播放2.2.1：intellijCommandSettings（“JAVA”）无法正常工作

Question

在Play 2.1.1中，我在Build.scala中使用：

override def settings = super.settings ++ play.Project.intellijCommandSettings("JAVA")

现在，我使用Play 2.2.1。但是intellijCommandSettings（“JAVA”）不再起作用了：

found   : String("JAVA")
required: Int
override def settings = super.settings ++ play.Project.intellijCommandSettings("JAVA")
                                                                               ^ 
one error found
(compile:compile) Compilation failed

我该怎么办？
