install play-authenticate plugin

Question

It seems the "play-authentication" plugin is not installed if i follow instructions at github https://github.com/joscha/play-authenticate/blob/master/samples/java/Getting%20Started.md

my eclipse IDE cannot find packages starting with "com.feth". i add the dependencies to Scala.build as described in readme above, then run clean and dependencies then compile..but the com.feth packages are not found. which means the play-auth plugin was not installed correctly. i wonder if there is a way to install the play-authenticate module correctly . am i missing something in the beside what is mentioned in readme above? it seems both dependencies of deadbolt-2 and play-authenticate are not resolved and installed. i also remarked a '%%' in the dependencies declaration in Scala.Build. but even if i use a single '%' the dependencies are not resolved and plugins are not installed. any help is much appreciated

my /project/Scala.Build file is below:

import sbt._
import Keys._
import PlayProject._

object ApplicationBuild extends Build {

    val appName         = "r2s2"
    val appVersion      = "1.0-SNAPSHOT"


 val appDependencies = Seq(
      "play-aws"      % "play-aws_2.9.1"      % "0.1",
      "be.objectify"  %%  "deadbolt-2"        % "1.1.3-SNAPSHOT",
      "com.feth"      %%  "play-authenticate" % "0.2.3-SNAPSHOT"
    )


    val main = PlayProject(appName, appVersion, appDependencies, mainLang = JAVA).settings(


      resolvers += Resolver.url("Objectify Play Repository", url("http://schaloner.github.com/releases/"))(Resolver.ivyStylePatterns),
      resolvers += Resolver.url("Objectify Play Repository", url("http://schaloner.github.com/snapshots/"))(Resolver.ivyStylePatterns),

      resolvers += Resolver.url("play-easymail (release)", url("http://joscha.github.com/play-easymail/repo/releases/"))(Resolver.ivyStylePatterns),
      resolvers += Resolver.url("play-easymail (snapshot)", url("http://joscha.github.com/play-easymail/repo/snapshots/"))(Resolver.ivyStylePatterns),

      resolvers += Resolver.url("play-authenticate (release)", url("http://joscha.github.com/play-authenticate/repo/releases/"))(Resolver.ivyStylePatterns),
      resolvers += Resolver.url("play-authenticate (snapshot)", url("http://joscha.github.com/play-authenticate/repo/snapshots/"))(Resolver.ivyStylePatterns),
      resolvers += "Local Play Repository" at "/home/othman/play-2.0.4/repository/local"
    )

When you are adding new dependencies to a play project,First you have to use the 'reload' command to download updated jar from internet and after that just fire 'eclipse' command again to re-create eclipse related config files. Then you should be able to find updated jars on your eclipse classpath.

Hope it helps!

I had the similar problem with Play-2.2.1 while trying to add play-authentication dependency to my project. Mentioned above Getting started guide suggests to use resolvers like this:

resolvers += Resolver.url("play-authenticate (snapshot)", url("http://joscha.github.com/play-authenticate/repo/snapshots/"))(Resolver.ivyStylePatterns)

But what I've finally found is that Resolver.ivyStylePatterns does not work! With this setting I always got "UNRESOLVED DEPENDENCIES" error.

Solution that works for me:

resolvers += Resolver.url("play-authenticate (snapshot)", url("http://joscha.github.io/play-authenticate/repo/snapshots/"))( Patterns("com.feth/[module]/[revision]/[type]s/[artifact].[ext]") )

The list of changes and important points:

1. top domain of github changed from com to io (but old one looks working too)
2. instead of Resolver.ivyStylePatterns I use my own pattern constructed by Patterns helper. you can find more info about tokens in ivy documentation.
3. NB! I don't use [organization] token cause it ends with 'com/feth' - not 'com.feth' as github needs.

If you change the Build.scala you have to use the reload command o relaunch the play enviroment.

It sounds to me like you did not copy the 'com' folder in the right place, which would cause that error. It's supposed to be copied into /app/com. Not sure if this is your problem or not, you may have this done properly.
