play framework migrate to 2.1.1 gives me a headache

Question

So I wanted to start working on a play framework project of mine I abandoned 5 months ago, the project was still in version 2.0.4 and seeing 2.1.1 was the latest version I did this tutorial to update the project: http://www.playframework.com/documentation/2.1.1/Migration. (except for doing addSbtPlugin("play" % "sbt-plugin" % "2.1.1") instead to match the current version)

But as soon as I try to do play clean I get this error:

[error] sbt.IncompatiblePluginsException: Binary incompatibility in plugins detected.
[error] Note that conflicts were resolved for some dependencies:
[error]     asm:asm
[error]     asm:asm-tree
[error]     asm:asm-util
[error]     jline:jline
[error]     junit:junit

[error]     commons-codec:commons-codec
[error] Use 'last' for the full log.
Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore? 

I can't find much on the topic except for this link but I don't really understand what fixed the issue there and apparently the asker neither. I also tried to add all the example dependencies in the migration tutorial but that changed nothing.

Is this solvable or should I just revert back to 2.0.4?

EDIT 1-5-12' Added config files, nothing out of the ordinairy I think

Build.scala

import sbt._
import Keys._
import play.Project._

object ApplicationBuild extends Build {

    val appName         = "Workshop0182Host"
    val appVersion      = "1.0-SNAPSHOT"

    val appDependencies = Seq(
      // Add your project dependencies here,
    )

    val main = play.Project(appName, appVersion, appDependencies).settings(
      // Add your own project settings here      
    )

}

plugins.sbt

// Comment to get more information during initialization
logLevel := Level.Warn

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


// Use the Play sbt plugin for Play projects
addSbtPlugin("play" % "sbt-plugin" % "2.1.1")

build.properties

sbt.version=0.12.2

I have tried to do addSbtPlugin("play" % "sbt-plugin" % "2.1.0") but then play clean just says addSbtPlugin uses the wrong version. play clean-all ran fine but nothing changed afterwards

EDIT 1-5-12' Added logs

Here is a link (pastebin) to the error log when I try to run play clean or play run, I think the problem has something to do with the scala version but I have no idea where to go from there.

Answer 1

I have had the same problem, it all turns around sbt version and play version. So in project/build.properties you must have sbt.version=0.12.2 and in project/plugins.sbt addSbtPlugin("play" % "sbt-plugin" % "2.1.0") then

play clean
play ~run

Try to create new project from scratch with 2.0.4 version and then migrate it to 2.1.0

In any way, it would be nice to see your config files.
