Mac下安装sbt

为了可以用Eclipse编译基于Scala的Spark Project，需要安装sbt

环境：OS X Yosemite 10.10.3

1.安装Xcode

因为要在终端用macports安装sbt，而Xcode是macports安装的前提，所以要先去APPstore下载Xcode，并安装其command line developer tools。

安装比较简单，详见：https://guide.macports.org/#installing

2.安装macports

去官网下载其安装包并安装，和安装QQ一样简单

详见：https://guide.macports.org/#installing

3.安装sbt

在终端下输入一下命令：

port install sbt

看到类似以下信息就算安装完了：

...这里省略很多log...
downloading https://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/apply-macro/0.13.7/jars/apply-macro.jar ...

    [SUCCESSFUL ] org.scala-sbt#apply-macro;0.13.7!apply-macro.jar (9005ms)

:: retrieving :: org.scala-sbt#boot-app

    confs: [default]

    51 artifacts copied, 0 already retrieved (15709kB/378ms)

Getting Scala 2.10.4 (for sbt)...

    5 artifacts copied, 0 already retrieved (24459kB/195ms)

[info] Set current project to hello (in build file:/Users/apple/Desktop/hello/)

4.跑个hello world

为了验证sbt是不是安装成功，我们跑个hello world试试

$ mkdir hello

$ cd hello

$ echo 'object Hi { def main(args: Array[String]) = println("Hi!") }' > hw.scala

$ sbt

...

> run
[info] Updating {file:/Users/apple/Desktop/hello/}hello...
[info] Resolving org.fusesource.jansi#jansi;1.4 ...
[info] Done updating.
[info] Compiling 1 Scala source to /Users/apple/Desktop/hello/target/scala-2.10/classes...
[info] Running Hi 
Hi!
[success] Total time: 4 s, completed Jul 8, 2015 11:17:46 AM

这是官网的示例，按照他的做并出现相同的结果就对了！

到此，mac下安装sbt就结束了。
