Installation instructions

SBT is the "Scala Build Tool". We will use it to compile & run our code.

❗ You need a working installation of Java 8 (OpenJDK or Oracle JDK).

❗ If you're a Ubuntu user, you need to upgrade to at least Xenial (16.04 LTS).

Windows

Go to the SBT download page and install it from there.

Linux/macOS

Run the following commands:

$ ./setup
$ ./sbt

After downloading the entire Internet, this should load up the SBT shell.

Alternatively, you can install SBT from your distribution's package manager:

• Arch Linux: sbt
• Homebrew: sbt
• deb-based/rpm-based: additional repository

Development

Depending on your installation, run ./sbt or sbt in the repository root. SBT will print something like this (or similar):

[info] Loading global plugins from /home/lars/.sbt/0.13/plugins/project
[info] Loading global plugins from /home/lars/.sbt/0.13/plugins
[info] Loading project definition from /home/lars/proj/katsconf2017/project
[info] Set current project to katsconf2017 (in build file:/home/lars/proj/katsconf2017/)
>

This is the SBT shell where you can type commands. As a first step, type update, which will fetch all necessary dependencies. To compile, run, or test, type compile, run, or test, respectively. To exit, press Ctrl-D or type exit.
