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

I\'m using the following:

• Scala 2.10.4

• sbt 0.13.0
• java 1.8.0
• casbah 2.7.2
• scalatra-sbt 0.3.5

I had the same problem. However by switching to Java 7 my problem is resolved. So now this configuration works for me:

sbt 0.13.8
scala 2.11.7
java 7
