SBT installs SBT under--mac in the Scala Eclipse environment

In order for you to compile Scala-based spark Project with Eclipse, you need to install SBT

Environment: OS X Yosemite 10.10.3

1. Install Xcode

Because you want to install SBT in the terminal with MacPorts, and Xcode is the premise of macports installation, go to AppStore to download Xcode first and install its command line developer tools.

Installation is relatively simple, see: https://guide.macports.org/#installing

2. Installing MacPorts

Go to the official website to download its installation package and install it as simple as installing QQ

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

3. Install SBT

Enter the command below the terminal:

Port Install SBT

See a message similar to the following if the installation is finished:

4. Run a Hello World

To verify that SBT is not installed successfully, let's run a Hello World and try

$ mkdir hello$ CD hello$ echo ' object Hi {def main (args:array[string]) = println ("hi!")} ' > hw.scala$ sbt...> Run

This is an example of the official website, according to his do and appear the same result is right!

This is the end of the installation of SBT under Mac.
