Migrating the game in 2.1.1 gives me a headache

So, I wanted to start work on a project of my career that I left 5 months ago, the project was still in version 2.0.4, and, seeing that 2.1.1 was the latest version, I made this tutorial to update the project: http: //www.playframework.com/documentation/2.1.1/Migration . (except that addSbtPlugin ("play"% "sbt-plugin"% "2.1.1") is instead the current version)

But as soon as I try to play in its purest form, 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] Use 'last' for the full log.
Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore? 

I can’t find much on this subject except this link , but I really don’t understand that the issue is fixed there, and apparently nobody is interested. I also tried adding all the examples of dependencies to the migration tutorial, but didn't change anything.

Is it solvable or will I just go back to 2.0.4?

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 tried to do addSbtPlugin("play" % "sbt-plugin" % "2.1.0"), but then play cleanjust says addSbtPlugin is using the wrong version. play clean-all ran fine, but nothing changed after that
