如何设置sbt,以便在线时抓取所有必要的依赖项,让我离线工作呢？

Question

我尝试在没有互联网连接区域的情况下处理我的项目.令我惊讶的是,在这种情况下,sbt遇到了麻烦.虽然,我应该将我的库放在缓存中(鉴于我最初在线启动项目),sbt无法解决某些依赖关系.

Sbt无法获取我的本地maven存储库,也无法找到我认为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获取缓存ONCE中的libs,这样当我没有它时,它会获取我的所有本地仓库,包括maven.

我问这个是因为我对当前情况的理解(即没有互联网连接时):

1. sbt从maven缓存下载时遇到问题
2. sbt可以找到我在ivy local中的大多数依赖
3. sbt找不到某些特定的依赖,由于某些原因,显然没有缓存.

例如,这里有sbt应该已经缓存的一些libs.

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个文件夹另外包含:

一个罐子,src和docs文件夹.在罐子里,你会发现罐子被拿走了.

例如

在辅助注射的jars文件夹中,您有:

吉斯 - assistedinject-4.0-beta4.jar

它的ivy.xml如下:

请参阅缓存和配置。

当 时offline := true，远程快照将不会通过解决方案进行更新，即使是明确请求的更新也是如此。这应该可以有效地支持在没有连接到远程存储库的情况下进行工作。赞赏以其他方式证明的可重复示例。显然，更新必须在离线之前成功运行。
