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 (17.0.8 at the time of writing) from: https://www.oracle.com/java/technologies/downloads/#jdk17-mac
Verify the installation¶
After the installation, please verify the version in a shell:
java --version
You should see something similar:
java 17.0.8 2023-07-18 LTS
Java(TM) SE Runtime Environment (build 17.0.8+9-LTS-211)
Java HotSpot(TM) 64-Bit Server VM (build 17.0.8+9-LTS-211, mixed mode, sharing)

Do not explicitly set JAVA_HOME
