你用的是什么操作系统?我使用Linux Mint。在我的例子中，结果是一个符号链接问题。每次我尝试用符号链接路径创建项目时，它都会给我这个错误。在其他地方创建项目，然后将其迁移到符号链接目录，为我解决了这个问题。

这个选项解决了我的问题。

Suppose you have something like: /prj/workspace/prj1 /prj/workspace/prj2 And your eclipse workspace is in /prj/workspace level (i.e. /prj/workspace/.metadata). If you're having problem importing prj1 and prj2, you can either move your .metadata somewhere else (/prj/.metadata, /prj/eclipse/.metadata, etc.) or create a sub level in workspace so that it looks like: /prj/workspace/android/prj1 /prj/workspace/android/prj2 And import prj1 and prj2 again. In another word: as long as prj1, prj2, and .metadata are not in the same level it will be fine.

今天我意外地解决了这个问题:

以下2个步骤可能不涉及，但不确定:

从(Eclipse菜单)调用*“/Window/Android SDK Manager”并更新a)“Android SDK Tools”“Android SDK平台工具”包 从Eclipse菜单“/Help/Check for Updates”调用并更新Eclipse。重新启动Eclipse。

以下步骤是必要的:

From eclipse menu "/File/Import/Android/Existing Android Code Into Workspace" Browse and select problematic project/or problematic projectS parent directory. Check "Copy projects into workspace". Check "Add projects into working sets". Press finish. [Optional scenario]: If project(s) and their containing folders have been renamed with the fully qualified package names then simply click on project node parent (where you see project package name instead of project's old name) in Eclipse and rename project with old name. Eclipse will rename folder too.

附注:在日蚀朱诺号上测试过。

Edit: Many times have passed since this answer and new Eclipse and Android SDK arrived. They have no much more problems during importing existing projects. The only thing one has to consider before importing is to move project folders(those ones one is willing to import) outside of eclipse workspace dir and then check checkboxes ("copy projects into working sets", "add projects into wokring sets") in import wizard dialog. Also I recommend doing this with latest Android SDK because it no more imports projects with dummy names and does not rename folders as it did in some custom cases.

将项目源代码和支持库粘贴到任何其他新创建的文件夹中，并尝试从那里导入。这对我很管用。

复制项目到你的工作空间，从eclipse文件>新建>项目创建新的Android应用程序项目，瞧。
