JDK

You most probably already have jdk on your system. The CEDAR developer team uses Oracle JDK 11, and we strongly suggest that you use the same, for compatibility reasons.

Important

Please note, that a JDK is needed to configure and run CEDAR based on this guide. A JRE will not be enough.

We strongly suggest to use the macOS Installer version available at Oracle's download site.

Download JDK

Please download the latest available version of JDK 11 from:

https://www.oracle.com/java/technologies/javase-jdk11-downloads.html

You will need to log in to be able to download the JDK.

Install JDK

Install the downloaded package.

Verify JDK

After the installation, please verify the version in a shell:

java --version

You should see something similar:

java version "11.0.9" 2020-10-20 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.9+7-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.9+7-LTS, mixed mode)
