I have a problem where my Scala project will not build in sbt 0.13.1 and Scala 2.10.3 unless I DO NOT try to add the sbteclipse plugin (2.4.0).

I recently switched from Linux Mint 14 Xfce to Fedora 20 Xfce. When I was on Linux Mint 14, I developed a small RESTful service using Scala, Akka, Spray, and Slick, building using sbt. After installing Fedora 20, I installed all the packages necessary to resume work on that REST service. To that end, I ran 

yum install -y java
yum install -y scala
yum install -y sbt

This installed OpenJDK 1.7.0_51, Scala 2.10.3, and sbt 0.13.1.

When my plugins.sbt contains the line 

addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.4.0")

running sbt from the command line generates the following error: 

sbt.ResolveException: unresolved dependency: org.scala-lang#scala-library;2.10.3: configuration not found in org.scala-lang#scala-library;2.10.3: 'compile'

This is a problem whether the plugins.sbt is located in <projectfolder>/project, or in ~/.sbt/0.13/plugins.

When I comment-out the 

// addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.4.0")

line from the plugins.sbt, the build functions normally.

I recreated the problem using a simple test project that just creates a single Scala class with a one-line print statement. The problem continues to occur independently of whatever other plugins, repositories, or library dependencies I define in the plugins.sbt and build.sbt files.

The simple test project is located at testproject on Github

The REST service is located at airport-web on Github

Please note that the REST service has commented-out the addSbtPlugin...sbteclipse line in plugins.sbt.

First of all, you have to be sure witch sbt version you are using, You might have an unexpected version in your path. You can check it with:

sbt sbt-version

One you know what is your version you can select the right version.

  • sbt version -> sbteclipse version
  • 0.13 and up......-> 2.4.0
  • 0.12 ............... -> 2.1.2
  • 0.11.3.............. -> 2.1.1
  • 0.11.2.............. -> 2.0.0

  • One thing you can do is to factor out the tooling into ~/.sbt. See one way to do that here: https://github.com/jkleckner/dotsbt/blob/master/README.md – Traveler Oct 07 '14 at 01:54

I had same issue and I finished for using last versions of everything:

sbt: 0.13.2 sbteclipse: 2.5.0

I removed all eclipse configuration files for my project (.classpath,.cache,.project,...) I removed all folders generated by previous versions of sbt (target, bin,..) I also removed all java libraries from home ~/.ivy2 to avoid possible conflicts with previously downloaded versions

Then I compiled as : sbt compile Then I add plugins.sbt to the /project folder and call again as: sbt eclipse.

No more errors appeared and I succeeded to import from eclipse. I'm not sure about what was wrong because i didn't find anything on the web. But this worked for me.
