sbt - 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？

Question

我尝试在没有互联网连接的区域中处理我的项目。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)。

*

My question is: how to ensure that when i have the connection, sbt fetches the libs in the cache ONCE, so that when i don't have it, it fetches all my local repo including the one of maven.

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 从 maven 缓存下载时遇到问题

sbt 可以在 ivy local

中找到我的大部分依赖项

由于某些原因，sbt 找不到某些特定的依赖项，
显然没有缓存。

例如，这里是 sbt 应该已经缓存的库的踪迹。

这是缓存内容:

/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 jar 里，你发现 jar 被拿来了。

例如

在辅助注入(inject)的 jars 文件夹中，您有:

guice-assistedinject-4.0-beta4.jar

它的ivy.xml如下:

Answer 1

见 Caching and Configuration .

When offline := true, remote SNAPSHOTs will not be updated by a resolution, even an explicitly requested update. This should effectively support working without a connection to remote repositories. Reproducible examples demonstrating otherwise are appreciated. Obviously, update must have successfully run before going offline.
