资源目录不可用 [英] Resource directory is not available

问题描述

Eclipse中显示Problems选项卡，资源目录不可用，尽管事实上它是可用在项目文件夹树：

Eclipse shows in the Problems tab that the resource directory is not available despite the fact it is available in the project folders tree :

[2012-09-11 12:14:43 - QR01] ERROR: resource directory 'D:\workspaceQR\QR01\res' 
does not exist

我试图通过重建的路径来解决这个错误，我不能设法解决它，并它给我的项目名称旁边的红色exclaimation大关。
任何建议，为什么Eclipse的说，我的资源目录不可？

I tried to fix this error by rebuilding the path and I couldn't manage to solve it and also it gives me red exclaimation mark beside the project name. Any suggestion why Eclipse says that my resource directory is not available?

获得此为好，问题就解决了​​。

For future reference: This error could manifest when upgrading to SDK Tools r22. After updating, you need to reopen the SDK Manager. Here you would find a new package - Android SDK Build-tools. Get this as well, and problem solved.
