Graphlytic requires Java to be installed. For required version see Requirements. If you have installed required version you can skip installation of Java.

You can test whether you have the correct Java platform by running from command line:

$ java -version
java version "1.8.0_202-ea"
Java(TM) SE Runtime Environment (build 1.8.0_202-ea-b03)
Java HotSpot(TM) 64-Bit Server VM (build 25.202-b03, mixed mode)

Install Homebrew

If you have already installed Homebrew, you can skip this step. More information can be found here.

 $ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install Java

(for macOS X 10.13 High Sierra)

$ brew update
$ brew tap caskroom/versions
$ brew cask install java8

Confirm that Java Works

Once the steps above have been done, it should be possible to check the java version and see output similar to this:

$ java -version
java version "1.8.0_202-ea"
Java(TM) SE Runtime Environment (build 1.8.0_202-ea-b03)
Java HotSpot(TM) 64-Bit Server VM (build 25.202-b03, mixed mode)
