Compilation failed: error while loading AnnotatedElement, ConcurrentMap, CharSequence from Java 8 under Scala 2.10?

Question

I\'m using the following:

• Scala 2.10.4
• Scalatra 2.2.2
• sbt 0.13.0
• java 1.8.0
• casbah 2.7.2
• scalatra-sbt 0.3.5
<

Answer 1

I solved this by using:

<dependency>
    <groupId>org.scala-lang</groupId>
    <artifactId>scala-library</artifactId>
    <version>2.10.2-RC2</version>
</dependency>

My environment is:

• JDK 8
• Maven
• Scala

Answer 2

I also got the same issue in Ubuntu 14.04 but I solved by removing the scala 2.10 and installing 2.11

wget www.scala-lang.org/files/archive/scala-2.11.7.deb

 

dpkg -i scala-2.11.7.deb

Now try.

Answer 3

That was a lot of reconfiguration for me to get it to work, here is my (NOW) working build.sbt using, sbt 0.13.15 and scala 2.10.4 and jdk 1.8.1_131

name := "ScalaTelemetryManagerApi"
version := "1.0"
scalaVersion := "2.10.4"
scalacOptions := Seq("-unchecked", "-deprecation", "-encoding", "utf8")

libraryDependencies ++= {
  Seq(
    "io.spray"            %   "spray-can"     % "1.3.1",
    "io.spray"            %   "spray-routing" % "1.3.1",
    "io.spray"            %   "spray-testkit" % "1.3.1",
    "com.typesafe.akka"   %%  "akka-actor"    % "2.3.2",
    "com.typesafe.akka"   %%  "akka-testkit"  % "2.3.2",
    "org.specs2"          %%  "specs2-core"   % "3.6",
    "com.github.seratch"  %%  "awscala"       % "0.5.+",
    "org.scalaz"      %%  "scalaz-core"   % "7.2.14"
  )
}
