打开"我的电脑",如果有打开一窗口,就跳过这一步 点击查看,打开查看选项 点击打开右边的选项 选择第二选项页"查看" 取消勾选"显示隐藏的文件.文件夹和驱动器",点击确定就可查看隐藏文件 ...
