Download Artifacts from ivy repository fails

[Paththamestrige Perera]

Hello All,

I'm a new user to Apache Archiva and I'm currently setting up Archiva 2.2.0
to manage asa remote proxy server for an application built with sbt.
I have added https://repo.typesafe.com/typesafe/ivy-releases/ as a remote
repository in Archiva but my sbt build fails with following messages:

[debug] local: no ivy file found for org.scala-lang#scala-compiler;2.10.4
[debug] tried
http://localhost:8080/internal/org.scala-lang/scala-compiler/2.10.4/ivys/ivy.xml
[debug] CLIENT ERROR: Not Found url=

[debug] my-ivy-proxy-releases: no ivy file found for

[debug] tried
http://localhost:8080/repository/internal/org/scala-lang/scala-compiler/2.10.4/scala-compiler-2.10.4.pom

Also from Archiva side, I see following logs:

[08/Feb/2016:17:50:59 +0000] "HEAD
/internal/org.scala-lang/scala-compiler/2.10.4/ivys/ivy.xml HTTP/1.1" 404
1423 "-" "Apache Ivy/2.3.0"

I can't figure out why these artifacts are not downloaded. When I try
accessing them directly,
they are available at https://repo.typesafe.com/typesafe/ivy-releases/
Can someone enlighten me on this problem ?

Thanks!
