加载Scala构建文件时为什么会出现编译错误？

Question

在Windows上为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 ，我收到以下错误：

Answer 1

一个实用的“解决方案”，可能有助于让你现在运行：在ProgFunBuild.scala中用in sbt.Test in Test替换所有出现的那些，然后再试一次。

尽管如此，你的环境仍然存在一些问题。

Answer 2

运行sbt时会发生什么，它不是编译源代码而是编译sbt的构建定义 。 问题似乎是找不到Test 。 我只能隐约地推测...

• 你有没有以任何方式触摸ProgFunBuild文件？
• 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？
• 您从哪个目录运行sbt？ 您应该位于示例的根文件夹中， 而不是在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)
