Upgrade to Play Framework 2.2 Securesocial problem

Question

Hi I am trying to upgrade to Play 2.2 and am having some problems getting securesocial to work.

I am using the latest snapshot as was suggested in the forums but get the error below. The verify error indicates compiled source incompatibility somewhere between binaries and the version I am using. I have tried switching between java 1.6 and 1.7 but get the same issue. I know securesocial is only ready for Play 2.1 but there are examples of Play 2.2 using securesocial snapshot. Perhaps I should just downgrade again.

My Build.scala

object ApplicationBuild extends Build {

  val appName = "rm-play"
  val appVersion = "1.0-SNAPSHOT"

  val appDependencies = Seq(
    // Add your project dependencies here,
    javaCore,
    javaJdbc,
    javaEbean,
    "com.google.guava" % "guava" % "15.0",
    "org.codehaus.jackson" % "jackson-core-asl" % "1.9.13",
    "com.dbdeploy" % "maven-dbdeploy-plugin" % "3.0M3",
    "postgresql" % "postgresql" % "9.1-901.jdbc4",
    "joda-time" % "joda-time" % "2.3",
    "com.github.mumoshu" % "play2-memcached_2.10" % "0.3.0.3",
    "net.spy" % "spymemcached" % "2.9.1",
    "com.amazonaws" % "aws-java-sdk"% "1.6.11",
    "ws.securesocial" %% "securesocial" % "master-SNAPSHOT"
  )


  val main = play.Project(appName, appVersion, appDependencies).settings(
    resolvers += Resolver.sonatypeRepo("snapshots"),
    javacOptions in Compile ++= Seq("-source", "1.7", "-target", "1.7")
  )

} 

plugin.sbt

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("com.typesafe.play" % "sbt-plugin" % System.getProperty("play.version")

Answer 1

SecuresSocial 2.1.3 and master-SNAPSHOT are supposed to work with Play 2.2.1. I think that what's causing the problem is that your UserService implementation is being compiled for 1.7 but the code that is trying to load it was compiled for 1.6.

By default Scala 2.10 generates bytecode for 1.6. You can generate 1.7 but as far as I understand that feature is experimental. 1.6 is preferred. I'd change the sbt file to generate 1.6 bytecode. That should make it work.

Answer 2

So it turns out it was a lot more innocuous than just a difference in compile versions.

What was causing the error was the line below, changing it to using the method rather than the field corrected the problem.

In the logs I found the error

Reason: Type 'securesocial/core/java/Token' (current frame, locals[4]) is not assignable to 'model/LocalToken' (stack map, locals[4])

localToken.uuid = token.uuid;

changed to below resolved the issue.

localToken.uuid = token.getUuid();

I am not exactly sure why this helped I don't have all that much experience with scala but the field call generates the method and perhaps it was this causing the problem.
