sbt.ResolveException: download failed: org.slf4j#slf4j-api;1.6.6

Problem


 When I ran play run , I have the following error :

[error] (*:update) sbt.ResolveException: download failed: org.slf4j#slf4j-api;1.6.6!slf4j-api.jar
[warn] some of the dependencies were not recompiled properly, so classloader is not avaialable

Solution

vi ./project/plugins.sbt

You only have to edit this file and add the last version of play (2.1.0) :

// 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" % "2.1.0")

Then you can launch play run again

play 2.1 : Create yout first projetc with IntelliJ Tips

Create a project with Play is easy :

$ play new my-app 
$ cd my-app 
$ play idea


However, I had some diificulties with how to import in IntelliJ.In the documentation, it says that you have to import a module.But it doesn't work for me.
To succes, I've just done the following :

File --> Open

And now it works every times :-)
