我尝试在我的项目上工作，而在一个没有互联网连接的区域。令我惊讶的是，她在那种情况下遇到了麻烦。虽然，我应该在缓存中有我的库(考虑到我最初在线启动项目)，但sbt无法解决一些依赖关系。
Sbt不能获取我的本地maven存储库，他也不能找到一些其他依赖，我认为他已经下载(即在缓存中)。
*我的问题是:如何确保当我有连接，sbt在缓存中获取库一次，所以当我没有它，它获取包括maven在内的所有本地repo。
我问这个问题是因为我对当前情况的理解(即当没有互联网连接可用时):
- sbt从maven缓存下载有问题
- sbt不能找到一些特定的依赖，由于某些原因，
例如，下面是sbt应该已经缓存的库的跟踪。
