emacs project/build/src/StepProject.scala

で

val servlet = "org.mortbay.jetty" % "servlet-api" % "3.0.pre1" % "provided->default"

どうやら古いservlet-api(2.5)を参照しているのが根本原因らしい。
コンパイルはservlet-api(3.0)で通していて、
クラスパス（Set）の並び順によって偶然実行時にもservlet-api(3.0)を読みに行く（こちらが正しい）場合は正しく動いていて、
なんかの加減でSetの並び順が変わって（フォルダを変えるとかｗそんなのありか）2.5を優先的に読みにいってしまうと動かなくなる、
という話だったと思われる。

val servlet = "org.mortbay.jetty" % "servlet-api" % "3.0.pre1" % "provided->default"
でコンパイル時にも実行時にも必ず3.0.pre1(jetty-7とおそろいにしている。~/.ivy2/あたりを参照)を読むようにすれば万事解決。

参考： 3.0.pre1とか指定したときにivyがダウンロードしにいくのはここ。
