SBT + Lift - Not being able to build with sbteclipse

I just installed SBT 0.10.1. I'm using Lift 2.4-M3

I can build with Scala 2.9.0-1 but when it tries to search for sbteclipse it just hangs:

[error] {file:/Users/JP/.sbt/plugins/}default-05868e/*:update: sbt.ResolveException: unresolved dependency: com.typesafe.sbteclipse#sbteclipse_2.9.0-1;1.2: not found

The steps I made:

• Put the sbteclipse build.sbt in ~/.sbt/plugins/
• Added scalaVersion := "2.9.0-1" to ~/.sbt/plugins/build.sbt because, for some reason, sbt was always building with Scala 2.8.1
• Copy&Paste Lift scala_29/lift_basic to my project root
• Added build.sbt to both project root and /project/plugins/ like stated in http://www.assembla.com/spaces/liftweb/wiki/Using_SBT
• Changed build.properties sbt.version=0.7.7 to sbt.version=0.10.1

Any ideas on how to have this building properly? Do I need to add any code from the https://github.com/typesafehub/sbteclipse ?

Thank you.

Just found the solution.

First things first, like Daniel said, you cannot have scalaVersion in ~/.sbt/plugins/build.sbt Just remove it form there.

Secondly I updated sbteclipse build.sbt from https://github.com/typesafehub/sbteclipse

Thirdly I copied the content from /project/plugins/build.sbt and added it to ~/.sbt/plugins/build.sbt

Finally I cleaned everything from previous builds and ran sbt. It compiled with no errors whatsoever.

You shouldn't have added scalaVersion := "2.9.0-1" to ~/.sbt/plugins/build.sbt. SBT uses Scala 2.8.1 for itself, and that includes any plugins (such as sbteclipse).

You may add that to your project -- as in build.sbt in the root of your project, not project/plugin/build.sbt --, so that it uses Scala 2.9.0-1, but SBT, and sbteclipse, will continue to use Scala 2.8.1.

Again, SBT and its plugins must use SBT's Scala version, which, at the moment, is 2.8.1.
