Sbt Error retrieving required libraries

问题

I tried updating sbt to 0.13.15, and now whenever i try to run sbt i get the following error. I'm not behind any proxy and the .pom link mentioned in the error downloads without a problem in the browser. Before upgrade sbt 0.13.7 worked without any problem for me. I'm on windows 10.

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0
Getting org.scala-sbt sbt 0.13.15  (this may take some time)...

You should only need to create a .sbt\repositories file if you're doing something special (such as using a local artifact server, such as Nexus or Artifactory). Maybe your installation went a little awry? Try creating this file (C:\Users\Kamil\.sbt\repositories) with the following contents, then retry your build.

[repositories]
  local
  sbt-releases-repo: http://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]
  sbt-plugins-repo: http://repo.scala-sbt.org/scalasbt/sbt-plugin-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]
