How to set JDK 19 Oracle for AWS Cloud9 by option (not by install)?

Answer 1

Unclear what environment you're using, but in either case of EC2, or SSH, you'll need to install JDK 19 using the appropriate OS package manager, or tools such as SDKMan. Gradle nor the IDE will download it for you, nor will it be the default as long as Java 11 (or 17) are considered LTS. Best to create your own AMI with it pre-installed.

Or otherwise, use a Dockerfile with Gradle and JDK 19 to compile and/or run your code.
