Windows上的sbt 0.12.4。

首先，我进入项目目录，即example - sbt下的Scala项目。当我运行sbt时，我收到以下错误：

Answer 1

实用的“解决方案”可能有助于您立即投放：将所有in Test ProgFunBuild.scala的{{1}}替换为in sbt.Test，然后重试。

尽管如此，你的环境仍然存在一些问题。

Answer 2

运行sbt时会发生的事情是它不是编译你的源而是编译sbt的构建定义。问题似乎是找不到Test。我只能模糊地猜测......

您是否以任何方式触摸了该文件ProgFunBuild？
您是否意外将正常的源代码放在project子目录中？也许你这样做并且在那里定义了一个对象Test哪个阴影sbt的Test范围？
你从什么目录运行sbt？您应该位于示例的根文件夹中，不在project目录中。

您应该具有以下布局：

project/ProgFunBuild.scala
project/build.properties    (optional)
build.sbt                   (optional)
src/main/scala/...          (your sources in there)

加载Scala构建文件时为什么会出现编译错误？
