日食。保存工作区需要永远

Question

我的问题是，在关闭日食之后，即使在两个小时之后，保存工作区也没有完成，让我无法在日食上做任何事情。我签到了 C：.. \ workspace.metadata.log，错误是：

!ENTRY org.eclipse.jdt.ui 4 10001 2016-12-25 12:51:13.037

问题是我不知道如何在不打开eclipse的情况下修复它（我不能因为它的保存工作区）。

我会很乐意帮助你。

PS。对不起我的英语，我不是母语。

Answer 1

在Eclipse的顶层菜单中，转到窗口菜单

1. Windows菜单 - ＆gt;偏好 - ＆gt;一般（扩展） - ＆gt;工作区 （点击它）。
2. 查找“文本文件编码”框。默认是 “的Cp1252“。
3. 更改收音机以选择其他并从组合中选择“UTF-8” 框。



设置此UTF-8编码后，您可以在代码中使用UTF-8。现在你不会得到'CP1252字符编码'错误。
