I would recommend to wipe out all the eclipse related configuration files(make sure you take the backup if you have manually made some changes in those) and import the project again, by following

File -> Import... -> Existing Project into Workspace

Make sure you take the backup of whole project before doing this.

blocks|key|3613324|text|当Eclipse陷入某种模糊状态时，我通常会发现在工作区目录中重新创建.metadata文件夹很有用。这是一个激烈的解决办法，但它通常对我有效。之后，您可以重新导入所有项目。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3613325|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

When Eclipse gets stuck in some obscure status, I usually find useful to recreate the .metadata folder in workspace directory. It is a drastic solution, but it usually works for me. After that you can reimport all your projects.

blocks|key|4493998|text|这种情况发生在我身上，因为我的.project文件中有冲突。我在一个文本编辑器中打开它，修复了冲突(在我的例子中，从====...移到>>>branch...，以及<<<HEAD)，然后我能够在eclipse中打开这个项目。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4493999|entityMap^0|1M|7|1V|C|2A|7|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|O|8|@]|D|@]|E|$]]]|G|$]]

This happened to me because I had a conflict in my .project file. I opened it up in a text editor and fixed the conflict (in my case, removed from <code>====...</code> to <code>&gt;&gt;&gt;branch...</code>, as well as <code>&lt;&lt;&lt;HEAD</code>) and then I was able to open the project in eclipse.

blocks|key|3613424|text|我刚刚遇到了同样的问题(使用构建在Eclipse上的Zend+12+)。我的问题是，我正在从远程服务器创建一个项目，而我只是下载所有东西，其中还包括旧项目中的.project文件。直到我关闭程序并试图再次打开它(通常直到第二天)，它才会显示这个错误。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3613425|我似乎是通过确保在初始化项目时不下载.project来解决这个问题的。|3613426|entityMap^0|27|8|0|I|8|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|P|8|@]|D|@]|E|$]]]|I|$]]

I was just encountering this same issue (using Zend Studio 12, which is built on Eclipse). My problem was that I was creating a project from a Remote Server, and I was just downloading everything, which also included the <code>.project</code> file from the old project. It wasn't showing this error until I'd closed the program and tried to open it again (which usually wasn't until the next day).

I seem to have resolved it by making sure not to download the <code>.project</code> when initializing the project.

blocks|key|3613236|text|如果.project文件是文本文件，那么如果您将其置于版本控制中，则可能需要从那里复制它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3613237|在尝试以下操作之前，请对当前项目状态进行备份。|3613238|假设您没有旧的副本，您可以在文本编辑器中打开它，并尝试查看是否有明显的错误。|3613239|如果失败，将项目的源文件复制到一个新位置(没有eclipse配置文件)，并将其作为一个新项目导入eclipse。|3613240|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

If the .project file is a text file, so if you have it in version control you might want to copy it over from there.

Before you trying the following make a backup of your current project state.

Assuming you don't have an old copy, you can open it in a text editor and try to see if there is something obvious wrong.

If this fails, copy the source files of your project to a fresh location (without the eclipse configuration files) and import it as a new project into eclipse.

blocks|key|4493872|text|如果您仍然拥有所有其他源文件(.java文件、AndroidManifest.xml、资源)，那么您可以通过简单地转到包含该项目的文件夹，删除您认为现在为空的.project文件，然后使用新的项目向导从现有的源代码树中为您重新创建项目(和.project文件)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4493873|从菜单中选择File+->+New.->+Project，然后在第一个对话框中，从现有代码中选择Android。|offset|length|style|BOLD|4493874|如果您对.project做了什么特别的事情(依赖于特定的.jar文件或对类路径的更改)，那么在您重新创建项目之后，您可能不得不重新执行这些步骤；但是至少它应该会恢复您已经拥有的代码。|4493875|entityMap^0|0|6|M|1C|8|0|0|2J|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]|$D|P|E|Q|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|R|8|@$D|S|E|T|F|G]]|9|@]|A|$]]|$1|J|3|-4|5|6|7|U|8|@]|9|@]|A|$]]]|K|$]]

if you still have all of your other source (.java files, AndroidManifest.xml, resources), you might be able to get your project back by simply going to the folder containing the project, removing the .project file that you say is now empty, and then using the new project wizard to recreate the project (and .project file) for you from your existing tree of source.

from the menus, select File -> New... -> Project , and then, in the first dialog, choose Android Project from Existing Code .

if you had done anything special to the .project (reliance on specific .jar files or changes to classpath), you may have to re-do these steps after you re-create your project; but at least it should pick up the code you already have.

blocks|key|3613416|text|如果所有的文件都是空的，而且你没有工作备份，我无能为力。我建议在将来使用适当的版本控制。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3613417|使用git或mercurial，它们有很好的UI集成(参见tortoisegit/tortoisehg)。|3613418|要将构建过程和库管理与eclipse分离开来，请看一下maven或gradle，这可能会在未来的项目中有所帮助。|3613419|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

If all the files are empty, and you have no working Backup, I can't help. I would recommend to use proper version control in the future.

Use git or mercurial, they have nice UI integrations (see tortoisegit/tortoisehg).

To decouple the build process and library management from eclipse, take a look at maven or gradle, this might help you in future projects.

blocks|key|3613495|text|我在Eclipse中也遇到了同样的问题，但真正的问题是，我将实际的Source项目文件夹从源位置(+eclipse试图从源位置获取项目)移到其他地方，因此eclipse无法获得web.xml文件，因为它是不可用的。现在，我将源项目文件夹位置更改为eclipse试图搜索的路径。问题为我解决了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3613496|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I also got the Same Issue in Eclipse but the real problem is i removed the actual Source project folder from source location (from which eclipse is trying to take the project) to some other place hence my eclipse is unable to get web.xml file since it is not available. Now i changed my source project folder location to the path where eclipse is trying to search for. Issue Resolved for me.

blocks|key|3637094|text|只需删除工作区中的“servers”文件夹，然后再试一次。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3637095|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Just delete the 'servers' folder in your workspace and try again.

I think Eclipse is trying to make me miserable. A couple of hours ago, my project was working and compiling well. Suddenly that all changed. Eclipse somehow wipes out all changes I have made to my files(activity, manifest etc.) I make sure to save often but when I go to run the project, I get the error that I have a build error. I checked and there was none, so I go to close Eclipse, so I can reopen and see if the errors will go away. Instead what happens is Eclipse wipes clean all my files and I end up with a project on disk with lots of blank code files. I try to run anyway, and I get the error message below. 

Failed to read the project description file (.project) for 'com.example.android.nfc.simulator.FakeTagsActivity.FakeTagsActivity'. The file has been changed on disk, and it now contains invalid information. The project will not function properly until the description file is restored to a valid state.

Anyone have an idea what in the world this is about and how I can rectify this?

Eclipse Hell . . . Failed to read the project description file (.project)

我觉得Eclipse是想让我痛苦。几个小时前，我的项目运行良好，编译也很好。突然之间一切都变了。Eclipse以某种方式抹掉了我对我的文件(活动、清单等)所做的所有更改。我确保经常保存，但当我去运行项目时，我会得到一个错误，我有一个构建错误。我检查了，没有发现，所以我去关闭Eclipse，这样我就可以重新打开并查看错误是否会消失。相反，Eclipse擦除了我的所有文件，最后我在磁盘上得到了一个项目
