sbt cannot find the scripted-sbt dependency

Question

I'm using the scripted sbt plugin for one of my projects and it has been working fine, but stopped working sometime recently for no obvious reason. Here is a sample setup that fails:

# project/plugins.sbt
libraryDependencies += "org.scala-sbt" % "scripted-plugin" % sbtVersion.value

# build.sbt
scalaVersion := "2.11.6"

scriptedSettings

# project/build.properties
sbt.version=0.13.5

When I do sbt update I see the following. Note that it downloads scripted-plugin but cannot find scripted-sbt. This worked fine until recently and just kind of stopped. Any ideas?

Answer 1

It looks like the scripted plugin is only found in the sbt-plugins repository. Which seems to only be added if sbtPlugin is set to true.

Making the following change to your example gives me a resolution:

#build.sbt 
sbtPlugin := true

scalaVersion := "2.11.6"

scriptedSettings

With the following output:

sbt update

Note, I also tried this with sbt 0.13.8 and had the exact same issue and same results.

EDIT: If setting sbtPlugin := true doesn't make sense for this particular application, you can add resolvers += Resolver.typesafeIvyRepo("releases") to the main build.sbt to achieve the same results.

EDIT2: This may also be an issue: resolvers not shared to dependent sbt projects?
