I’m new to Scala & sbt, and I’m trying to compile a project that imports akka.stm._.

When I try running sbt compile the compilation fails with a message point to that point.

I tried using
https://github.com/paulp/sbt-extras
so I’ll have the exact sbt version defined in the “build.sbt” file, but it did not help.

I downloaded the akka-2.0.3.tgz and opened the files, but I don’t understand exactly how to install them by default or how to tell sbt to use them.

I also noticed that the build.sbt file contains:

resolvers += "repo.codahale.com" at "http://repo.codahale.com"

libraryDependencies ++= Seq(
//  "com.codahale" % "simplespec_2.9.0-1" % "0.3.4"
  "com.codahale" % "simplespec_2.9.0-1" % "0.4.1"
//  "se.scalablesolutions.akka" %% "akka-sbt-plugin" % "2.0-SNAPSHOT"

I tried uncommenting out the “se.scalablesolutions.akka” (assuming the programmer used the akka-library of that version), but it only printed the message:

[error] Error parsing expression.  Ensure that there are no blank lines within a setting.

(There are no blank lines, I just deleted the ‘//’ and replaced the double ‘%’ with a single one)

How do I tell the sbt to find the akka jar files in their place? Can I add another resolver to solve this problem?

I know this kind of question doesn’t fit in stackoverflow, but can you at least refer me to some manuals I should read inorder to solve this?

    OK, first of all I want to apologize for the newbie question.
    (Stackoverflow should make a separate “newbie” section)

    First, the elements in the Seq part should be separated by comma.
    Second, the akka snapshots were moved to http://repo.akka.io/snapshots so I fixed the build.sbt to:

    resolvers += "repo.codahale.com" at "http://repo.codahale.com"
resolvers += "akka" at "http://repo.akka.io/snapshots"

libraryDependencies ++= Seq(
//  "com.codahale" % "simplespec_2.9.0-1" % "0.3.4"
  "com.codahale" % "simplespec_2.9.0-1" % "0.4.1",
  "com.typesafe.akka" % "akka-stm" % "2.0-SNAPSHOT" 
)

    And the compilation finished successfully.

    I don’t know if this is the exact configuration in which the original compilation was done, but this issue doesn’t disturb me at the moment.
