【问题描述】：
真的经历了一场噩梦，试图与一个带有 Facebook 的 android 项目合作。噩梦是它的工作，然后我一定触摸了我的一个 XML，现在 Eclipse 真的有床了。我什么都不能运行。
所以我缩小了一点。我的项目可怕地缺少 R 文件。清洁无济于事。当我尝试添加 com.example.packagename.R 的导入时，它不知道我在说什么。当我尝试运行我的项目时：

然后一百万个错误涉及这些罐子。我不知道如何修复这些罐子。我担心我永远不会修复它们。我想下载另一个编辑器并从头开始，但我不确定这是否可以恢复。
当我尝试构建 appcombat_v7 时，它不会构建。我在它需要的 1 个文件中得到一个模糊的错误。 res/values/values-large-v14/themes_base.xml。一些找不到的资源。
如何修复这些罐子？我在 Eclipse 中……Android Studio 是否会时不时地爆炸？

@peter.petrov 感谢您的诚实。这样浪费的时间少了。

这个问题真是一团糟。似乎没有人真正有一个像样的解决方案。前几天我也碰巧在这上面花了 4-5 个小时，所有建议的“解决方案”都没有任何意义（问题本身也没有）。只需从头开始重新创建您的项目，看看是否有帮助。

你为什么使用jar而不是通过Maven导入它们？
