SBT - Class not found, continuing with a stub
<p>I am currently migrating my Play 2 Scala API project and encounter 10 warnings during the compilations indicating :</p>

<pre><code>[warn] Class play.core.enhancers.PropertiesEnhancer$GeneratedAccessor not found - continuing with a stub.
</code></pre>

<p>All of them are the same, and I don't have any other indications. I've searched a bit for other similar cases, it's often because of the JDK version and so on but I'm already in 1.8.</p>

<p>Here's what I have in plugins.sbt :</p>

<pre><code>addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.5.3")

addSbtPlugin("org.scalastyle" %% "scalastyle-sbt-plugin" % "0.8.0")

addSbtPlugin("com.sksamuel.scapegoat" %% "sbt-scapegoat" % "1.0.4")
</code></pre>

<p>and in build.sbt :</p>

<pre><code>libraryDependencies ++= Seq(
  cache,
  ws,
  "org.reactivemongo" %% "play2-reactivemongo" % "0.10.5.0.akka23",
  "org.reactivemongo" %% "reactivemongo" % "0.10.5.0.akka23",
  "org.mockito" % "mockito-core" % "1.10.5" % "test",
  "org.scalatestplus" %% "play" % "1.2.0" % "test",
  "com.amazonaws" % "aws-java-sdk" % "1.8.3",
  "org.cvogt" %% "play-json-extensions" % "0.8.0",
  javaCore,
  "com.clever-age" % "play2-elasticsearch" % "1.1.0" excludeAll(
    ExclusionRule(organization = "org.scala-lang"),
    ExclusionRule(organization = "com.typesafe.play"),
    ExclusionRule(organization = "org.apache.commons", artifact = "commons-lang3")
    )
)
</code></pre>

<p>Don't hesitate if you need anything else :)</p>

<p>It's not something that blocks me but I'd prefer avoid these 10 warnings everytime I recompile my application.</p>

<p>Thank you ! :)</p>
