Discussion:
Project description OpenJDK 22 was released on 19-MAR-2024. The OpenJDK project has been releasing Early Access (EA) binaries for many months now. It would be nice to be able to install OpenJDK 22 as a Nix package and also to begin development of dependent Nix packages (e.g. ) Metadata homepage URL: source URL: (update: is open now) license: GPL with Classpath Exception platforms: unix, linux, darwin, others I'm fairly new to Nix (but loving it so far) so I'm not 100% sure this whether this should be a "new package request" (as Nix keeps multiple versions of OpenJDK available as different packages) or a "package update request" (since jdk22 is an updated version of jdk21.) If I need to change this or anything else in the issue please let me know and I will try to fix it.
