Dependency issues Posted: Dec 7, 2012 2:21 PM

I am banging my head against the wall. I am having a hell of a time with sbt and the dependencies

Somehow I was able to go through the first example, I had the same issue and not sure how I solved it. But when I got the test chapter and tried to add the test dependencies everything crapped out.

I have tried a build.sbt, and the build file created by the akka-scala-template


here is my build file:
scalaVersion := "2.10.0-RC3"

resolvers += "Typesafe Repository" at "http://repo.typesafe.com/typesafe/releases/"

libraryDependencies ++= Seq(
"com.typesafe.akka" % "akka-actor" % "2.10.0-RC3",
//"org.scalatest" %% "scalatest" % "2.0.M5" % "test"
"com.typesafe.akka" % "akka-testkit" % "2.1"
)


I have the typesafe resolver it will not find those dependencies (I have tried the snapshot repo as well) It appears to me what sbt is looking for is a different path than what is published in the typesafe repo.

If I remove the typesafe resolver sbt update works just fine but then I get a complete sbt compile failure, because it is not finding any of the akka imports.

I am going crazy here, please help!

and if I explicitly give the url via the 'from' option, update will work, but again I get the compile errors

The current flux in the release candidates is making things a bit rough. I'll have to see about writing things using the typesafe stack instead, but I wanted to make things as short as possible :)

The following works for me:

name := "some_project"

version := "0.1"

scalaVersion := "2.10.0-RC3"

libraryDependencies ++= Seq(
"com.typesafe.akka" % "akka-actor" % "2.1.0-RC3" cross CrossVersion.full,
"com.typesafe.akka" % "akka-agent" % "2.1.0-RC3" cross CrossVersion.full,
"com.typesafe.akka" % "akka-testkit" % "2.1.0-RC3" cross CrossVersion.full,
"com.typesafe.akka" % "akka-dataflow" % "2.1.0-RC3" cross CrossVersion.full,
"com.typesafe.akka" % "akka-remote" % "2.1.0-RC3" cross CrossVersion.full,
"com.typesafe.akka" % "akka-camel" % "2.1.0-RC3" cross CrossVersion.full,
"org.scalatest" % "scalatest_2.10.0-RC3" % "2.0.M5-B1"
)

thanks for the quick response, that works and I may have messed it up by changing a bunch of the dependencies and using CrossVersion liberally, I noticed that I had a 2.9.2 target directory that was not suppose to be there.

Awesome book though, really well done, probably the worst time for me to purchase right before a major release :)

Heh :) Yeah, the timing's a bit rough right now. Just before I released, a lot of stuff got moved from Akka to Scala, so I had to make a lot of changes. Then, about three days after I released, Scala changed stuff that broke a lot of the example code. Fun times :)

Thanks for sticking with it!

Is this (2.10.0-RC3) what you'd recommend using for working through the book, just because that's the version you're on? Or, if you're now using the 2.10 release, any chance you could post an updated build.sbt?

This works for me:

name := "AkkaConcurrency"

version := "0.1.0-SNAPSHOT"

scalaVersion := "2.10.0"

resolvers += "Typesafe Repository" at "http://repo.typesafe.com/typesafe/releases/"

libraryDependencies ++=
"com.typesafe.akka" %% "akka-actor" % "2.1.0" ::
"com.typesafe.akka" %% "akka-testkit" % "2.1.0" % "test" ::
"org.scalatest" %% "scalatest" % "2.0.M5b" % "test" ::
Nil

If I were you guys, I'd just use giter8 to pull down the typesafe akka template. It uses the .scala version of the SBT file and should take care of all those dependencies and such for you.
