I can't try any example from spay.io since I can't resolve an error about dependencies in build.sbt. Here is how it looks like:
//....skipped
resolvers += "spray repo" at "http://repo.spray.io"
libraryDependencies += "io.spray" % "spray-can" % "1.0"
It gives me an error, however:

Even when I change the version to be 1.1, I still have the same error.
What's wrong with that?
There is no version 1.0 of spray yet, according to the docs (and browsing the repo): see spray - Current Versions.
The latest seems to be either 1.0-M7 for scala 2.9.2 or 1.1-M7 for scala 2.10.0-RC5.

I've started to learn Scala recently for machine learning purpose and i need plotly to draw my plots.
The fact is after following all installation

version := "1.1.0"
scalaVersion := "2.12.4"
libraryDependencies += "co.theasi" %% "plotly" % "0.2.0"
I tried to downgrade my sbt version and another ploty version, but it didn't work.
This is the exact library dependency:
libraryDependencies += "co.theasi" % "plotly_2.11" % "0.2.0"
in your code sbt is trying to look for plotly dependency for scala version 2.12, which I guess is not available. As while going through there documentation, it looks that the latest version supports scala 2.11.

I am trying to use scala parser combinators in my scala project.
The only .sbt file I have in my project is project/build.sbt:
libraryDependencies += "org.scala-lang.modules" %% "scala-parser-combinators" % "1.0.4"
I tried adding this line to build/project.sbt
resolvers += "Typesafe Repo" at "http://repo.typesafe.com/typesafe/releases/"
but I get the exact same error.
When I execute sbt from the terminal in the root directory of my project I obtain the following dependency error (those are the last lines before the error):

To write my project/build.sbt file I followed the directive given by the github repository of the scala parser combinators.
Of course when I do not specify anything in project/build.sbt I get compile time errors from sbt which does not understand where the Parser classes source files are.
Would there be any in which I could configure project/build.sbt so that I can use Scala's parser combinators library?
Based on this part of the error:
[warn] Note: Unresolved dependencies path:
[warn] org.scala-lang.modules:scala-parser-combinators_2.10:1.0.4
^
It looks like you're using Scala 2.10, where parser combinators are part of the standard library. They were split from the standard library as of Scala 2.11, so the jar you're looking for doesn't exist. If you're sticking with 2.10, simply remove that dependency, you'll get it in the standard library.
I have an odd problem with sbt and the Typesafe repository:

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

I recently started a new project with the Play! Framework and Scala.
I'm used to using Squeryl for my ORM, but for some reason it cannot resolve my dependency this time (Although it will resolve others, just not squeryl).
The only thing I'm doing differently is that I'm on a different computer than I was before (Windows now, Arch before) and I'm using Play 2.1.1 instead of 2.1.
EDIT: I am also behind a proxy, I thought this may have been resolved since I can resolve some dependencies, but I can't see any other reason than the proxy is screwing with sbt. I can see the maven repo for squeryl in my browser, but sbt fails to find it.
build.properties:
sbt.version=0.12.2
Build.scala:
val appDependencies = Seq(
// Add your project dependencies here,
jdbc,
"org.squeryl" %% "squeryl" % "0.9.5-6"
)
plugins.sbt:
// Comment to get more information during initialization
logLevel := Level.Warn
// The Typesafe repository
resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"
// Use the Play sbt plugin for Play projects
addSbtPlugin("play" % "sbt-plugin" % "2.1.1")

When you see http://repo1.maven.org/maven2/org/squeryl/
you will get solution.
PROJECT/project/Build.scala
val appDependencies = Seq(
// Add your project dependencies here,
jdbc,
anorm,
"org.squeryl" % "squeryl_2.10" % "0.9.5-6"
)
This is from my build.sbt (well, a relevant section) - what scala version?
scalaVersion := "2.10.1"
resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases"
libraryDependencies ++= Seq(
"org.squeryl" %% "squeryl" % "0.9.5-6",
To be sure that it's not a potential SBT project's configuration issue, don't use for now the %% notation. Indeed, this one automatically chooses the Jar version corresponding to your current scala version, which may be different than the one you expect (oversight in your conf, conflict of variables in some configuration files etc...).
Prefer this in order to isolate your "error" context:
libraryDependencies += "org.squeryl" % "squeryl" % "0.9.5-6"
It ended up being an issue with my proxy at work, it was setup wrong and had to correct it. All is well now!
I use playframework and here is my appDependencies in Build.scala:
val appDependencies = Seq(
// Add your project dependencies here,
jdbc,
anorm,
"com.rabbitmq" % "amqp-client" % "3.0.1",
"com.typesafe.akka" %% "akka-agent" % "2.1.0",
"org.mongodb" %% "casbah" % "2.5.0",
"com.novus" % "salat_2.9.1" % "1.9.1",
"se.radley" % "play-plugins-salat_2.9.1" % "1.1"
)
There are no salat and play-salat plugins for scala 2.10 so I specify scala version explicitly. But it takes no effect:

What am I missing?
Salat 1.9.2-SNAPSHOT is available for 2.10.
And let me acknowledge my ignorance: the reason was that I failed to run play command every time I modified Build.scala. The only thing I tried was run, again and again.
