UbuS: 1. Install Java

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
openjdk version "11.0.7" 2020-04-14 LTS
OpenJDK Runtime Environment Zulu11.39+15-CA (build 11.0.7+10-LTS)
OpenJDK 64-Bit Server VM Zulu11.39+15-CA (build 11.0.7+10-LTS, mixed mode)

Install Java

For full installation instruction of AdoptOpenJDK see their official documentation.

(for Ubuntu)

1. Import the official AdoptOpenJDK GPG key by running the following command:

$ wget -qO - https://adoptopenjdk.jfrog.io/adoptopenjdk/api/gpg/key/public | sudo apt-key add -

2. Import the AdoptOpenJDK DEB repository by running the following command:

sudo add-apt-repository --yes https://adoptopenjdk.jfrog.io/adoptopenjdk/deb/

If you get a command not found error, try running:

sudo apt-get install -y software-properties-common

Then repeat the first command.

3. Refresh your package list with apt-get-update and then install your chosen AdoptOpenJDK package. For example, to install OpenJDK 8 with the HotSpot VM, run:

sudo apt-get install -y adoptopenjdk-11-hotspot

Confirm that Java Works

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

$ java -version
openjdk version "11.0.7" 2020-04-14 LTS
OpenJDK Runtime Environment Zulu11.39+15-CA (build 11.0.7+10-LTS)
OpenJDK 64-Bit Server VM Zulu11.39+15-CA (build 11.0.7+10-LTS, mixed mode)
