Question

创建一个示例Scala项目结构（在我的基于OS X Mavericks的计算机上），如下所示：

在sample_project目录中：

src
    main
      java
      scala
        Hello.scala
      resources
    test
      java
      scala
      resources
 build.sbt

Hello.scala：

object Hello {
    def main(args: Array[String]) = println("Hello!")
}

build.sbt：

name := "hello"

version := "1.0"

scalaVersion := "2.11.1"

将build.properties放在sample_project / project下：

sbt.version=0.13.5

当我尝试使用＆＃34; sbt＆＃34;根文件夹中的命令：

/sample_project $ sbt
Getting org.scala-tools.sbt sbt_2.8.1 0.13.5 ...

Answer 1

这看起来像sbt版本不匹配。在project下创建一个sample_project目录，在其中创建一个名为build.properties的文件，其中包含以下内容：

sbt.version=0.13.5

Answer 2

您似乎有一个旧的启动器版本的sbt，可能甚至太旧而无法应对新的0.13.5。

尝试update您的启动器到最新版本。在MacOS上，最简单的方法是使用Homebrew包管理器。如果尚未完成，请使用以下命令安装：

$ ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

然后，安装sbt：

$ brew install sbt
