如何设置IntelliJ + Scala +规范+ sbt项目？

Question

I am trying to setup an empty sbt project with specs2 for Scala (2.10) with IntelliJ (12.1) support and I am getting this error when I do sbt compile on empty project directory:

% sbt compile

My build.sbt file looks like this:

name := "scalgos"

version := "0.0.1"

scalaVersion := "2.10.1"

libraryDependencies += "org.specs2" %% "specs2" % "1.14" % "test"

I installed sbt by doing brew install sbt :

% brew info sbt                                                                                                                                                                                   
sbt: stable 0.12.2, devel 0.13.0-M1
http://www.scala-sbt.org
/usr/local/Cellar/sbt/0.11.3-2 (3 files, 1.1M) *
https://github.com/mxcl/homebrew/commits/master/Library/Formula/sbt.rb
==> Caveats
You can use $SBT_OPTS to pass additional JVM options to SBT.
For convenience, this can specified in `~/.sbtconfig`.

For example:
    SBT_OPTS="-XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=256M"

Brew says I have sbt 0.12 but when I sbt --version I get:

% sbt --version                                                                                                                                                                                    
sbt launcher version 0.11.3-2

I tried to atleast generate the IntelliJ files by putting this in my $PROJECT_DIR/projects/plugins.sbt:

resolvers += "sbt-idea-repo" at "http://mpeltonen.github.com/maven/"

addSbtPlugin("com.github.mpeltonen" % "sbt-idea" % "1.2.0")

But when I did sbt gen-idea , I got this error:

% sbt gen-idea

Can someone post a sample build.sbt that would generate IntelliJ 12.1 files for Scala 2.10.1 and sbt?

I checked in my project here: https://github.com/pathikrit/scalgos

Please advise what am I doing wrong???

Answer 1

you can use this project i built that provides what you are looking for out of the box

Skeleton

I'm planning to upgrade the sbt config and latest and greatest libs (sbt-idea 1.3.0 and scala 2.10.1) tonight.

enjoy!

Answer 2

you should update sbt version to 0.12.X, create file "project/build.properties", and put "sbt.version=0.12.1"

i forked your repo and edited the sbt version, it seems work fine on my machine
