问题 I have a large and moderately complex web application, using the standard Typesafe Stack of Play, Scala and Akka. (I'm in the process of adding scala.js, but this problem predates that.) A couple of months ago, I upgraded to the current Activator-based version of the world (having fallen behind the times), and that's mostly worked fine. But ever since then, I am semi-frequently getting a weird error when I try to compile: [Querki] $ compile [trace] Stack trace suppressed: run last scalajvm

问题 Im trying to achieve something similar to the first example under "Sending large amounts of data" at http://www.playframework.org/documentation/2.0/ScalaStream. What I am doing differently is that I have more than one file that I want to concatenate in the response. It looks like this: def index = Action { val file1 = new java.io.File("/tmp/fileToServe1.pdf") val fileContent1: Enumerator[Array[Byte]] = Enumerator.fromFile(file1) val file2 = new java.io.File("/tmp/fileToServe2.pdf") val

问题 I have a Play 2.0 app that uses sbt 0.11.2 . However when I set up a new Play server, it grabbed the latest version of sbt 0.11.3 . Now when I run sbt compile on the new server, it complains Detected sbt version 0.11.2 Cannot find sbt launcher 0.11.2 Please download: /sbt-launch.jartypesafe.artifactoryonline.com/typesafe/ivy-releases/org.scala-tools.sbt/sbt-launch/0.11.2 /sbt-launch.jarc2-user/.sbt/.lib/0.11.2 I tried downloading sbt-launch 0.11.2 and putting in the same folder as sbt but
