How can I fix "not found: object net" and "not found: value Http"?

[Emre Sevinc]

Hello,

I'm trying to run a very simple that I've found on the Rapture web page but I'm receiving  "not found: object net" and "not found: value Http" errors. How can I fix this?

Please see my build.sbt and Scala source code below:

build.sbt

================================================================

name := "belga"

version := "1.0"

scalaVersion := "2.11.2"

libraryDependencies ++= Seq("com.propensive" %% "rapture-core" % "1.0.0")

libraryDependencies ++= Seq("com.propensive" %% "rapture-json-jackson" % "1.0.6")

libraryDependencies ++= Seq("com.propensive" %% "rapture-io" % "0.10.0")

Source code:

================================================================

import rapture._

import core._, io._, net._, uri._, codec._

object ArticleDownloader extends App {

  Console.println("Article Downloader: " + (args mkString ", "))

  // Read a file into a string

  import encodings.`UTF-8`

  val src = uri"http://www.cnn.com/".slurp[Char]

}

sbt session with errors:

==========================================================================

Well, apparently the following dependency was missing in build.sbt:

libraryDependencies ++= Seq("com.propensive" %% "rapture-net" % "0.10.0")

Seems like problem solved!

Yes, you'll need the rapture-net (for network operations) and potentially the rapture-fs (for filesystem operations) packages. They're always released with the same version numbers as rapture-io.

Which documentation were you using? I guess I've neglected to explain this - I'd like to go back and fix that!

Cheers,
Jon

I've found myself jumping between various GitHub pages and http://rapture.io/. I believe having a "Documentation" link at the top of http://rapture.io/ and then providing the authoritative documentation (with clear examples and a link to Scaladoc) can give a huge boost to newcomers to this nice library.

I think another helpful thing would be to include the build.sbt file that allows one to use the example that appears first on rapture.io
