【中文标题】如何设置 sbt 以便在联机时获取所有必要的依赖项，然后让我脱机工作？

【英文标题】：How to set up sbt so it grabs all necessary dependencies when online and let me work offline then?

【问题描述】：

我尝试在没有互联网连接的区域处理我的项目。令我惊讶的是，sbt 在这种情况下遇到了麻烦。虽然，我应该将我的库放在缓存中（鉴于我最初是在线启动项目的），但 sbt 无法解决一些依赖关系。

Sbt 无法获取我的本地 maven 存储库，他也找不到我认为他已经下载的其他依赖项（即在缓存中）。

*

我的问题是：如何确保当我有连接时，sbt 一次获取缓存中的库，这样当我没有它时，它 获取我所有的本地 repo，包括 maven 的一个。

我问这个是因为根据我对当前情况的理解（即没有可用的互联网连接时）：

sbt 无法从 maven 缓存下载 sbt 可以在 ivy local 中找到我的大部分依赖项 sbt 找不到某些特定的依赖项，由于某些原因， 显然没有缓存。

例如，这里是 sbt 应该已经缓存的库的踪迹。

这里是缓存内容：

/Users/maatary/.ivy2/cache/com.google.inject.extensions

extensions-parent guice-assistedinject guice-multibindings

您在每个文件夹中的位置：

ivy-4.0-beta4.xml ivydata-4.0-beta4.properties ivy-4.0-beta4.xml.original

其他最后 2 个文件夹还包含：

一个 jars、src 和 docs 文件夹。在罐子里，你会找到取出的罐子。

例如

在辅助注入的 jars 文件夹中，您有：

guice-assistedinject-4.0-beta4.jar

【问题讨论】：

sbt 的版本是多少？ guice-assistedinject 和 guice-multibindings 在 /Users/maatary/.ivy2/local/com.google.inject.extensions/ 下吗？你能列出他们的内容吗？

它们不在本地，而是在缓存中。我没有发布那些库

我们正在研究这个用例。现在，我们如何为此挂钩 ivy 存在一些微妙的问题。

Working offline with SBT and SNAPSHOT dependencies的可能重复

【参考方案1】：

见Caching and Configuration。

当offline := true 时，远程快照将不会被分辨率更新，即使是明确请求的更新。这应该有效地支持在没有连接到远程存储库的情况下工作。以其他方式证明的可重复示例受到赞赏。显然，更新必须在离线之前成功运行。

此功能可能适合您，也可能不适合您，但它旨在解决您的情况。 试试看，如果不行，请在 Github 上提出问题。

【讨论】：

它在某些情况下可能会起作用（？），但如果我进行清洁，那么它肯定不会起作用
