Eclipse Error: 'Setting build path' has encountered error
提问by Anand
I am using an API called jtwitter. It has a single jar file jtwitter.jar I have been working with it and maintained it using git. I hosted the code in github. For somedays, i have not touched its code. Today, when i cloned my git repo (actually my system got a crash some days back so I had to clone ) and loaded the project into eclipse. Now when i wanted to add the jtwitter.jar into the buildpath, the following error occurs.
我正在使用一个名为 jtwitter 的 API。它有一个 jar 文件 jtwitter.jar 我一直在使用它并使用 git 维护它。我在github中托管了代码。有几天，我没有接触过它的代码。今天，当我克隆我的 git 存储库时（实际上我的系统几天前崩溃了，所以我不得不克隆）并将项目加载到 eclipse 中。现在，当我想将 jtwitter.jar 添加到构建路径中时，会发生以下错误。
I am giving the partial exception stack trace here
我在这里给出部分异常堆栈跟踪

Make sure that the directory and file are still there, take a look at D:\workspace\ltwitter is a valid path, has a .classpath file and it is readable. Try opening .classpath in Notepad for a test of readability.
确保目录和文件仍然存在，看看 D:\workspace\ltwitter 是一个有效路径，有一个 .classpath 文件并且它是可读的。尝试在记事本中打开 .classpath 以测试可读性。

Does D:\workspace\ltwitter\exist? Do you have access to it? Is this where the project lies?
是否D:\workspace\ltwitter\存在？你可以访问它吗？这是项目所在的地方吗？
You can fix the build path using the context menu of the project -> Build Path -> Configure Build Path. There you can see all entries, the ones which are not valid are marked as such.
您可以使用项目的上下文菜单 -> Build Path -> Configure Build Path 来修复构建路径。在那里你可以看到所有条目，无效的条目被标记为这样。

Check directory permissions on D:\workspace\ltwitterand file permissions on D:\workspace\ltwitter\.classpath.
检查 上的目录权限D:\workspace\ltwitter和 上的文件权限D:\workspace\ltwitter\.classpath。
File Properties->Security tab in Windows Explorer
Windows 资源管理器中的文件属性-> 安全选项卡

Assuming the directory exist and has the proper authorization, check also your logs for missing properties during eclipse launch (see this thread)
假设该目录存在并具有适当的授权，请在 eclipse 启动期间检查您的日志是否缺少属性（请参阅此线程）
If you find some missing properties, try this eclipse.ini
如果你发现一些缺失的属性，试试这个 eclipse.ini

I had the same problem, and I found out it was because the .classpathfile was hidden. Removing the hidden attribute resolved the issue.
我遇到了同样的问题，我发现这是因为.classpath文件被隐藏了。删除隐藏属性解决了这个问题。
