sbt does not resolve Typesafe repository

Question

I have an odd problem with sbt and the Typesafe repository:

[info] Resolving com.typesafe.play#play-json_2.10;2.2.0 ...

sbt.ResolveException: unresolved dependency: com.typesafe.play#play-json_2.10;2.2.0: not found

I can manually download both .pom and .jar from http://repo.typesafe.com/typesafe/releases/com/typesafe/play/play-json_2.10/2.2.0/ so the server is definitely there.

Is this perhaps an sbt problem? Any clues why it would fail if it definitely has the right URL?

Answer 1

It seems there is an unknown problem with the resolver

resolvers += "Typesafe Releases" at "https://repo.typesafe.com/typesafe/releases/"

Finding this question, the problem can be solved by adding yet another resolver:

resolvers += "Typesafe Simple Repository" at
  "http://repo.typesafe.com/typesafe/simple/maven-releases/"

Answer 2

For people facing this issue in 2020 onwards, please replace http part with https in resolver url.
