在私有git repo上引用sbt构建失败

我决定在多个git存储库上拆分一个巨大的sbt多模块项目。所有存储库都托管在私有repo中。

当我用这样的台词 build.sbt 以下内容:

lazy val common = ProjectRef(uri("git://github.com:PRIVATE-ORG/akka-common.git"), "akka-common")

SBT抛出错误:

fatal: Unable to look up github.com:PRIVATE-ORG (port 9418) (nodename nor servname provided, or not known)

我尝试在本地计算机上运行sbt构建,在本地计算机上我可以访问这些私有repo。

更新

我试图改变一个协议:

lazy val common = ProjectRef(uri("ssh://git@github.com:PRIVATE-ORG/akka-common.git"), "akka-common")

错误已更改:

fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

如何处理这个问题?
