Why does build fail with sbt.ResolveException: unresolved dependency: com.typesafe.sbt#sbt-pgp;0.8.2: not found?

Question

We are suddenly getting failures on the build server (typesafe and maven repos are proxied through our internal Nexus repo) for a project that successfully built with sbt 0.13.5 (tried upgrading to 0.13.6, still not working) Any ideas? EDIT: note, works fine when run locally

Answer 1

It appears they've moved to Bintray recently (and perhaps cleaning up other locations?).

With the recent release of sbt-pgp 1.0-M1 I can find the plugin's binaries at https://bintray.com/sbt/sbt-plugin-releases/sbt-pgp/1.0-M1/view.

As you can read in Improvements in 0.13.6 Release Notes:

Adds Resolver.jcenterRepo and Resolver.bintrayRepo(owner, repo) to add Bintray easier.

With all that said, the following worked for me (mind I haven't worked with the plugin before):

project/sbt-pgp.sbt

resolvers += Resolver.jcenterRepo

addSbtPlugin("com.typesafe.sbt" % "sbt-pgp" % "1.0-M1")

project/build.properties

sbt.version=0.13.6

No other files were needed to boot sbt shell (with sbt) and query for available plugins:
