我正在将Facebook SDK用于一个Android项目，并且在将support-v4库编译到我的项目时遇到问题。我得到的错误是:Could not find com.android.support:support-v4:13.0.0
我已经使用SDK安装了Android支持存储库。
令我感到困扰的是，似乎gradle不会尝试使用本地Maven存储库进行查找。在工作机器上运行gradlew.bat assembleDebug --debug时，我得到:

在不工作的计算机上，我得到:

最佳答案
事实证明，ANDROID_HOME路径不正确。我以为是:ANDROID_HOME=C:\adt-bundle-windows-x86_64-20140702\adt-bundle-windows-x86_64-20140702\sdk
但实际上是:ANDROID_HOME=C:\adt-bundle-windows-x86_64-20140702\adt-bundle-windows-x86_64-20140702\sdk\tools
一旦我关闭了当前的命令提示符并打开了一个新的提示符，它就可以正常工作。
