无法添加自定义SBT操作
我刚刚开始使用SBT。 要添加自定义操作，我做了以下任务，并将该.scala文件添加为SBT wiki指南中的“项目”文件夹。
//MyProject.scala
import sbt._
class HelloWorldProject(info: ProjectInfo) extends DefaultProject(info)
{
lazy val hi = task { println("Hello World"); None }
}
在添加scala src文件进行配置后，项目文件夹的布局看起来像这样。
/development/scala/SomeScalaProject/ |~lib/ |~project/ | |~boot/ | | |~scala-2.7.7/ | | | |~lib/ | | | | |-scala-compiler.jar [RO] | | | | `-scala-library.jar [RO] | | | `~org.scala-tools.sbt/ | | | `~sbt/ | | | `+0.7.4/ | | |~scala-2.8.1/ | | | `~lib/ | | | |-scala-compiler.jar [RO] | | | `-scala-library.jar [RO] | | `-sbt.boot.lock | |-build.properties | | | `-MyProject.scala //here | |+src/
但即使在“重新加载”或“更新”后，在SBT中运行hi任务根本不可用。 我错过了什么？

这是我的错误。 :(
“MyProject.scala”应位于/ project / build目录下而不是/ project目录下。
