In my situation, I cannot access internet in my office linux server. Therefore, I installed sbt in my personal computer. I followed instructions on sbt official web-site and run/compile a "hello world" for getting all dependency data.
Then, I copied ~/.ivy2 and ~/.sbt and sbt bin folders to my offline office desktop. But when I run sbt, I got these errors:
[info] welcome to sbt 1.4.9 (Oracle Corporation Java 1.8.0_25)
[info] loading project definition from /proj/mtk07847/test/scala/project
[info] Updating
[info] Resolved dependencies

[warn] Note: Unresolved dependencies path:
[error] sbt.librarymanagement.ResolveException: Error downloading org.scala-lang:scala-library:2.12.12

[error] download error: Caught java.net.SocketException: Connection reset (Connection reset) while downloading https://repo1.maven.org/maven2/org/s

...
It seems that sbt tried to download missing scala-library:2.12.12 which I already prepared. In my ~/.ivy2 folder，the structure and path looks like the following:
~/.ivy2/cache/org.scala-lang/scala-library/jars/scala-library-2.12.12.jar
~/.ivy2/cache/org.scala-lang/scala-library/ivy-2.12.12.xml
~/.ivy2/cache/org.scala-lang/scala-library/ivy-2.12.12.xml.original
~/.ivy2/cache/org.scala-lang/scala-library/ivydata-2.12.12.properties
which is different from above messages:
[error] not found: ~/.ivy2/localorg.scala-lang/scala-library/2.12.12/ivys/ivy.xml
should I modified any describing files to indicate searching path or rule for sbt? or this method is totally wrong (if so, can anyone know the flow guide me the better way?)
