JDK

You most probably already have jdk on your system. The CEDAR developer team uses Oracle JDK 17, 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.

Install JDK 17

Please download and install the latest Oracle JDK 17 (17.0.13 at the time of writing) from: https://oracle.com/java/technologies/downloads/#java17-mac

Verify the installation

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

java --version

You should see something similar:

java 17.0.13 2024-10-15 LTS
Java(TM) SE Runtime Environment (build 17.0.13+10-LTS-268)
Java HotSpot(TM) 64-Bit Server VM (build 17.0.13+10-LTS-268, mixed mode, sharing)

About JAVA_HOME

Do not explicitly set JAVA_HOME at this time, we will set it in the next step using jenv
