我最近将 Eclipse 升级到 Juno 版本，一切似乎都在工作。几周后（现在）我需要在 Android 应用上工作，所以我重新安装了 ADT 插件。它需要更新外部 Android SDK 目录中的一些相关内容。在那之后，一切似乎都很好。
但是，一旦我在模拟器和测试设备上启动应用程序，应用程序就会崩溃。

至关重要的恕我直言，警告“无法解析超类”，然后导致类本身没有被加载。奇怪的是该类存在于 Eclipse 中，它是 RoboGuice 的应用程序类 (http://code.google.com/p/roboguice/) 并且它的 jar 存在。我可以点击它，打开类文件（当然不可读，但是）......
巧合的是我仍然有旧环境（Eclipse Indigo），但由于升级了Android SDK，它需要更新ADT插件，并且有同样的问题。
为什么 RoboGuice 罐子似乎不包括在内有什么建议吗？
